MIG Welding Basics For BEGINNERS!! How To Set Up Your Welder + Tips, Tricks & Techniques!!

[@michaelrichter1465]

This is the most informative welding video I think I've ever seen on any channel so far. I'm retired now but still like to learn what I can from experienced guys like you Carl. Good job (wrote this halfway through, don't let me down on the overhead cause it's coming up right now!) Btw your buddy Brent coulda used your help making some tooling for his power hammer the other day lol. I made a point to tell him too....thx for the video bud.

[@MakeItKustom]

Yeah, when I go visit him I’m going to see if I can’t make his days a little bit smoother

[@frankfurther3828]

I told him also!

[@thef71]

Yes I've watched millions of vids as well I've been welding for about 30 years and he did it spot on I really enjoyed it and am going to watch it again

Glad I found your channel. You're such an incredible and humble artisan and an awesome teacher as well! I couldn't ask for anything better.

[@johnnyringo1258]

I've been welding since I was a 13yo farm boy . I took 4yrs of welding classes in high school, all stick welding. I wasn't good enough to be a certified welder, but I have done a LOT of welding over the years. I didn't use MIG until I was in my mid-thirties and have yet to use a TIG machine. I'm now in my 50's (and probably as old as Karl's Dad), but I found myself smiling and nodding my head throughout this entire video. This young man seemed genuinely excited to share his knowledge and did a bang up good job! Thanks Karl! Subscribed.

[@King-oj8hr]

Damn started at 13 and then 4 years of classes and still never good enough to get certified? You should’ve just kept all that to yourself. 😂

I’m a beginner in my mid-60’s. I’m also an aerospace engineer that has designed and structurally analyzed welds in mechanical design. This is by far, the best teaching video for migrating welding that I’ve seen. Congratulations on a fine presentation and teaching job!

[@ianmac2963]

FINALLY !!!!!!!!!!!!!!! I've watched more than 100 instructional MIG videos ... ... and not getting the results I wanted ... BUT NOW ... ... YOU Sir ... are a MASTER TEACHER ... a TRUE PEDAGOGUE ... THANK YOU SO MUCH !!!!!!!!!!!!!!!!!!!

[@huckwild6464]

people need to stop for a second and realize this man is giving us this content for free. thank you for this its amazing

[@jdwisdom9433]

After 50+ years of mig welding I thought I'd watch your instructional video on how to do it cause I just might learn something useful. I was right. I learned a lot!! So much depends on the rhythm plus the sound of the welding in creating a proper weld! Thank You, JD

[@Mike-xt2ot]

Best instructional video for beginners ive ever seen. I am 54 and have been doing non structural hobby welding for almost 30 years using proper mig, flux core and stick welding and your way of teaching allowed even a " my welding isnt finer so i wear out alot of grinders " kind of welder to my beads looking far better than ever before. I learn alot from your content. Been a way back subscriber and your metal techniques and making your own body tool videos were a game changer for me as well. I am very grateful to you for sharing your talent and amazing skills with us.

[@richardizui703]

I'm a 73 year old beginner welder here. Your video showed me more good information about MIG welding than anything else on KZbin. Thanks for a great video! Much appreciated!

[@NickSchepis-u2y]

43 yrs old and just staring to weld and this video was very informative and easy to follow with great tips for me to learn. Thanks👍🏼

[@davidsnyder2000]

As a bodyman of 31yrs, I’ve had very little formal training even with ICAR classes regarding welding…it’s sad. But your video Karl really filled in some gaps for me as to the finer points of welding. I always got advice from other bodymen, and that there way was the best way to weld, but it never looked perfect. I appreciate the you using the gifts God gave you to help others. You have free will my friend, and I’m happy with your decisions to help others. My thoughts and prayers are with you ❤️🙏🙂

[@ericgrasholm7470]

I like what you did there David "filled in some gaps" agreed great help.

Gaps .. good one !! 😂

[@peterpowell4821]

I watch and follow quite a few welding channels, and I must say that I have never learned so much in such a short amount of time. Karl, you have considerable talent and are a natural teacher. Thank you for taking the time to put this video together just for the benefit of your followers. Also, excellent camera work 👏.

[@MakeItKustom]

Thanks so much Peter I’m so glad to hear it!

[@bearing1a111]

It has been said many times before I watch many welding videos but nothing comes close to yours for fully explaining how and why. Thank you so much for these incredible videos you present. Not only welding but watching a true and rare craftsman demonstrate his talents is a joy to watch.

[@Huskiedrive361]

Great video Karl! I've been a diesel mechanic for over 45 years doing maintenance welding of all kinds and learned more about proper mig technique in your 1 hour video than anywhere else. Really enjoy your channel and have recommended it to all my gear head friends. Keep the vids coming!

[@jdog_7027]

My opinion , Miller is a much better machine because it has more fine tuning than the Lincoln welder. One good thing is I see you push will mig welding. I have been welding well over 30 years. Nothing wrong with your techniques.

[@wrstew1272]

I agree completely. Taught welding in high school because my metal shop teacher was only versed with wood-? Just out of school went to work for a guy who had 5 semis and 3 bobtails that had homemade chaindrag systems to unload- then they weren’t commercially available, so we built and repaired everything in his dads farm shop. Stick was what was available, so everything was stick welding then. Later built mobile home frames, then got into helicopter and aircraft repair. Frames got me introduced to MIG, and the aircraft got me a tiny bit of TIG experience. But this is a youngster who has all this knowledge and gives it away for the world, suggesting that a click is sufficient in payment. What a wonderful time to be here!

[@ScruffieWilliamsburg]

Best mig tutorial I've ever seen. You explain things in a way that even I could understand and that's saying something! Well done Sir!

[@drumminjeff71]

Excellent videos! I feel like I'm learning more in 30 minutes than I would in 3 months of taking classes. Thanks man!

[@carenbarnet378]

This was the best welding tutorial I have watched so far. My skill level is hobbyist at best. About a year ago I bought an EMAX 165E MIG/STICK miniwelder. Stick max is 2.5mm I use satincraft reasonably successfully. However learning to mig weld was pigeon poo. Watching your video, I GET were I'm going wrong. You have explained so thoroughly, and will give me the confidence to improve. I wear multifocal glasses and seeing my puddle has always been my weakest aspect, Along with a TBI from being severely rear-ended 11 yrs ago. Getting in to a comfortable position, and stamina to continue is where i have to go slower and pace myself. Even though i live in Australia, you will be my goto teacher. I now find that i learn better by watching, rather than just being told how to... Thankyou

[@mattv4690]

Would be interesting to see a cross section cut of the first piece that you welded after getting the settings dialed in to compare the penetration of push/pull/whip and pause/straight. Thanks for the tips

[@brockwhite2360]

First time I've ever left a comment on a KZbin video. Great job Karl, if only I payed attention in school like I do to your video's. You've got the best voice for teaching, smooth and precise. I've just retired and now trying to learn to weld, once I saw one of your video's I turned off the welder and started to pay attention to someone who could actually teach me how to weld. Thanks, I don't think I have time to learn to weld like you but if I do, I'll send you a photo of it. Cheers, Appreciate your lessons

[@JosephDean-dy3ii]

as a never welded NOTHING in my life novice this has been the most instructional and well presented video that i have seen yet i give you 10 thumbs up I am trying to build a VW trike can't afford a professional to weld for me so beings that i have a small lincoln 135 I am going to try this myself THANKS again for the really great video

I know this is an old video. But you have a real gift of teaching…. If you don’t already, you should be getting to or have the neighborhood High School shop kids to teach them your skills. Invite them to your shop or go to the high school and help educate them in your skills…. I wish I had someone like you when I was in High School shop class!

[@comingtofull-ageinchrist6736]

I completely agree on the vertical welding. If you are angled up, it's going to be a bulky mess. If you angle downward, your weld is going to be more uniform and beautiful. excellent tips, Karl, thanks! Man, I haven't thought of this stuff in so long, I'm really enjoying the walk through on mig welding!

[@kiloyardstare]

I really appreciate you covering the REAL basics other videos seem to skip!

[@lukejackson4073]

As somebody who's looking to try out welding for the first time, even the first 20 minutes of this video do more than a lot of other guides you can find. Most tell you to find the best settings for your machine but don't actually guide you on doing it which led me to put my project ideas involving welding to the side, ready to tackle them head on now 😎 thanks again Karl

What impressed me the most was, your using the cheapest most basic welder out there and getting such awesome results! Very impressive!

[@boogiewoogiebubbleboy2877]

I like your videos because you explain in great detail with every step what you hope to achieve. You also show mistakes you make along the way, unlike others, who edit their videos without fault as if they were perfect. Here in the UK there are not so many restoring or building cars where I can learn from. I've watched many videos containing welding, and I think your welds are the cleanest I've seen. I'm new to this style of welding, so I took your advice from one of your previous videos and purchased the Lincoln 200. I got it as a deal package, which came with a mask, a pair of gloves, verious tips, and two reels of different gage wires. I took early retirement because of health reasons and to occupy my time, I decided to restore vintage cars, which are my passion. This is how I came across your channel almost a year ago. You are a good teacher and great entertainer. Thanks from a pupil across the pond. Keep up the good work, oh and by the way. What's happening about your partners car? She's been waiting for you to finish it a long time now. Sorry, I forgot her name.

[@lcar9871]

Have you found Trev's Blog" on KZbin? Trevor Hatton is in the UK too. His video output seems to have slowed a lot since Covid, but there's a lot of good restoration and metal working content in his older vids. Who knows, you guys might be neighbors!

[@daviddaniels6469]

Very informative. You really are a great welder. I am 69 and took a year of welding at a Community College when I was 21 after serving 2 years in the Marines. Our instructor was an old gentleman who welded ships in WWII . We learned stick, mig, and a little tig. You have a natural talent for instructing as well. I have a 1964 C10 that I am still replacing floor pans and other body repairs. 327 5 speed Tremec QA1 4 wheel disc step side. Great work .

[@RichardMazotti]

Karl your presentations are excellent with professional filming. Your lessons are organized, delivered with a smile, perfect pace, modeling, and control of the English language. Your knowledge and welding experience shines throughout each lesson. Your welding teacher should also be thanked for passing on his skills and motivating you to become a professional welder and teacher. I would encourage you, when the time is right, to look into teaching a class at a trade school, community college, or university. I am sure there are students who would love to have you as their instructor.

Now sorry for the ramble, I started to write you to mention, I just watched your video on beginners Tig welding and just wanted to add I often find with quite a bit of welding of all kinds when welding towards the direction I'm travelling it helps everything run more smoothly because im pre heating what your welding as i go, by pushing towards where I'm about to weld, thank you very kindly again, I am totally grateful and blessed for all the knowledge and inspiration you have given me, your a legend, cheers Ace

[@psmola101]

Outstanding. I'm in my 70's and just learning to weld - damn this is not easy with these older eyes - but your vids are the best I have watched, and I have watched many videos. My challenges are stickout and travel speed. This video gives me some real insights on how to control travel speed. Also my vertical welds are embarrassing - hope to try your technique tomorrow on a project I am in the middle of (trailer ramp/gate). Thanks for taking the time to pass along your skills - it really is appreciated.

My training at Oklahoma State Tech began with gas welding sheet metal. They said if you can do that, you can adapt to welding anything. I've found that to be true. Your teaching here is excellent. You've made me a better welder. Now, go cut that die apart and weld it back together with the opposite sides always adding up to seven. 6-1, 5-2, 4-3. Or, you'll get in trouble in Vegas. ;-)

Smooth talking Carl which makes for a good teacher. I noticed there were no edits (that I could detect) and you seem to have the gift of the gab. I absolutely love the bit about how you create fillets and you would know, when you can do that, you are a pretty good welder. Loving this video so far...stopped to tell you how much I'm enjoying it AND I am even less than a novice .. my new welder arrived yesty but they sent the wrong model so I have to wait a few more days yet. Thanks for your video. Believe me, it is extremely helpful to us plebs. Oh, last thing. You and your older welder shows me that it's the man holding the torch not the welder (within bounds) that determine good welding.

I’m 62 and I just bought a Century wire feed welder with a gas bottle. I do not know how to weld and I have watched your videos hoping I can learn something about set up and welding techniques from you. I’m going to give it a try this week since I am on vacation from work. I want to learn to weld body panels. I have a 1959 Chevy Fleetside truck the needs some panel patches welded to replace a couple of cancer spots. I will comment after I give it a go to see if I learned anything from your videos. Angel

I think it's the best guide for MIG beginners. Thx. ❤

[@joseserrano7950]

Dude, I tried everything on this video, and I must say it is the most informative and comprehensive video I've seen on mig welding. I learned the haft circle push method. After trying your method inotice, not only was I quicker on my welding, but I had clean legs. Beautiful welds now, I only use half circles when I have to do a lot of filling. Whip and pause is the way to go.Thanks!

[@juddmuterspaw4081]

You can seriously weld! I learned a ton! I’m just a self taught hobbyist, I’ve recently bought a new to me welder that is much higher quality and my welding is looking much better. Thanks for the video! Great work!

[@markmccoy8304]

Great tutorial Karl. I agree that the sound is one of the best tools a welder can use to get their weld correct. Back in the day, these used to be called "Buzz Boxes", because when the heat and wire speed were correct, you would hear a nice buzz coming from your weld. Of course there are other indicators that the welder must also observe and consider, but the sound was always the best for me. Keep up the great work Karl.
