I'm female and don't need to know this welding stuff but I often saw my father and men welding with all this flashing stuff and wondered what the MIG welding they said they were doing involved. I thought there was just one kind and had no idea about types of wire,gases,machines involved. 5his guy is pretty knowledgeable about MiG welding and very practical, "hands on". I learned something new here. In case I ever need to know about MIG welding. To add to my mental stash of interesting "miscellaneous information".

[@melgross]

Being female doesn’t mean that you don’t have to know about this. Being uninterested has everything to do with it. There are many female welders and fabricators.

Man I was already stoked to learn how to weld and after watching your videos, It all makes sense and only strengthens my faith in my decision. Thank you for all of this!!!

[@campbellpaul]

Wow! That dual shield makes a sexy weld (looks like E7018 for wire feed). Thanks for clarifying all this Tim!

[@AlpacaRenee]

I didn’t know there was an application for flux core with shielding gas. Great, informative video. Thank you

[@dravencastaneda]

I hated self shielded at first, but as i got to get more practice and arc time i started to really like it. My teacher told me you could tune your machine so that you can rock a stick out of like 3 or 4 inches. You want 10-15 degrees of drag, keeping your wire in the flux as you pull the puddle forward. My biggest problem starting out was not waiting for the puddle and flux to establish and not allowing the flux "c" or "eye" to wrap around the puddle as you end your weld. Also this might not mean anything, due to the way the electrons flow, when i was dialed in, i could see 2 tiny beads of flux "dancing" or "spinning" on the end of the wire

[@campbellpaul]

That's very good information. I would recommend now that you stop watching the arc, though, and maybe work your way to a 12 shade (because you just need to see the puddle's edge). You'll save your eyes and learn to "walk around the house in the dark".

[@dravencastaneda]

@@campbellpaul I run shade 11 already, just something I noted in my initial start,been welding for 3 years, I've definitely had to talk people into switching from 9 to anything higher.

[@MrFrankwhite357]

Hi Tim, I really like your teaching videos. Can you recommend a combo welding machine for a beginner looking to weld a trailer frame eventually using a MIG welder and the size wire needed?

[@johnmacmillan627]

Hi Tim, enjoyed your course. Have a question that I am unable to find an answer to. I have been looking to buy a pulsed mig welder, not the very expensive ones , such as a yeswelder double pulsed mig welder. It says that it uses spray transfer mode. Now how does it do this when welding thin material if the voltage and amps must be high to produce a spray transfer? Wouldnt such settings blow a whole in thin aluminum almost immediately even on pulse? Hard to get a handle on this

[@soulsharts]

Idk if he mentioned it, but with self-shielded FCAW, the electric current is ran as DC electrode negative (straight polarity), meaning you want your ground wire on the positive terminal and your electrode on the negative terminal. If you don't do this, you'll have a terrible time and your welds will be absolute trash.

[@aziznuhu3151]

Good job

[@TimWelds]

Thanks!

[@ChallengedCustoms]

I am hearing that the brand of flux core wire makes a big difference on how much slag will be lifting off compared to chipping it off with the hammer. Which brand of flux core do you recommend for almost hassle free welding?

[@andresdastolfo2695]

Hello how are you? Nice video. I have a flux core machine using a 0.8 wire but the roller is 0.9. Every time I try to solder something, the amount of spatter is too much. When welding with flux core without gas, is continuous or alternating electricity used? Cheers from Argentina

[@cpcoark]

Could you cover dual shield welding a bit more. Is the flux core wire a special type? Minimum current required? C25 or special gas? etc

[@TimWelds]

I do have a video on the channel covering a lot of the details and I can do some more videos on it in the future. The wire is different from self shielded flux core. ESAB calls it Dual Shield wire and Lincoln calls it Outershield. It usually uses C25 gas.

[@petrospapaioannou2036]

I have a question. Which welding mode gives joints that are more tolerant or elastic to compensate heat expansion and contraction ? Stick or mig ?

[@ZILAwelds]

Stick or dual shield

[@kingmouse9292]

So if I take your online courses, will I be able to get a welding job? I’m a stay at home dad at the moment, so I don’t have enough time to go to a college/school. Any help is appreciated

[@nanaklif4973]

Big ups tims❤

[@TimWelds]

Thank you!

[@jaymichael91]

I have an adjustable welding helmet and still can't see my weld during operation. I can only see the arc. Is there a good goto helmet that beats all?

[@TimWelds]

As long as it has new covers on the inside and out, most brands work well. Part of seeing the weld puddle is practice, though a lot of the new helmet models are much better. The thing to look for is an optical clarity rating of 1/1/1/1 or 1/1/1/2. I personally use a Miller digital infinity and I like it. It has a little weight to the lens, causing it to shift around a when I’m sideways under a car. For bench work, it’s great. I’ve demoed several brands, both cheap and expensive, and as long as they have that clarity rating, most of them are fairly similar to look through, leaving build quality and fit preferences to differentiate them.

[@asintonic]

Hmmm im surprised you dont use or have a miller mig welder!?🤷‍♂️. Thanks for sharing

[@TimWelds]

Thanks! I have Miller machines as well, in fact that’s what most of my videos are made with. My Miller MIG doesn’t have pulse, so the HTP was a better fit for this video with its more advanced capability. This particular machine is a new model that they sent me to make a set of video manuals for their website, so I’m also giving it a good test while I’m at it.

What about Pulsed Flux Core welding? How would that work?

That is nor a thing. Pulsed metal cored would be a thing

[@alshipley6999]

So i have been running 75% argon an 25% oxygen an i follow the chart for my settings but the wire comes out smoothly for about 4 seconds then it holds for a second or two then goes another 4 smoothly. What could that be?

[@TimWelds]

It’s likely that the spool brake is too tight and the drive roll idler is too loose. This will cause the spool to jam and the drive roll to spin. You’ll be able to see this with the lid open shooting some wire into the air. Also, double check that you’re using the right size drive roll. The last thing that it could be is the gun liner, but based on your description, that’s less likely.

[@JHizzleinthebizzlePNW]

I appreciate your video's. I do always wonder how much money you make 😅

[@cbmech2563]

Working on trash trucks it's been my experience that flux core is not nearly as critical on clean metal

[@fladoodel]

Flux core will weld anything. I've welded painted steel together before with flux core 😂 same thing with stick

[@cbmech2563]

@@fladoodel truth. My actual preference is 7018. Sticking trash trucks back together? I sometimes wonder how many hundred pounds of it I've burned over the years

[@4speed3pedals]

Does dual shield penetrate better? or more consistently? It is a smooth finish you achieved with little spatter, I like it. Just wondering if it is worth getting involved with. Be nice to see the different welds cut and etched to see the actual depth of weld penetration.

[@TimWelds]

Each process can penetrate sufficiently when done right. I’ve taken dual shield cross sections with great penetration and some with lack of fusion too. It comes down to developing an adequate procedure for a particular application no matter the process. I would say that it’s generally better than short arc on thicker material, but not a silver bullet. I’ve reviewed thousands of cross sections from all sorts of welding processes and there is a ton of variation within a given process, so comparing two processes based on a few samples can be misleading. That being said, it would be an interesting experiment and video, so I may take a shot at it. If you’re working with heavier material, looking for better toughness or welding out of position, it’s definitely worth considering.

[@ZILAwelds]

the dual shield especially when using 75/25 gas vs 100%co2 is a spray transfer, it is very hot and "washes" and penetrates MUCH deeper than a lot of other welding processes. The slag system allows it to be run out of position and it also "covers" the welds so the ambient air can not rush in and harden the weld .... that way typically not only the penetration is better but also the ductility (elongation) is much better than with sold wires that lack that "cover" right after they are welded. this makes dual shield welds less hard, less brittle and better suitable for impact and high stress applications ... that could be an entire video by itself .....

[@mkearn724]

@@ZILAwelds I don’t think there could have been a better response. You nailed all the key elements and benefits all in one simple comment. Dual shield definitely has its place. I’ve been running .045 dual shield 6 days a week for about 3 months now, and it’s pretty amazing how much wire can be ran in a day

[@ZILAwelds]

@@mkearn724 yes, deposition rates with 045 are pretty good !!!! Wenn you weld s lot of inch or inches thick plate with reasonable good fit up and you have a 300+ amp machine and asbestos gloves …. You are through the first 33 lbs roll before lunch break 😂 It will cook your knuckles and bleach out all your clothing …. But it REALLY makes progress
