The Difference Between DCEN and DCEP | TIG Time

[@edmundnyamupepema]

Thank you Mr Tig! I now have it crystal clear, DCEN and DCEP professionally explained 💯/💯

[@WilliamMcCormickJr]

I actually weld magnesium DC straight polarity. It makes for a killer weld. The puddle is sluggish however the strength and quality are very good. On very thick aluminum like one inch plate, I clean the aluminum up very well and I use DC straight polarity with a little Argon and a lot of helium cover gas and I get rather amazing results. It does not work well on thiner, or dirty aluminum. And it does have a learning curve. Some test pieces are required. You have to poke the puddle with the wire after you get a nice hot puddle. Let it burn in a bit and move on. Sincerely, William McCormick

[@WilliamMcCormickJr]

I also weld bronze or brass with DC as well. Sincerely, William McCormick

[@michaelsoler332]

I was working on aerospace,(blue origins)and they do use DCEP on Inconel but the tungsten never ball up. Do you you why does not ball up? Thanks

[@mikef-gi2dg]

I am planning on buying a mp machine and the majority have a dc neg tig feature, I had no idea what that gave or took away as far as tig feature goes. Mr TIG may have just cleaned that up for me. Thanks MR TIG.

[@mikef-gi2dg]

I purchased that MP machine, this video helped me understand the difference. I am a novice welder at best.

[@techninefan90]

@@mikef-gi2dg I want to get into TIG welding. How has it been going for you?

[@mikef-gi2dg]

@@techninefan90 I purchased a Lincoln le31-mp it has the basic scratch tig capability. I have yet to buy the torch set up....everything that has nothing to do with welding is getting in the way. I don't think my machine will do aluminum, that's what the spool gun ( also need to buy ) is for. I just want to try it in sheet metal and thin stuff. Hopefully really soon I can start to play. I am going to have to find a TIG 101 for beginners manual from somewhere. I'll update.

[@raykim1812]

Thanks for your video..I think the difference comes out from the direction of electron..So the material(connected with positive pole) hit by electron (comes out from negative pole) becomes high temperature..

Gettin learnt with Mr. Tig

[@NOOne-im5vg]

I have a Miller welding plant with separate power supply control unit, a dc hf tig unit and mig unit all externally linked. The thing is, when the tig unit is connected up with electrode negative, there is no hf so you have to use a scratch start, once the arc is struck, it totally destroys the tungsten. So it has to be connected with a reverse polarity. The set is not capable of running AC for aluminium.

[@zakaroonetwork777]

I’d like to see Mr. Tig Weld Aluminum with a Lincoln AC Buzz Box.

[@jeffgood6441]

Probably couldn't

[@lukaofthshire]

I've read an article and seen some pictures of smaw aluminium welds. But also DCEN aluminium weld using separate flux solution. Could you demo this technique and test its effectiveness? (the DCEN with flux)

[@nickpalmer5826]

RIP Mr Tig

[@seandrake7534]

I have a old century AC DC stick welder that I use to Tig weld steel with. Can I use the AC side to weld aluminum with out having high frequency so I can use argon instead of helium like you do on DC if so would it be ac+ or ac- Thanks and hope this makes sense

[@ypaulbrown]

Sean, if you use the AC side of your machine, the arc extinguish when going form + to -.....that is what the high frequency is for, to keep the arc going. hope this helps you, Paul

[@richardandres5266]

does aluminium stick rod works on ac welder?

[@SOLDOZER]

"Mr TIG" could never TIG weld worth a squirt.

[@sephangelo4603]

Where I'm from, everything is all about AC. In order to turn a generic AC buzz box into a DC welder, I'll need resistors with bridge rectifiers, but the problem is that I don't know where to get resistors.

[@mceperformance8978]

+Seph Angelo No resistors are required. Only a bridge rectifier is needed.(A large capacitor added to the DC output is not a bas idea either)

[@grege2383]

Dumb question here - so the torch is plugged into the positive or negative?

[@weldingjunkie]

greg E straight polarity so DC- for Tig if you’re doing stick it’s DC+

[@grege2383]

@@weldingjunkie - Thanks, it's been a while

[@crazyrufus09]

Somebody explain to me why the electrons flow from the base metal plate to the electode holder! Please my weld teacher is making me answer the question and I have no idea

[@mceperformance8978]

+Alex Sircus The electrons flow from the electrode TO the base metal (using straight polarity).

[@josephbrown1804]

..and from the base metal to the electrode in DCEP (reverse polarity)

[@joons3374]

simple physis, the machine is setup for stick welding

[@qigong1001]

Can someone answer why there were no visible fumes.. ?

[@WilliamMcCormickJr]

Because instead of the flux on the ARC welding rod, there is Argon inert coverage gas keeping the weld from oxidizing and the tungsten from oxidizing. Below are the original classifications for common welding procedures. They change them up now and then. I have been welding since I was 9 and I really do not bother with the new terminology. TIG (Tungsten Electrode, Inert, Gas}. ARC (Anode, Rectified, Cathode) MIG (Molten Electrode, Inert, Gas) MAG(Molten Electrode, Active, Gas) Sincerely, William McCormick

[@weldingjunkie]

Tig you can weld litterly inside your house if you wanted to. I wouldn’t but people do in thier laundry room

[@MetalMagoo]

@@weldingjunkie sometimes you have to borrow 220 from the dryer lol

[@kf8575]

@@weldingjunkie fumes are still produced from tig welding. Just a lower amount so not as visible.

[@bobl5335]

IT WOULD BE A BETTER VIDEO IF YOU PUT A FILTER LENS ON THE CAMERA TO SHOW WHAT YOU ARE EXPLAINING . I CAN'T SEE

[@dinanath6678]

I am yelmuniym tig and co2 mig and m s, ss weldar you bisa gibh

[@cdrom1070]

total fail on my part

[@cdrom1070]

mr tig I hope they pay you like 150$ an hour because I tried the other polarity (its picograms, should have used dmm) and the tungsten really started to melt. Basically I am saying this is process is hard as hell. 500 years later.... im convinced you can go to some of these 'tig welders' and upon close inspection you see the face comes off like a car hood and there is a beeping flashing computer and gears in there. think ima just stick to JB weld for the time being!
