Ideally about 10mm steel bar. Wasn't sure if id be best with MMA or weld from both sides with TIG .depends on the prep you do and the passes you run. how thick do you need to weld?
and slow turns into expensive , you can empty a gas bottle very quickly when you start to get to the limits performance wise ,,with MMA it's more a question of how big a rod you can run... when running nicely, you just stack beads to get the weld size you need.
You could run 3.2mm rods at around 100 amps or less, stack 3 beads and it would probably give you a good throat size.
I'd say your machine would be happy running up to 4mm rods at 150 ish amps, yes the paper specs say it can do 200 amps MMA, but in reality I'd be dubious of that claim, it takes a lot of power to do that.
You could do it multi run TIG also, but it will be slow!
I don't understand why is it multiple passes on MMA and TIG are considered ok for thicker steel but not on migYou could do it multi run TIG
That is good to hear!I have got one of those stealths,
They will run a 4mm rod at 160a with no problem at all.
Because with MIG you're laying metal down constantly, and with MIG the energy has to be enough to melt the filler, and the base metal, whilst travelling fast enough to avoid piling up metal. It's a delicate balance between voltage, wirespeed/amperage, travel speed, arc length, and how much metal needs to be melted at any one point.I don't understand why is it multiple passes on MMA and TIG are considered ok for thicker steel but not on mig

ET has a good explanation alsoThanks for taking the time to explain
I think I get TIG from the explanation as the heat can go in independently of the filler but...
stick has to melt the filler and the base metal and still travel at the right speed for the job. If you don't keep feeding the stick down then the arc will get longer and eventually stop so I don't understand why, from a physics perspective, that would be any different from mig especially once you get up to higher wire sizes. They seem fundamentally similar processes albeit with a longer "stick" on the mig
