View Full Version : tig welding suggestions
12-06-2004, 10:39 AM
I have an inexpensive chicago electric stick-tig ARC-180, It has a DC amp range of 25-110 amps and AC range of 47-140. I plan to fabricate chopper tanks and using 16 gauge sheet. My question is this welder has no foot peddle to regulate amperage. What would you suggest I set up with to start my test welds at?

Did it come with the TIG torch? If it didnt you need to get one with the hand control.
I suggest starting around 45-60Amps.

How would this arc-180 tig welder by Chicago Electric do on 18-20 gauge sheet metal, how about the chicago electric arc-130? I know they are inexpensive but can they do the job of patch panels and rust repair?

It should work fine. Even if you get a torch with the amp control knob on it, you still will not be able to control the amps on the machine. I don't believe it is a variable amp machine. I have my tig hooked up to my Lincoln welder. I weld some sheet metal with it (about 16 to 18 gauge) on its lowest setting, which it 30 or 35 amps. You just have to be careful and weld in short sections and remember to hammer and dolly when you can.
With the lower setting your machine has you should have no problem. It just takes a little pratice.
I would start at about 20 amps or soand go from there.
