Actually… I’m right and wrong. Assuming you’re refering to TIG welding. Then I’m right. Assuming you’re refering to MIG, Flux, or stick. It CAN be right. I hardly ever use a wire fed type welder anymore… To boring. I’m all TIG. So all I think about are TIG set-ups. So that’s my bad. I often forget about the differences. 200amps on a MIG, Flux, or stick isn’t overly hot. But, it’s still hotter than what it should be. TIG welding put 70% of the heat into the work piece. Then 30% into the Tungsten (electrode). All the others are opposite. 70% heat into the electrode. 30% into the work piece. On a 3/8’’ thick plate on a MIG with .035 wire. You should be at about 24-ish volts and about 220-230ish amps… so on a 1/4’’ thick it would be less. Around 180-200a. So again, I apologize. I’m right and I’m wrong. --- _[View the full topic](https://forums.speedlife.net/t/custom-lower-control-arms/115777)._
