This is Constant Voltage Square Wave vs Constant Current Square Wave with Lincolns controler.
I've recently started a job and am learning how to run their new SAWer. It was recently bought and no one here knows much about it(especially me who ain't even a welder). The Lincoln factory guy told us to run CV but my test strips which I cut and bent showed poor penatration and a lot of porosity. I tried CC today and it was much better. The test piece actually bend rather than break. So why CV over CC? What is to be gained with each? It seems to me that CC give me a way to increase the Current and therefore the penetration. This is what I thought I needed. With CV I could only increase the Balance between the = and - waves and also the amount of DC offset but can't get enought to get it right. I'm really going mostly blind here reading the books each night and learning as I go. My background is in maching which probably explains why they hired me to run a welding machine. We make tanks of 3/16 to 1/4 low carbon steel. 4 to 8 ft in diameter.
