Yeah when it does it you know it's right. I don't use a lot of atom arcs I had to test with some once and I Really did not like them. My favorite is a made by techniweld. They wash in good, the puddle is as clear as an Excalibur. They cost less and smell good when you weld. They smell like laundry detergent. They peel clean. The atom arc seemed to really overheat the slag and it sticks bad in the toes. I really prefer to stop and prep instead of " just turn it up a little", so I thought there was way I was burning too hot. Just not for me I guess.
