on that WRX exhaust was that 16Ga SS? if so 70-80amps is way too hot, try going down between 35-55amps. you might have to run slower, but you will get penetration.
We just lost the motor in one of our cars because of the oil pickup shearing off, but it sheared off at the bottom the tube was still attached. it looks like the motor was dropped on its pan from a forklift and they put a fresh pan on it to hide the damage. I will be welding the new pickup to be more sturdy.
Is that a Gas lenses your using or a normal cup? i used a #7 i think it is Gas lense for almost everything.
