After anyone who may be able to help with me. I have a parweld 202 and seems to be having an issue with the cleaning action side of the ac welding. (Electrode positive) Just seems to struggle with it and eventually will run into the bead. I can counter some of it by massively increasing argon lpm but it's not right. These Welds are the best it has done but were at 25lpm! I have checked for gas leaks which I cant find any, (regulator to machine, in the machine, or torch side) Thinking it may be down on power on electrode positive as welds fine on dc.
