I'm using Tri_Mix gas at 20 CFM and .023 wire. I'm using 17.5 volts and 150 FPM for 22ga. I'm burning the wire down to the tip, at times, and only intermittently getting a good ark. Getting a lot of popping and my welds have a brown soot on them.
The 252 goes down to 22ga. mild steel, I've noticed some of the smaller MIGs go down to 24ga. Would they be a better choice?
Is what I'm trying to do possible and practical?
Any help or suggestions would be appreciated, thanks!
