Greetings, total Noob here with a question. I'm welding some 1/8" steel "skids" on to a snow blower using a Lincoln Pro Mig 135. I'm using a 75/25 Argon/Carbon Dioxide mix with a flow rate of 20 SCFH, a voltage setting of "D" (Highest on this unit) and a feed rate of 4 on .30 wire. I'm getting a lot of "blobs" and popping but not the smooth seam I'd like. How many things am I doing wrong? Thanks for your input and advice in advance.
