What Am I Doing Wrong?
Hi
I'm a complete beginner. I have tried turning the wire speed up and down as well as the power but the welds still come out like these photos. Can anyone explain what I'm doing wrong. I'm using 2mm mild steel to practice the welds on.
Welder: Wolf MIG 140 Welder Gas/No Gas Combination Turbo, Smooth DC
30 amps-135 amps welding current range
CO2 gas cylinder
Wire: Mild Steel Mig Wire Welding Spool Reel 0.6mm 0.7kg Gas Welder Presision Wound
Any help would be appreciated.
Thanks Fred

Do you have gas on ? or polarity set wrong?

Re: What Am I Doing Wrong?
What sort of gas flow rate are you using? Should be either cubic feet per hour, or liters per hour.
You will also want to check that the work clamp is negative, and the wire feed is positive.
Check out my bench vise website:

Re: What Am I Doing Wrong?
newbiewelder,
when trying to figure out what you're doing wrong, it is best to describe each welding attempt as a discrete event; IOW when you ran one particular bead, you did not vary the wirefeed speed nor the voltage during that attempt, therefore only used one WFS, and one Voltage set, and contact tip to work distance. If you describe each attempt this way as individual discrete events, it will make troubleshooting easier because then these items could be ruled-out or investigated. Pics of your machine and wire/cable connections will also help.

Says he is using 2mm mild steel but it sure looks like stainless to me!

A couple of years ago I was testing an old Lincoln Weld Pack 100 on 14ga square tubing for reference purpose and made this test piece which I labeled and still have

Re: What Am I Doing Wrong?
yeah, looks like no gas coverage or very little.
