I've been meaning to ask this for a while. What is the best technique for welding thin steel to thick steel?
I have a 120V Hobart Handler 140 MIG (flux core) machine and a 250A DC stick welder but I tend to use the stick machine more often. I am completely self taught and do "ok" but needless to say I am a much better grinder than I am a welder. :-)
I always struggle when I have to join a thin piece of steel to a thicker piece of steel. If I set the amperage to get good penetration on the thick material then it wants to burn through the thin material. If I use lower amperage so I don't burn through the thin material then I don't get good penetration on the thicker material.
Any words on wisdom?
