Step 2Power Supply
Wirefeed welding on steel uses a DC constant-voltage power supply.
Lucky for us, that's exactly what a car battery is.
The range you want is between 18 volts and 36 Volts. I prefer 24 Volts for most of my welding.
Here's my power supply. It's two car batteries. They say "deep cycle" on them, but I don't think they really are. You don't need deep cycle batteries for this purpose anyway. Or even very good ones.
To get 18 volts, use three 6 volt golfcart batteries or a 12 volt battery and a 6 volt one in series.
To get 36 volts, use three 12 volt batteries in series, your whole golfcart worth of 6 volt batteries, etc. etc. You get the idea.
