I live on a boat with a 24V LiFePO4 battery system that has a large capacity and discharge capability, but I don't have a large inverter for using AC gear.
I have a MIG welder, that takes AC and transforms it to direct current electrode positive or DCEP for welding aluminum.
I would like to cut out the mechanism that does the transformation (transformer???) and power it directly from my batteries.
Is that possible?
How do I do it? My gut tells me to look for the biggest wire after the big heavy looking thing "transformer" and connect the positive terminal of the battery to it, and the ground clamp to the negative of the battery and it should just work, but the unit has a display, and wire feed motor and a whole bunch of circuit boards sooooo maybe I'm crazy to just try that.
