Pic of my battery charger/mig welder

This is a 24 volt, 100 amp electronically regulated charger. It is rated continous duty with no fan. I plug in either the Lincoln or the Miller wire feeder.

I had to do a couple on minor mods. It had a walk in circuit to limit the current when it first comes on. I disabled it. It has 300 amp diodes. I re-calibrated the amp meter to read half the actual current.

I love the idea and the ingenuity. I can't figure out why you wanted to only read half the current, though. Maybe I'm overlooking something really obvious.

Hi Mac, actually I changed the meter calibration so if it reads 50 amps, the actual current is 100 amps.

But why?
Have you tweaked it so it'll put out more than 100 amps actual?

[Mike W]

Right, I tested it at 150 amps. I just needed to get the meter to read more then it's 100 amp full scale reading. The charger had a current limiting circuit circuit that I disabled.

that battery charger is a lot bigger than I had imagined !

It is a little heavy. I made a dolly setup so I can move it around in the back yard. I once had the Miller wire feeder winched up 12' in the air.
