New Camera Too...

[hankj]

Well, I figured a new MM210 owner without a digital camera would be in a bad bragging position, so I found one at Target for 80 bucks!

Here's my baby...

One pic deserves another. Here is a pic of my Hobart and battery charger/CV power supply for the Miller and Lincoln feeders.

Mike,

That "battery charger" looks suspiciously like an old telephone power plant rectifier/charger.

LOL, you are probably right. It is even electronically regulated.

If it's an old Lorain unit, I might even still have the drawings for it. I've got a lot of that junk still - never got around to throwing it away, and every couple of years, it comes in handy! See if you can find a brand name on it.

Hank, it is an ITT. I have the manual for it. It has a circuit that made the current ramp up slowly. I disabled that. It is rated at 100 amps, 26 volts. I adjusted the current limiter to 150 amps and gave it a test run, the smoke didn't come out. It has 300 amp diodes. I connect the wire feeder gun to the contactor coil circuit in the rectifier. It's unusual, but it works.

Those things ran 24/7/365 for twnety years in service in battery plants without a belch. 100% duty cycle. Your unit would have been part of a
-24V plant, which could have loads on it in the hundreds of amps. They used a bunch of these in parallel to keep the batteries floated.

Long time ago...
