Somewhere around two 47,000- 97,000 uf electrolytic capacitors. Screw tops are preferred as it would simplify installation but not absolutely necessary.

patrickh99, I have considered liquid cooling but the welder has to be kept as light as I can get it. The welder frequently goes up ladders and scaffolding in my hands.

My test equipment shows this 40 volt 59,000 uf capacitor at 34,000 uf, which is out of range. I'm going to get another capacitor. There's small difference between the before and after sine wave. It...

HF welders also don't have the electronics Lincoln's and Miller's do. It's just a cheap welder that's light enough to climb ladders and scaffolding in hand. I do prefer the old Ideal Arc welders...

Thanks Oil Pan. That confirms what I was thinking. Cooling depends on how fast the welder transformer can dissipate heat. I2R almost always = heat. That's key no matter what size it is.

I'm not aware of any water cooled welders. It's possible though. Water and electricity usually doesn't mix unless there are special provisions made. If I were going down that path, I'd try submerging...

I was surprised too. There is a lot of iron that holds heat in the transformer and inductor.
The 'slots' in the heatsinks are parallel to the airflow from the fan and the fin height was tall as I...

elozio32,
I did leave the rebar out of the post. That's a very important part. When I pored the stem wall, I put a bunch of rebar and left enough out sticking out of concrete to weld to the...

You could easily feed two 6 volt golf cart batteries in series with an 85 watt module. I would buy a quality charge controller to turn off the panels and prevent overcharge.

If you have any GFI or arc fault plugs, check those out. The GFCI's have given me problems thats hard to trace. Replace them or take them out of the circuit.

You should not get any voltage on a solar panel from only touching one lead (+ or -) to ground unless it's grounded somewhere. I do check this because I don't want there to be any voltage. If there...

For a floor 1 inch thick, I would reconsider using 3/8 rebar. As a rule of thumb, rebar will need concrete 3/8 thick surrounding it, which is more than 1 inch. You could use 6x6 remesh in flat...
