I turned my AC stick welder into a DC welder with only bridge rectifiers!
Has anyone tried it?

OH! You can overclock those welders for free!! I had one of those welders years ago. Well, a very similar rebadged version of that welder. There were two versions, a big one and a little one (they looked identical, but one had more amps). Turns out the good welder and the lesser model are the exact same welder, and you can easily unlock the extra amps.

I was a broke high school student I couldn't afford the good one, so I had to buy the poverty version. There's a plate that decouples the primary from the secondary which you operate by turning the handwheel. That's how you adjust the amps. There are two sets of holes to mount the transformer, and one set of holes won't let you pull the decoupling plate out all the way. That artificially limits the maximum amps. Just unbolt the transformer then reinstall it on the other set of holes. Congrats. You just gave yourself an extra 30 amps.

I think there's a 150 and a 180. Anyway check the bottom. See if there's an extra set of holes in the sheet metal for the transformer. You might be able to upgrade this welder even further.

waooo, that's quite promising.
I guess this can be put externally if I want to try it without being intrusive to the welder ?

Shouldn't be a problem.

A friend of mine down in dry gulch Tx. sent me a DC converter for my Lincoln 225. It was a nice self-contained unit that could be mounted on the top of the machine I connected it one day to see how it worked, which was great someday though I want to remove it from its case and install it inside and add the connectors to the front of the machine so I can have either AC or DC by simply changing the leads' location

I'm glad you guys like the project.

The most effective change that I've noticed is the amount of the metal that melts from the stick and thus the thickness of the weld bead.
As far as I know, with DC current, electrons move more easily from the stick to the base metal.

To nova_robotics:
I am willing to try this hint of yours, do you think the welder (cables especially) would stand that higher current? 30 Amps more don't seem too much for the cables, actually.

To Christophe Mineau:
Sure you can put it externally. Since the output coil it's directly connected to the cables I guess you want to mount it right before the cables to avoid the soldiering part and stuff, right?

To Frank S:
What were the results, what change did you see in the welding?

Mine ran fine for about 10 years until I gave it away to my brother-in-law. It's a free 30 amps. If you get nervous you can always adjust it down with the handwheel.

Hi, It's just to give it a try before cutting the wires, if satisfied, I could put it internally just like you, I'm not afraid with the soldiering
