Convert 115 v welder to 220v?

[Sberry]

First we want to convert it, now we are going to improve it.

[SidecarFlip]

Are we referring to Lucas electrics on the welder?

This problem is most-easily solved with a small rectangle of plastic printed with "Visa" or "Mastercard". Take same to your favorite LWS. The rest is obvious......

For the old-timers, it's like Moody/Moody II all over again. There are so many ways for this to go wrong, from electrical insulation failure in the transformer due to voltage punture or thermal stress, to really poor welding performance from mismatched capacitance and inductance, to the possibility of injury or death.

The only way I is to try...
Some concerns I have.
The voltage at the transformer would almost double! so that's from 28V to like 56 Volts! Not good.
The fan
The 24V that goes to the gun trigger
The motor speed
The difference in voltage between each voltage setting would be like night and day with only 4 selections.
The rectifier.... can it handle 220V?

So yeah.. there are some concerns.. but wit the right components it should be doable.

Indeed.

Of course it's doable since they already exist- fabricate one if you want, like you said.. only way is if you try.

M20, with the right components, it would have been a 220V welder already. Let's replace the fan and the primary transformer, maybe one or two other minor things. That means you just replaced about everything that is of value in there. Doubling the voltage should not peel the paint or wreck the insulation, which is good from an appearance and olfactory point of view. Unless you smoke the transformer varnish from too much heat ...

I do miss Moody. He could take more abuse than even the toughest brands of welding equipment. With a smile ...

M20 - you're not a reincarnation of Moody, are you?

Wonder whatever happened to Moody? Guess we'll have to do with Moody V2.0.

Then there was the wannabe engineering student with the aluminum-oxide jonboat h e l l bent on fixing it with a fluxcore welder. Wouldn't take no for an answer.

That was a fun thread to read.

That's kind of abrasive, don't you think ...

[Sberry]

I am with Broc, go for it. I wouldnt mind seeing this.

Stick to the 4th for your firework viewing, Safer!

Holy Mohs-es....no axe to grind here. I'll apologize if I caused anyone to grit their teeth.

Or how about the bright orange light in the sky, rather than the welding machine glowing..
I am glad this is what I seen in the sky 6:30 this morning and not one of my machines..
