A mig welding power source is consant voltage, a tig and arc power source is constant current. The voltage will stay within a couple of volts of the set point the amperage will change with the electrode stickout. your voltage will range from 0-23 or 24 with short circuit mig. that puts your amps to about 180 on the high end. If you get above that then you move into globular transfer then sprayed transfer both of which require different gas mixtures to work properly. your welder looks great and I love to see that kind of inginuity.

I think you have done an awesome job on the cheap!

The biggest project I pieced together "on the cheap" was a Cadillac trunk pulldown system from ebay on 2 seperate auctions for about $15.00 total!

I'm curious though...I'm a guy who likes to build stuff too, but really try to factor in that I feel my free time is at least worth as much as I make OTJ (really free time should be worth 2x of OTJ!)

How much time do you have so far into this nice example of a DIYWelder?

I got a brand new set of 5 600amp Diodes from ebay $10

I had to take some pictures of them haha,










The purple ones are the new ones,
The Red and white SCR's are my old rectifier bridge (2) of them are dead.

This means I can finally rebuild my welder to full power


The project lives on.

It has been an ongoing project for the past 3 years. total real time I would say about 15 or so hours invested.

"Mcguiverize" I like the sound of that.

It is like building up your own engine you get a great feeling knowing everything that is going on inside.

A great feeling the other day was welding up a coat rack I sat back and feel proud that I built a coat rack with a welder I had built ha-ha words canít describe that feeling.

Not to mention when I go into the store to buy wire the guy will ask for what welder I will smile and say it is home made after a bout of confusion a great conversation will always arise so a 5 min trip to get wire normally involves 30min of talking about it.

Yea man!

Post up some internal pics. It will have a high power generator inside of it to supply the power. easy fix would be to buy a AC motor that has the same HP /RPM as the gas engine and you would be back up and running. If not you will need to find a 'beefy' transformer to convert line voltage for you. any questions I am happy to help.

Very nice job!! I can see from the work that you have some sort of electrical or electronic background. Keep it up. I work as an industrial electrician/electronic tech, and I would just like to put out a small disclaimer to those that might want to try to duplicate this welder, be CAREFUL. What you don't know may hurt or kill you. This guy knows what he is doing and electricity is very unforgiving, so make sure if you are going to try this you either have guidance or know what you're doing.

I'm impressed with the welder, VERY COOL.
