Build a Microwave Transformer Homemade Stick/Arc Welder

Step 12 Other Welders

Folks have sent me a few photos and videos of welders they've built off of this instructable. I want you to be able to see them too, so here they are!

Here's a video I got from Paul du Buf, of the Netherlands (nice case, Paul!)

Hey there, here's my welder based on your instructabletion. It outputs 35.5v, because the transformers were a little smaller than yours I think (couldn't wind a single more turn). So far I have managed to lay down gobs of metal on various steel objects in my garage, but I still suckat welding. Luckily I rented a nice welding video from Smartflix that had good reviews, hopefully that'll give me some insight into the process. I did manage to lay down a 1" bead though! The whole thing is going into a tacklebox housing.Props for a great instructable. Thanks for it!

Heres another one, same basic welder, but its housed in a .50 cal ammo can. Looks pretty sweet. Its relay controlled ( two 15 amp HVAC control board relays wired in parallel) , I measured 24 volts ac across the output wires.its also sorta heavy, 30 pounds.

at The risk of sounding "Lekker" Daft in South africa our elec is at a minimum of 220 volts. how would this affect the build? and how would i need to adapt the plans to accommedate for this.

[microedit]

number of secondary windings is affected....there is a formula or use meter to get correct voltage

Shouldn't be a problem but he says it on step 5. Aus has 240v and its working okay for me but I'm still on one MoT.

oh and also would it be possible to submerge this whole build into a mineral oil for cooling?

I really like the clean look but one problem, no way to get any cooling, no vents or fan
