Ok, so heres the jazz;
I own a transmig 175i, and a tig welding extension.
I want to do some fine/light/small welding on aluminium which requires AC
The reason AC is needed is because, ac prevents oxidation building around the immediate arc area, aka where it counts. DC however is apparently like trying to solder on oxidized copper without flux.
I want to use some sort of an H-Bridge setup with heavy duty transistors or if possible/practical, (mos)fets, to turn my roughly 17vdc at the recommended amperage, to reverse rectified AC, aka, square wave, for the function of making it possible to weld aluminium to some degree not attainable with DC
As for the actual welds themselves, it will be very light duty, on small parts, models, custom heatsinks and such. Ill be using an innoculation chamber (mycology) to maintain an oxygen free environment to the best of my powers,
Im not sure exactly on the required amperage, but it certainly wont be a full 170A, thats for sure.
Ive seen these sorts of welds done before what i have in mind, on dc, open air (normal welding), on DC, on aluminium, for the exact same purposes, welding model car chasis parts on and some other weird blocky things i didnt quite recognize as stuff.
Anyway, point being, its already possible, but i want to turn the dc to ac regardless for better welds. Otherwise ill have to make do with dc.
So, what i want to know is, is it possible? Ill be working in short bursts so temp management is already taken into consideration. But is it practical, given that the idea of spending thousands on another welder to do an unjustifyably small amount of work, is out the logic window. Furthermore these arent 100% neccesary jobs but if it all works out, ill be able to start some new projects prior to winning bags of money to toss willy nilly.
Asuming simple rectification is not practical what would i need to do?
Also consider that im not looking for anything fancy, just basic enough that utilizes the cleaning phases cleaning properties during the welding, making it better/easier. In my mind simple rectification at a low frequency should do but i dont know, hence why im asking here.
