I already have a 160A MIG welder with a large spool of wire in it and I have three mini reels of wire but no filler rod apart from brazing rods. There is no electrical connection between the wire coming out of the nozzle, so it is basically just putting metal into the weld, just the same as feeding a rod in. I realise that DC makes ali welding difficult to impossible, but I can't afford an AC TIG welder.

Yes - I do realise the whole idea may be crap and I am desperate to get back into the workshop to try it.

One comment about MIG and TIG and Stick - the polarities are different I believe for different purposes.

Cheers,

Rob
