IMHO, thick aluminium is OK fed up the whole torch cable, but you should keep a separate liner for doing this. Thin aluminium is easier if you switch to TIG Spool-on-gun feed is fine, but they're expensive and IMHO only for bulk fabrication in thin stuff.

To be fair to it, that picture looks like a gasless set running at too low a voltage, possible with gas wire (the wire is melting, but there's no penetration of the base metal). It's not quite the classic globular transfer.

I've made yards of railings, ornate gates, and loads of old tractor,dumper/whatever repairs etc ALL with CO2.... Cheers Jim K |
