Bob LaLonde - sorry lost your article / posting
You are using GTAW / TIG?
You could go for GMAW / MIG?
You'd need 200-and-something Amps and mid-20's volts
(* 240 25) ;; 6000 ;; about 6kW at the arc
Probably most of 12kW power draw into the machine.
Stops that idea at its inception?
The strong Ali-Mg 5000-series alloys are easy to use in a conventional
GMAW machine - but there's some set-up involved - change
* drive-rolls
* liner of hose to gun / torch
* contactor tip (that's nothing though)
Never used them, but - there are Ali "stick" rods.
Someone I met who has says they are monster things. For your
situation - few to do infrequently - might be the answer?
Reply on your thread and I'll pick-up there, but to be frank I think
that's all I can offer.
