The question that was originally asked about this, was the simple and common query: " am thinking of buying a 140 {110V GMAW}.....need to know if it will be able to do small aluminium welding jobs?? "
Given the fact that this is obviously coming from a hobbyist/beginner, my response was, not if you want aluminum welds with good fusion and low porosity, since I have never seen spray transfer achieved continuously by any of these machines. Then, I noticed the proliferation of spool gun connections and switches on newer 110V GMAWs, and thought that there may have been some sort of electronic break-through that made spray-transfer aluminum welding common on these machines. I am now convinced that this has not happened, and the comments of Frank, Al, and Lawrence reinforce this,
I think, still, to anyone who requires aluminum welding with structural integrity in GMAW, is to buy as Frank recommends, or, if production is not an issue, purchase one of the many cheaper AC/DC GTAW machines that will do everything well, but slowly.
I am still looking for a single video of a 110V GMAW machine welding aluminum in spray-transfer. Let me know if you run across any!
These machines are great for most light duty purposes, and a spool-gun-capable machine is even better, but quality aluminum welding is not one of their capabilities.
