You're not comparing the same things.

In a typical circuit, voltage drives amperage through a resistance. The more voltage you have for the fixed resistance, the more amperage you can push through it.

In a transformer, you are taking the available AC voltage and transforming...

Agree with #2.

Also, every thread here is 'I need help.' Please edit the thread title to include your actual question so we can identify the thread later. Thanks!

This completely depends on your skill level, but it will be MUCH easier with the GMAW (MIG) process. It will also be easier if you load it with .023-.025" wire instead of .030".

Despite being the longest member here, my post was flagged for spam because I used the Edit button too much to fix typos and stuff. Here it is again:

The voltage rating on the receptacle or plug is just a maximum that it's rated for. The configuration of a "250V" device is correct for very common 208V or 240V actual applications.

Flexible metallic conduit is an acceptable ground conductor up to 6' in length. Rigid conduit or...

I've gotten it a few times at the end of a weld, and just assumed it was because I was using a machine with no post-flow and the still-molten puddle was reacting to lack of shielding gas at the very end.

Depending on how heavy it is and what you are doing with it, it may not even need to be attached.

I doubt I would have even thought of trying it with pulse. But I'm not in a production environment, either.

[MAC702]

That was my first thought.

How flat do you need it, at what budget?...

[MAC702]

Don't care what Ryan says. We need testing.

If you could dedicate the dryer receptacle to the welding machine, and not have to also have it available for the dryer, you could replace its 30A circuit breaker with a 50A (and maybe even a 60A) and it would be perfectly safe and legal. The welding machines have a duty cycle that allows this because...

Feeds better and anodizes better, but doesn't weld as easily as 4043.

Can you post some pics of what you've welded with it, and what Al alloy wire? How long have you been using this set-up (through how many spools of wire)?...

Yeah, sometimes you really do just have to pony up the ransom to the place holding you hostage. Sucks.
