I have a minor quible about hooking the 110 fan to the neutral. In this
case it IS neutral, newer machines will have the third wire as ground.

And i'd agree some other posters, looks like the airflow is a bit
marginal. You want LOTS of air on the core, even when the fan gets the
usual collection of leaves, dust, cobwebs, and oat pollen.

actually, I just installed an old computer fan in there, because the
original "gave up the ghost" after only 23 years of service. and because
I had a dozen of those big ol' 115 volt AC computer fans sitting around
doing nothing. you can SEE this project, illustrated in it's full glory, at

call me a space cadet, but that's what I did... :-). I also considered
cutting a big square opening into the case rear, and installing a big
squirrel cage blower sticking OUT the back of the welder, but decided I
didn't want to "kill" the shop space, or mangle-up my 'fairly new'
welder that much...yet

have a nice day,
