Hi Hol,
that's a really neat welder! If you want to tune it up and make it work
better, you might want to replace the tube that the wire gets pushed
through. When it develops friction, the drive wheel can't push the wire
through reliably.
Fortunately the tube can be replaced with bicycle brake cable! Just get
some of the good stuff (teflon lined) from a bike shop, and razor off the
rubber coating so it fits in place of the original hose. The welder will
work better than new!
As for the flux-core wire, it is very dangerous to use that indoors,
because the flux is for preventing oxidation - and our lungs need to
oxidize! So it should never be used indoors (and using it outdoors will
require a shield so passersby don't see the arc)
At some point we should talk about making a ventilated corner of sudoroom,
where welding and other fume-producing tasks can take place. Hell, maybe
the Robot will be welding by then.

require a shield gas, just turn it on, clamp the ground to your work,
point and click. the wheel that drives the wire from the box through the
cable to the gun doesn't have very good traction, so check there if the
wire doesn't feed. the welder uses 17 amps so only use directly plugged
into an outlet (!!!)
bring steel! the antique saw actually works really well for cutting
stock down to size

New subject: welder in sudo room
was talking to david about trying to get some HVAC ducting at urban ore.
i bet they have a lot of big sections just sitting there needing a
little work and blowing the air up to one of the existing exhaust fans
in the ceiling. in the interim the cart (rolling chair w/ welder sitting
on it) could be rolled to the utility room and the box fan set at the
door for exhaust. thanks for remembering safety too, flux core wire is
almost as dirty burning as stick welding electrodes. What I'd really
like to do is find a longer sheath so the welding tip can be mounted on
an x-y table or of course arm. i didn't note the nature of all the parts
that came with it but did that arm come with its own welding power
supply?

New subject: welder in sudo room
The robot came with the wire feeder and even a giant BARREL of welding
wire:
http://spaz.org/~jake/pix/giantrobot2/IMG_20140728_185950.jpg
but the power supply was not at the place where the robot was. The guy I
got the robot from says he has the welding power supply somewhere else,
and implied that we can have it too, but he wants a 501c3 donation
receipt.
I intend to get it to him, and he said he would refund our money and give
us more stuff. In the meantime we could easily mount your MIG welder on
the robot and have it use that instead of its own original one.
here's what we had to do to get the robot to ALMOST move last night:
