Back on subj. would be good.

you "can" weld with a teflon guide inside your mig gun, and if your doing it just to complete a home welding project, then its acceptable I think. If your production welding aluminum, the cost of a spool gun offsets the loss of materials and man hours wasted on trying work with aluminum and a standard Mig setup.

LateApex. That peice was done as a fitment/volume test peice in a friends Garage.
So, I had to sew it up freehand, and standing up. Without any jigging tools whatsoever. So, what you are seeing is my tack-points. after the assy was tacked, i just went back and closed everything up airtight (for the volume testing). Also, that pic was taken "as welded", no cleanup postweld.
