Adding a spool gun to mig.

[Gadgeteer]

This is my method of adding a secondary attachment for hooking up a spool gun to my Eastwood Mig 175. I had repaired the original wire drive connector with a 3D printed gas supply ring, which accepts the gun hose plug, so put it to use. I had ordered a replacement drive housing from Eastwood, and made a functional strain relief plug to hold the hose end.

The machine cabinet was lacking sufficient room to add the drive housing, so I attached it to the side support rail of the cart. Rather than employ a second gas solenoid for the Argon gas, I chose to use a diverter valve, downstream from the original solenoid in the machine, which tucked, neatly, inside. Now, it is a simple matter to change from one gun to the other by interchanging the small gun trigger plug, flipping the diverter valve, and switching from the machine drive to spool gun drive. I have my C25 and Argon gas bottles plumbed to my machines with a variety of T connections, so it is easy to change gases.
