SPOOL GUN SET-UP AND WELDING  

(Spool Gun Available Separately, Not Included)

SET-UP FOR SPOOL GUN WELDING

The Eastwood MIG 140 is designed to accept an Eastwood #20172 Spool Gun (available separately, not included) which allows for easy feeding of aluminum  
wire to expand the MIG 140 welding capabilities. This is an optional accessory and can be purchased separately from Eastwood.
A cylinder of 100% Argon Gas (not included) from a local welding supplier is also required. 

•  Open the side door of the welder and cut the MIG Wire from the Spool.  

NOTE:

 DO NOT allow the Spool of wire to unravel.

•  Pull the remainder of the cut MIG wire from the MIG Gun Nozzle.
•  Remove the MIG Gun & Cable Assembly from the Cable/Gas Connection Socket.
•  Plug the Brass Body End of the Spool Gun Cable Assembly into the designated 

MIG Gun Cable/Gas Connection Socket 

(FIG 18)

, seating it fully and firmly. 

IMPORTANT NOTE:

 The Brass Body End of the Spool Gun Hose/Wire Cable 

MUST BE fully seated against the base of the drive assembly socket or gas may 
either leak or not be able to pass through the connections to the end of the Spool 
Gun 

(FIG 18)

.

•  Tighten the MIG Gun Tensioner Wing Screw finger tight. 
•  Connect the Male Metal Plug to the Female Cannon Plug connection on the front 

of the Welder 

(FIG 18)

.

INSTALLING THE GROUND CABLE AND CLAMP

•  The Ground Cable Clamp installation is the same as for the MIG Gun.

THREADING WELDING WIRE THROUGH THE SPOOL GUN (FIG 19).

•  Push button to open Spool Gun Side Cover.
•  Remove the Thumbscrew that retains the Wire Spool.  

IMPORTANT NOTE:

 Thumbscrew has Left-Hand threads.

•  Place Wire Spool on Spindle and replace the Thumbscrew.
•  Loosen the Wire Tensioning Screw until it is possible to feed the welding wire 

through the drive roller grooves.

•  Feed the wire by hand from the Spool into the Wire Inlet Guide, past the Drive 

Rollers and into the Wire Inlet Tube. 

•  Tighten the Wire Tensioner Thumb Screw until it applies light pressure onto the 

welding wire. 

NOTE:

 If this is too tight it will deform the wire and cause feeding 

issues, if it is too loose the drive roller will slip on the wire.

•  Remove the Nozzle and Contact Tip.
•  Close the Spool Gun Side Cover.
•  Plug in Welder to power source and turn on the Welder.
•  Trigger the Spool Gun to feed the wire and adjust the Wire Tensioner Thumb Screw so that the wire does not slip.
•  Replace Contact Tip and Nozzle.
•  Feed wire through the gun and cut the wire exposing a ~3/4” length beyond the contact tip.
