 WELDING GUN INSTALLATION

(See Figure C-1, C-2 and C-3)

There is one spool of .025” (0.6mm) solid welding wire included with the welder. The welding

gun comes with a .025” (0.6mm) contact tip installed. If .030-.035” (0.8-0.9mm) wire is to be used,

change the contact tip to the appropriate size.

CONNECT THE WELDING GUN TO THE WELDING MACHINE

1. Power off the welding machine (switch is positioned at “O”).

2. Plug the welding gun into the access hole ○1 and plug it into to the connector block. Also,

thread the control wire of the welding gun through the access hole○1 and inset the control wire

into the gun trigger connector terminals. ○5

3. Tighten the wing screw ○3 attached to the connector block of the wire feed gearbox.

4. Make sure the Gun changing switch ○7 is in the correct position MIG for standard welding

and Spool Gun if optional gun is installed.

 WIRE DRIVE ROLL INSTALLATION

The reversible dual groove wire drive roll

attached to MIG140 has two wire grooves;

One for .025” (0.6mm) solid welding

wire and the other for .030-.035” (0.8-0.9mm)

solid or flux-cored welding wire. The

factory default installation is .025” (0.6mm).

In the event that .030” (0.8mm) - .035”

(0.9mm) welding wires are used, the wire feed

roll groove must be changed.

1. Ensure that the MIG140 welding machine is

powered off.

2. Unlatch the spring loaded pressure arm and Figure C-4

open the idle roll arm. ○1 and lift up the idle roll arm. ○2

3. Loosen the plastic screw ○3 that attaches the wire drive roll.

4. Remove the wire drive roll○4 and flip the wire drive roll over so that the .030” (0.8mm) mark

faces the user.

5. Reinstall by putting back the wire drive roll and tighten the plastic screw.
