Electric shock can cause INJURY or DEATH.
IMPORTANT- Be sure that the power source and feeder are in the off position. Make sure input power to the power source is
disconnected at the electrical breaker box before attempting installation of this unit.

INSTALLATION
1.) Lay the PROFAX Mig-Gun out in a straight line.
2.) Push the brass connector end of the gun cable into the brass adapter on the outgoing side of feeder wire drive until it is fully seated.
Secure the cable with the set or hand screw in the adapter.
3.) Install the control plug assembly into mating socket on gun cable and into trigger circuit receptacle on feeder.
4.) Relieve tension and disengage drive rolls. Feed wire by hand through drive rolls, outgoing guide and adapter plug until wire is at least one
to two feet inside of PROFAX Mig-Gun.
5.) Reset drive rolls and apply proper tension. Keep gun in a straight position. Continue to feed wire through gun and contact tip by using
inch button on feeder or gun trigger.
6.) When you activate gun trigger, the contact tip and welding wire protruding from tip are electrically “HOT”. Set the power source to the
proper settings for wire size and welding application to be used. Make sure the shielding gas supply is adjusted to the proper flow rate.
Gun is now ready for operation.
GUIDELINES TO AVOID WIRE FEEDING PROBLEMS AND
TO KEEP YOUR MIG-GUN OPERATING SMOOTHLY
1.) Use only clean rust free good quality welding wire.
2.) Keep cable assembly as straight as possible, do not kink or pull cable over sharp corners or allow cart wheels or trucks to run over
cables.
3.) Make sure contact tip is tightly screwed into the gas diffuser at all times, also make sure that the gas diffuser is tightly screwed into the
conductor tube. Retighten the diffuser and tip periodically. Frequently clean contact tip and nozzles. The use of a good anti-spatter
compound will increase tip and nozzle life and make spatter removal easier. If contact tip becomes deformed or arced at the end, replace
immediately.
4.) Maintain and make certain all gun connections are secured and electrical connections are tight. New guns should have all electrical
connections retighten after several days of initial use. Check all gas hose connections on a regular basis to make sure no leakage or loss
of flow occurs.
By following these simple guidelines you will
extend the life of your new PROFAX Mig-Gun.
Keep all mechanical and electrical connections tight.
