Electric shock can cause INJURY or DEATH.

IMPORTANT- Disconnect all electrical power to the welding power source and wire feeder before attempting installation of this unit.

Your PROFAX 500 Amp AMT Mig-Gun comes standard with a Tweco style rear connector. Adapter Kits for most domestic style feeders as well as a Euro-Quick connector for European style feeders are also available. Please note that non GMA wire feeders will require a gas solenoid valve.

INSTALLATION

1.) Make sure that the gun is equipped with the proper contact tip and conduit for the type and size of wire to be used before installation.

2.) Make sure that the adapter, the feeder outgoing guide, and the drive rolls are correct for the type and size of wire to be used.

3.) Lay the PROFAX AMT Mig Gun out in a straight line.

4.) 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.

5.) Remove the nozzle and contact tip from the AMT Mig Gun.

6.) Relieve tension and disengage drive rolls. Feed wire by hand through drive rolls, outgoing guide and adapter plug until wire is at least one too two feet inside of PROFAX AMT Mig Gun.

7.) Reset drive rolls and apply proper tension. Keep gun in a straight position. Continue to feed wire through the gun by using the inch button on the feeder or gun trigger.

8.) Install the nozzle and contact tip back onto the AMT Mig Gun.

9.) 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 good quality welding wires that are clean and rust free.

2.) Keep the cable assembly as straight as possible, and do not kink or pull cable around sharp corners or allow carts or

trucks to run over the cable assembly.

3.) Make sure the contact tip is tightly screwed into the gas diffuser at all times. Frequently clean the contact tip and nozzle.

The use of a good anti-spatter compound will increase tip and nozzle life and will make spatter removal easier. If the contact tip becomes deformed, arced or worn at the end, replace it immediately.

4.)On a regular basis, check all gun, cable and gas hose connections. Make sure they are clean and tight.

BY FOLLOWING THESE SIMPLE GUIDELINES YOU WILL

EXTEND THE LIFE OF YOUR PROFAX AMT MIG GUN.
