Electric Shock can cause INJURY or DEATH.
IMPORTANT: Before installing this equipment be sure that the input power to the welding power source has been disconnected at the electrical
breaker box, and that the power switch on the power source and wire feeder are in the off position.
See safety information sheet supplied with this manual.
® The PROFAX 600 amp water cooled Mig-gun comes standard with a PROFAX TWECO style rear connection that will mate to the PXTAK-1 or
PXTLAK-1 adapter block, or direct connect to any wire feeder that will accept this type of connection. See direct connect versions and
ordering information on the opposite side of this page. Contact your welding supply distributor for availability of any direct connect version not
listed.

INSTALLATION
1. Lay the gun out in a straight line and make sure that the gun is equipped with the proper contact tip and conduit for the type and size of
wire to be used. Also make sure that the adapter, wire feeder guides and drive rolls are correct for the type and size of wire to be used.
2. Push the brass connector end of the gun cable into the outgoing side of the adapter block or drive housing until it is fully seated. Secure
the connector.
3. Install the trigger control cord to the mig gun and to the mating trigger receptacle on the wire feeder.
4. Relieve tension and disengage drive rolls on feeder. Cut wire end straight and feed wire by hand through wire feeder guides and into the
PROFAX mig gun at least one to two feet.
5. Reset drive rolls and apply proper tension. Keeping the gun in a straight position, continue to feed wire through the gun by using the wire
feeder inch button or gun trigger. Contact tip may need to be removed for wire to feed through properly.
CAUTION SHOULD BE TAKEN NOT TO POINT GUN AT FACE OR BODY WHEN FEEDING WIRE.
6. Install the supplied quick connect fittings onto your coolant circulator. The female fitting should be connected to the water out side and the
male fitting to the water return side.
7. Attach the quick connect fittings on the PROFAX Mig-gun to the quick connect fittings on the coolant circulator. Fill the circulator with
clean coolant composed of an ethylene glycol and water mixture, such as PROFAX part no. PX7-2850. Turn the circulator on and verify
that the flow is at least ½ gallon per minute, with a maximum pressure of 75 psi.
IMPORTANT: Always turn the circulator on before you weld, and run the circulator for at least one minute after you stop welding. Use
only an ethylene glycol and water coolant; never use plain water as this can cause corrosion inside the gun. Check the
coolant level and cleanliness daily, and change the coolant every three months to avoid algae growth. Dirty coolant can
clog the quick connect fittings and coolant passages in the gun, reducing coolant flow. DAMAGE CAUSED BY
INSUFFICIENT COOLANT FLOW IS NOT COVERED BY WARRANTY.
CAUTION!: When you activate the gun trigger, the contact tip and wire protruding from the tip are electrically “HOT”.
8.
Set the power source to the proper settings for the wire size and welding application. Make sure the shielding gas and coolant are on and
adjusted to the proper flow rates.
GUIDELINES TO AVOID WIRE FEEDING AND COOLING PROBLEMS
1. Use only clean, rust free wires of good quality.
2. Keep cable assembly as straight as possible. Do not kink or pull cable around sharp corners or allow cart wheels or tr ucks to run over
cables.
3. Make sure contact tip is tightly screwed into gas diffuser. Frequently clean contact tip and nozzle. Use anti-spatter compounds to facilitate
spatter removal. If contact tip hole becomes deformed or shows arcing, replace immediately.
4. Verify often that all gun connections are secured and electrical connections are tight. Check all gas and water connections on a regular
basis to make sure no leakage or loss of flow occurs.
5. Always turn the coolant circulator on before using your PROFAX Mig-gun. Verify that the coolant is clean, and that the flow rate is at least
1/2 gallon per minute.
