Cut off the excess wire that extends past the end of the nozzle.
Ÿ
Fine-tune the wire drive pressure with the pressure arm adjustment knob (G).
Ÿ
Turn the pressure adjustment knob clockwise to increase the driving pressure until the wire seems to feed smoothly without
Ÿ
slipping.
Note: If TOO MUCH pressure is applied, you can crush the wire and create wire feeding problems. If TOO LITTLE pres-
sure is used, the wire will slip on the drive rolls, and no wire will be fed.
When the driving pressure is set correctly, there should be no slippage between the wire and the drive roller. But if an obstruction
Ÿ
occurs along the wire feed path, the wire should slip on the drive roller. You can check it by squeezing the wire between two
fingers with moderate force as it comes out of the gun. If this stops the wire from feeding, increase the pressure until the wire
feeds through your fingers without issue.
Double-check your spool tension: When wire feeding stops, the wire comes off the spool with some curvatures while it should not
Ÿ
relax so much that the wire loosens on the spool. off the curvature the coiled wire naturally reverts to. It should also not relax so
much that the wire begins to loosen on the spool.
CORRECT
KEEP THE GUN STRAIGHT. WHEN FEEDING A NEW WIRE THROUGH THE LINER, MAKE SURE THE WIRE IS CUT
CLEANLY (NO BURRS OR ANGLES) AND THAT AT LEAST 1" FROM THE END IS STRAIGHT (NO CURVES).
FAILURE TO FOLLOW THESE INSTRUCTIONS COULD CAUSE DAMAGE TO THE LINER.
WHEN CHECKING THE CORRECT EXIT OF THE WIRE FROM THE GUN DO NOT BRING YOUR FACE NEAR THE
GUN. YOU MAY RUN THE RISK OF BEING WOUNDED BY THE OUTGOING WIRE. DO NOT BRING YOUR FINGERS
CLOSE TO THE FEEDING MECHANISM WHEN WORKING! THE ROLLS, WHEN MOVING, MAY CRUSH FINGERS.
PERIODICALLY CHECK THE ROLLS. REPLACE THEM WHEN THEY ARE WORN AND COMPROMISE THE
REGULAR FEEDING OF THE WIRE.

OPERATION

Performance Data Plate And Duty Cycle

On the machine, there is a plate that includes all the operating specifications for your new unit. The duty cycle rating of a welding
machine defines how long the operator can weld and how long the welding machine must rest and be cooled. Duty cycle is
expressed as a percentage of 10 minutes and represents the maximum welding time allowed. The balance of the 10-minute cycle is
required for cooling.
For example, a welding machine has a duty cycle rating of 30% at the rated output of 90A. With that welding machine, you can weld
at 90 A output for three (3) minutes out of every 10 min with the remaining seven (7) minutes required for cooling.
The duty cycle of your new welding machine can be found on the data plate affixed to the machine. The picture below shows that
the "X" row lists duty cycle percentages while the "I2" row lists the amp draw corresponding to the duty cycle. Various duty cycles at
other amperages are listed on your data plate.
