Setting the Wire Drive Tension

WARNING: Arc flash can injure eyes! To reduce the risk of arc flash, make certain that the
wire coming out of the end of the gun does not come in contact with the work piece, ground
clamp or any grounded material during the drive tension setting process or arcing will occur.
1. Open the wire drive cover on the spool gun
2. Pull the trigger on the gun.
3. Turn the drive tension adjustment knob clockwise, increasing the drive tension until the wire
seems to feed smoothly without slipping.
4. Close the wire drive cover on the spool gun.
5. When set correctly, there should be no slippage between the wire and the drive roller under
normal conditions.

Adjusting the Spool Position

Before you begin welding, you may want to adjust the position of the spool so it is most comfortable for
you. There are three positions to choose from. To change the position of the spool:
1. With a flat tipped screwdriver, loosen the screw which connects the spool casing to the gun.
2. Pull the casing far enough away from the gun to allow the casing to rotate.
3. Rotate the casing to one of the three available positions, making sure that the grooves on the
gun are aligned with the grooves on the casing.
4. Push the casing and the gun back together.
5. With a flat tipped screwdriver, tighten the screw which connects the spool casing to the gun.

Operation

Description

Your new single phase inverter multi-function welder offers three welding functions in the same
power source. These functions can be selected with knob (6) on the front panel of the unit.
Fluxcore Wire Welding, "FCAW" and MIG Welding, "GMAW"
This welder offers the choice to weld in manual or synergic mode.
1. Manual Mode: The operator is required to set both the wire speed (Left Knob) and the
welding voltage (Right Knob).
2. Synergic Mode: As in manual function, the operator is required to set both the wire speed
(Left Knob) and the welding voltage (Right Knob). Once both parameters are set, the
synergic function allows the operator to move to different thickness of material to be welded
by simply adjusting the Left Knob. The correct voltage will be automatically set by the
machine's software.
Stick Welding, "SMAW"
Both rutile and basic electrodes can be welded. Welding current is adjusted using the Left Knob.
TIG Welding, "GTAW"
In the TIG position, a TIG torch with a trigger control and a gas valve in the handle is required.
The gas valve must be opened manually before welding and closed manually when welding is
completed. The arc is activated using the torch trigger. Using the Left Knob welding current can
adjusted.
