X8 SuperSnake GT02XW Manual 1920890, rev. 1944

 

Feed roll pressure adjustment

Adjust the feed roll pressure with the adjustment roller mounted on the pressure arm. The load applied should be sufficient to overcome a light braking force applied by hand to the filler wire as it exits the welding gun contact tip.

For smaller diameter and soft filler wires, less feed pressure is required. Refer to the table in the end of this chapter for further guidance.

 

1.

Release the pressure arm by lifting it up.

2.

Turn the roller adjuster on the pressure arm to adjust the roll pressure. A graduated scale next to the adjustment roller indicates the pressure load in newtons (N). For the correct amount of pressure, refer to the table in the end of this section.

3.

Lock the adjustment by closing the pressure arm.

 

Excessive pressure flattens the filler wire and may damage coated or cored filler wires. Excessive pressure also unnecessarily wears the feed rolls and increases gearbox load.

The use of knurled feed rolls in the X8 MIG Welder’s wire feeder unit with the X8 SuperSnake GT02XW subfeeder is not recommended.

When the X8 SuperSnake GT02XW subfeeder is selected in the X8 wire feeder settings, wire inch feature will feed the wire automatically to the system when the Wire inch button on the wire feeder panel is pressed.
