7.2 Welding Work
1. Align the wire tip with the welding position.
2. Set the multi-function selector switch to any of the SPEED (1) to (3) positions.
3. The arc will be generated only while the arc selection switch is set to ON with the clutch at
START and the direction selection switch is flipped to forward or reverse. If an arc stabilization
time is set, the arc will be generated with the carriage stopped for the set time. After the set
time has elapsed, the carriage will start moving.
4. When welding starts, observe the conditions carefully and adjust to the optimum cutting speed.
5. After the welding is finished, turn the direction selection switch back to neutral. Arc generation
and the carriage will stop.
