adheres to it.

J. Arc shuts off during operation; arc will not restart when torch switch is activated.

1. Power Supply is overheated (OC/OT lamp on), let unit cool down for at least 5 minutes.

Make sure the unit has not been operated beyond Duty Cycle limit. Refer to Section 2 for

duty cycle specifications.

2. Gas pressure too low (the TIP/GUN/GAS lamp on when press on torch switch is on),

check source for at least 4bar/60psi; adjust as needed. It is need to open the machine cover.

L. Torch cuts but cuts are of low quality

1. Amperage control set too low, increase current setting.

2. Torch is being moved too fast across workpiece, reduce cutting speed.

3. Excessive oil or moisture in torch, hold torch 1/8 inch (3 mm) from clean surface while

purging and observe oil or moisture buildup (do not activate torch). If there are contaminants
