• Faulty components in unit return for repair.
8. Torch cuts but low quality
• Current (A) control set too low, increase the current setting.
• The torch is being moved too fast across the workpiece, reduce cutting speed.
• Excessive oil or moisture in torch, hold torch 1/8 inch (3 mm) from a clean surface while purging and
• Observe oil or moisture build-up (do not activate torch). If there are contaminants in the air, additional
filtering may be needed. Refer to sub-micronic air filter page page 17.
