TORCH
Periodically, according to its use or to cutting faults verify wear of the parts connected to plasma arc:
Shield Cup:
Unscrew manually from head of the torch. Clean throughly and replace if damaged (burns, distortions or cracks).
Verify integrity of superior metal sector (actuator torch safety).
Tip:
Check wear of plasma arc hole and of inner and outer surfaces. If the hole is widened compared to its original
width or if it is damaged, replace tip. If surfaces are particularly oxidized clean them with extra fine abrasive paper.
Air Distribution Ring:
Verify the are no burns or cracks or that airflow holes are not obstructed. If damaged, replace immediately.
Electrode:
Replace electrode when crater settling on emitting surface is about 2mm.
WARNING!
• Before making any operation to the torch let it cool at least all along the “postgas” period.
• Except for particular cases it is advisable to replace electrode and tip AT THE SAME TIME.
• Respect assembly order of torch parts (reserved compared to disassembly).
• Be sure that the Air Diffuser ring is positioned correctly.
• Reassemble shield cup tightening securely by hand.
• Never assemble shield cup without having assembled electrode distributing ring and tip beforehand.
• Timely and appropriate control procedures on torch parts are essential for safety and functionality of the cutting
system.
TORCH BODY, HANDLE AND CABLE
• These parts usually need no particular maintenance with the exception of a periodic inspection and an
accurate cleaning to be made WITHOUT THE USE OF SOLVENTS.
• In case of damages to the insulation such as breaks, cracks and burns or even a loosening of electric
conductors, the torch CANNOT BE USED FURTHER SINCE SAFETY CONDITIONS HAVE NOT BEEN
RESPECTED.
• IN THIS CASE, REPAIRING (EXTRAORDINARY MAINTENANCE) CANNOT BE MADE ON SITE BUT NEEDS
TO BE DELEGATED TO A SERVICE CENTER TO MAKE SPECIAL REST TRIALS AFTER REPAIRING HAS
BEEN EXECUTED.
• In order to keep the torch and the cable efficient it is necessary to follow these precautions:
• DO NOT touch torch and cable with warm or hot parts.
• DO NOT strain the cable.
• DO NOT move the cable on sharp edges or abrasive surfaces.
• Gather the cable in regular coils if it is too long.
• DO NOT step on the cable.
