Torch Maintenance/Troubleshooting
Torch Front End Disassembly
Wear on torch parts is a normal occurrence to plasma cutting. Starting a plasma arc is an erosive process to both
the electrode and nozzle. Regularly scheduled inspection and replacement of PT-36 parts must take place to
maintain cut quality and consistent part size.
DANGER
1. Remove the Shield Cup Retainer.
If the shield cup retainer is difficult to remove, try to screw the nozzle retaining cup tighter to
2. Inspect mating metal surface of shield cup and shield cup retainer for nicks or dirt that might prevent these
two parts from forming a metal to metal seal. Look for pitting or signs of arcing inside the shield cup. Look
for melting of the shield tip. Replace if damaged.
3. Inspect diffuser for debris and clean as necessary. Wear on the top notches does occur, effecting gas volume.
Replace this part every other shield replacement. Heat from cutting many small parts in a concentrated area
or when cutting material greater than 0.75" (19.1mm) may require more frequent replacement.
