5.2 Torch Front End Disassembly
1. Remove shield retainer.
NOTE:
If the shield retainer is dicult to remove, try to screw the nozzle retainer tighter to relieve pressure on
the shield.
2. Inspect mating metal surface of shield and 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. Look for melting of the
shield tip. Replace if damaged.
3. Inspect diuser for debris and clean as necessary. Wear on the top notches does occur, eecting 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.
