Maintenance
4. Unscrew nozzle retainer and pull nozzle straight out of torch body. Inspect insulator portion of the nozzle
retainer for cracks or chipping. Replace if damaged.
Inspect nozzle for:
• melting or excessive current transfer.
• gouges from internal arcing.
• nicks or deep scratches on the O-ring
seating surfaces.
• O-ring cuts, nicks, or wear.
• Remove tungsten particles (from the
nozzle) with steel wool.

NOTE:
Discoloration of internal surfaces and small black starting marks are normal and do not effect cutting
performance.
If the holder was tightened sufficiently, the electrode may unscrew without being attached to the electrode
holder. When installing the electrode, use only sufficient force to adequately secure the electrode.
5. Remove electrode using electrode removal tool.
6. Disassemble electrode from electrode holder. Insert flats on the holder into a 5/16" wrench. Using the electrode
tool, rotate electrode counter-clockwise to remove. Replace electrode if center is pitted more than
0.06" (1/16") or if the flat has become irregular in shape or is worn to a larger diameter.

Note:
The electrode has two usable ends. When
one end is worn, flip electrode to other end
for continued use.
