8. With the electrode removed, inspect the cooling tube in the torch head for
damage.
If using the copper electrode, the torch head uses cooling tube P/N BK277007. If
replacement is required, use tool P/N BK200109.
If using the silver electrode, the torch head uses cooling tube holder assembly
P/N BK279216. Remove this using the tool (socket P/N BK277087 & driver P/N
BK277086) and inspect the o-rings for damage. Apply a small amount of o-ring
lubricant before re-installing in the torch head.
9. Wipe any excess o-ring lubricant off of the torch base and head.
Arc Starting Console (ASC)
1. Open the cover (door) of the arc starting console and verify that all leads and hoses
are tightened securely. Only tighten the fittings enough to make a water or gas
seal. The fittings are subject to damage if over tightened.
2. For systems that include ASC with RHF, check the spark gap electrodes for signs of
wear. Replace electrodes that have rounded faces. Use a clean feeler gauge and
set the spark gap to .015" (.38 mm).
Work Ground
1. Verify that the work ground lead is securely fastened to the star ground on the
cutting table, and that the connection point is free from corrosion. Use a wire brush
to clean the connection point if necessary.
