10.0 CLEANING & MAINTENANCE
All of the connectors at the end of the cable must be kept clean and free of
grease, oil, dirt or other contaminants. Keep the cap on the electrical multi-
pin connector when not in use.
From time to time (depending on the cleanliness of the tube/pipe being
welded, the type and quality of the arc gas and the number of welds done)
the rotor and weld head housing will build up soot, which should be cleaned
on a regular basis.
10.1 Use isopropyl alcohol and Scotch Brite or steel wool to
clean the both brass (male and female) power and
ground connectors. Rinse off all debris and dry before using.
10.2 After cleaning the brass power and ground connectors, use a very
small amount of o-ring lube, oil or grease on the female (brass)
connector o-ring to facilitate easier connecting and disconnecting
10.3 Use a clean lint-free cloth and isopropyl alcohol to clean the rotor,
(black) rotor guide ring, weld head housing and view window.
