SECTION 4- MAINTENANCE & BASIC TROUBLESHOOTING
MAINTENANCE
Please disconnect power to machine before performing maintenance.
Check periodically whether cable connection is in good condition (esp. plugs). Tighten any loose connections. If
there is oxidization, remove it with sandpaper and then reconnect.
Clean the dust inside the machine periodically with dry and clean compressed air. If welding environment has
heavy smoke and pollution, machine should be cleaned daily. The pressure of the compressed air should be at a
low pressure in order to avoid the small parts inside the machine being damaged.
Avoid water and vapor entering the machine. If this occurs, dry machine internals and check the insulation of
the equipment (including that between the connections and that between the connection and the enclosure).
Only when there is no moisture present, can the machine be used.
Check all cables periodically, to be sure they are in good condition with no worn spots or cracks in outer
insulation. If there is any dilapidation, rewrap it or replace all damaged cables.
Put the machine into clean packing and in a dry location if it is not to be used for an extended period of time.
If machine is in an environment that is in or near chemicals, cover machine when not in use.
Check gas hose periodically, to ensure it is in good condition and has no cracks, if any damage/wear is visible
replace hose.
