Cause:
Remedy:
Output voltage is greater than 110V
Switch machine off and on again; if error keeps recurring,
have machine serviced
The mains voltage is outside the tolerance range
Check mains voltage, switch machine off and on again; if
error keeps occurring, have machine serviced
Current flowing via machine earth
Check ground (earth) connection to workpiece, switch
machine off and on again; if error keeps occurring, have
machine serviced
Short circuit between electrode holder and grounding
(earthing) terminal
Rectify short circuit, switch machine off and on again; if
error keeps occurring, have machine serviced
Internal error
Switch machine off and on again; if error keeps recurring,
have machine serviced
