Check the connection for correct ground-
ing.
Lifting speed is too quick. Reduce the speed.
Initial cut but not completely
drilled through?
Potential connection problem. Check all connections.
Slag formation on interfaces?
Tool/material creates heat.
Allow the material to cool down and then
continue cutting
Cutting speed too low or current too
high.
Increase the speed and/or reduce the cur-
rent until the slag has been reduced to a
minimum.
Plasma burner component parts are
worn
Check and replace worn parts.
Arc stops during cutting?
Cutting speed too low.
Increase the cutting speed until the prob-
lem no longer exists.
Plasma burner is held too high and
too far away from the material.
Lower the plasma burner to the recom-
mended height.
Plasma burner component parts are
worn
Check and replace worn parts.
Workpiece no longer connected to
