Wire Feed Overload Protection - Lincoln Electric POWER WAVE SVM135-B Service Manual

B-10
WIRE FEED OVERLOAD
PROTECTION
The wire drive has solid-state overload protection of
the wire drive motor. If the wire drive motor becomes
overloaded for an extended period of time the wire
drive will issue a shutdown command to the Control
Box and force its STATUS light to blink between
green and red. The Control Box turns off the power
source, wire feed and gas solenoid. The status light
on the wire drive will continue to blink between green
OPERATION
and red for about 30 seconds before the wire drive
will automatically reset. At that time, the wire drive
will issue a shutdown over command to the Control
Box that will return the system to normal operation.
The wire drive will force its STATUS light to solid
green.
Overloads can result from improper tip size, liner,
drive rolls, or guide tubes, obstructions or bends in
the gun cable, feeding wire that is larger than the
rated capacity of the feeder or any other factors that
would impede normal wire feeding.
