Maintenance of the torch will normally consist of a general cleaning of
the wire guide system, including tubes, drive rolls, and conduits at regular
intervals.
Remove spatter build-up from inside of nozzles with a hardwood stick.
The only parts on the RoboKing system that are subject to normal wear are
the conduit, contact tips, gas cups, front body liners, wire guides, drive and
idler rolls. A supply of these parts should be maintained on hand.
If repairs do become necessary, any part can easily be replaced by a
qualified shop maintenance personnel.
Your RoboKing System is designed to provide years of reliable service.
Normal wear and component failure may require occasional service.
The number of units in operation and the importance of minimal “down time”
will determine to what extent spare parts should be stocked on hand. See
the "Recommended spare parts list" for the most commonly replaced parts.

Regardless of which torch or feeder used, all MK Products’ push-pull guns
operate on the same principle. The 115 (42) VAC slave motor in the feeder
runs at a fast, constant speed, but has very low torque. It is always trying
to feed more wire than the torch motor wants, and when the motor gets all
it wants, it slows the slave motor, preventing a bird’s nest. Because of the
low torque produced by the slave motor, a brake system is used to prevent
wire overrun rather than tension. The drag adjustment in the spindle is
used simply to keep the wire slightly taut, so it will not pull off the spool while
feeding wire.
The high torque 24 VDC torch motor is controlled by a solid state speed
control. The torch motor is connected to the cabinet/control box via a control
