the rear Handle nut. Spiral steel conduits are available when using hard
and cored wires.
Gas Hose
The gas hose is pushed on to the inlet tube of the front body. The gas inlet
tube is located in the top center of the torch when viewed from the rear.
Water Hose
The water hose is pushed on to the inlet tube of the front body. The Water
tube is located in the lower left of the torch when viewed from the rear.
Electric Cable
A seven conductor control cable is used on RoboKing Torch, although only
2 conductors are used. The torch end of the control cable is secured to the
back of the torch with a cable clamp and the wires are connected to the motor
through a connector. The cabinet end has a 7 pin “W” clocked Amphenol
connector. See schematic for wiring information.

eScription
The RoboKing is designed to be used in automation processes and is unique
in its design from other torches made by MK Products. The RoboKing Torch
maintains a constant, steady, uniform feed speed, regardless of curved or
looped wire conduit. The constant push exerted by the slave motor in the
cabinet, combined with the pull of the torch motor, causes the wire to literally
float friction-free through the wire conduit. The 24 volt DC torch motor is
controlled by the speed control in the Cobramatic II cabinet.
There is no trigger in the torch to start the arc, this is controlled by means
of an outboard control.

A 19.5:1 24VDC motor gear box is used on this version of the RoboKing
Torch. The motor gear box attaches to the angle head with three (3) Allen
screws. The torch serial number is stamped on the angle head. There are no
spare parts for the motor gear box; it must be replaced as a whole unit.

General
The RoboKing comes setup from the factory with the drive roll & idler
roll requested at the time of order. Other sizes of grooved drive rolls for
aluminum wire are also available (see Optional Kits). Use Knurled drive
rolls for all steel applications. One set will feed all wire diameters from .030
(0.8mm) to 1/6"(1.6mm)
Drive roll tension is accomplished by means of a pressure-adjusting screw
located on the left hand side of the torch. Proper tension is achieved when
wire does not slip when a small amount of pressure is added to the wire
as it exits the tip.
