Torch Lead Connections
Power Cable
IMPORTANT - PLEASE NOTE
——————————————————————————————
Water cooled torches use a #4 AWG power cable inside
a flexible hose. Because of the size of cable used,
these torches MUST be WATER COOLED.
——————————————————————————————
The torch fitting is screwed into the back of the torch block using a conductive
sealant. Air cooled torches, on the other hand, use a #2 AWG power cable,
which is secured to the torch in the same manner. The power cable fitting on
the other end connects to the power block inside the Cobramatic feeder.
Conduit
The Cobra Gooseneck comes standard with a Teflon-lined conduit. The torch
end is secured with a setscrew accessible through a hole in the handle.
The other end is connected to the wire feeder. 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, and then
secured with a plastic cable tie. The gas inlet tube is located in the middle of
the torch block, when viewed from the rear.
Water Hose
The water hose is pushed on to the inlet tube of the front body. The other end
goes to the return side of the water recirculator. The Water tube is located
in the upper right of the torch block, when viewed from the rear. Air cooled
torches do not have a Water Hose.
Electric Cable
A seven conductor control cable is used on the Gooseneck Torch. The torch
end of the control cable is secured to the back of the torch with a cable clamp
and the wires are joined to the motor, pot, and micro switch through two
connectors. The cabinet end has a 7 pin “W” clocked Amphenol connector.
See the schematic in the appendix for wiring information.
Section B Operation
General
The patented Cobra Gooseneck Torch maintains a constant, steady, uniform
wire 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 24VDC torch motor is controlled by a three (3)-turn
potentiometer in the torch handle.
