GUN CABLES
CABLE CLEANING
Clean cable liner after using approximately 300
pounds (136 kg) of electrode. Remove the cable from
the wire feeder and lay it out straight on the floor.
Remove the contact tip from the gun. Using an air
hose and only partial pressure, gently blow out the
cable liner from the gas diffuser end.
Excessive pressure at the start may cause the dirt
to form a plug.
Flex the cable over its entire length and again blow
out the cable. Repeat this procedure until no further
dirt comes out.
CABLE REPAIR
The MAGNUM® 200FM gun features the use of
repairable cable connectors. If the cable ever gets
severely damage, it may be cut shorter and repaired
by the user. Repair cables as follows:
GUN TUBE END REPAIR (Requires 2 S19492-2
Terminals)
a. Remove the cable liner per Removal, Installation
and Trimming Instructions on page D-1.
b. Remove the gun tube per Gun Tubes and Nozzles
Section of pages D-1 and D2.
c. Remove three #6 screws from the gun handle, sep-
arate the two halves, and remove the cable from
the handle along with the trigger assembly.
d. Remove gun tube connector from cable by
unscrewing connector nut from gun tube connec-
tor. If the cable inner tube is difficult to remove from
the connector assembly, carefully slit it lengthwise
with a knife up to the brass connector.
e. Uncouple the strain relief by pushing its outer
housing toward the middle of the cable. Move the
strain relief and the cable boot toward the middle of
the cable, past the damaged section.
f. Cut off the damaged section of cable and strip off
the outer jacket as shown in Figure 2. Be careful
not to cut the insulation on the control wires while
stripping jacket. Strip the red and white control
leads 1/4 inch (6.4 mm) from the end and crimp a
new S19492-2 terminal to each lead.
NOTE: The cable contains three control leads. Any
two control leads can be used, provided the
two colors used are the same at both ends.
The extra lead is a spare that can be used
if one of the other leads breaks.
