DISASSEMBLY AND ASSEMBLY HINTS
Numbers in parentheses refer to Parts List page num-
ber and Item Number.
When applying torque on nozzle parts (P198-D,#1
through #8), hold gun by molded base (P198-D,#27)
or body block (P198-D#43), not by handle (P198-
D,#13) or motor(P198-D,#42).
When assembling handle to molded base, make sure
switch wires (P198-D,#19) are not pinched between
handle and motor. Pinched wires could cause welding
voltage to short to control circuit.
To remove gas power connector (P198-F,#72) from
gun body, remove handle so bottom plate can move
away from body.
To install woven insulating sheath (P198-D,#6), put
one end halfway into steel sleeve (P198-D,#5) and put
other end over barrel(P198-D,#8). Then push both
sleeves over barrel together.
When replacing brass barrel, first put antiseizing com-
pound on threads that go into aluminum body.
When reinstalling Telflon lin (P198-D,#9), put O-ring
(P198-D,#10) over narrow part of tubing.
Gas passage seal, set screw(P198-D,#24) [front], is
sealed with Teflon tape.
