Disassembly of torch - removing consumables
1.
To disassemble the front end, hold the torch with the shield in an upright position as shown in Figure
-. This will prevent the nozzle, electrode, and swirl baffle from falling free when the shield is re-
moved.
.
If the torch is fixed and cannot be rotated upward, the alternate method of disassembly is to disas-
semble the electrode, swirl baffle and nozzle as above being careful not to damage them by letting
them fall.
3.3
installing consumables - assembly of torch
Apply a small amount of lubricant - 1767, supplied in spare parts kit, to the heat shield or to the o-ring
as shown in Figure -1. Check o-ring for damage whenever the shield is removed. Replace if necessary.
1.
To assemble with the torch front end facing up, assemble electrode, swirl baffle, tip and heat shield in
that order as shown in Figure -. The swirl baffle is symmetrical and it can be positioned either way.
Tighten heat shield snugly to hold the parts in firm contact with each other and the torch head. Do
not overtighten the heat shield.
.
If the torch is fixed and cannot be rotated upward, the alternate method of assembly is to assemble the
electrode, swirl baffle and nozzle as above and drop them into the heat shield. Then thread the heat
shield upward into the torch body.
Lubricant can be applied to O-ring or Heat Shield
