2 – Torch Setup
9. Use 2 wrenches to loosen the gas fitting that secures the torch body to the torch lead.

Heating the gas fitting can help loosen the threadlocker and make removing the torch
body easier. Slowly heat only the fitting with a heat gun until you can easily loosen the
fitting.
10. Cover the end of the gas line on the torch lead with tape to keep dirt and other contaminants from getting in the gas
line.
11. Route the torch lead through the robot’s through-arm cavity.
12. Being careful not to get any threadlocker on the conical surface of the gas tube fitting, apply a drop of threadlocker,
included in the kit, to the threads of the gas tube fitting on the torch body.
 The drop should not be wider than 2 threads in diameter.
CAUTION!
Do not apply heat to the wires. Heating the wires could cause damage to the connections in the torch
lead.
CAUTION!
Always use 2 wrenches to properly loosen and tighten the hex nuts and bolts mentioned in these
procedures. A strong threadlocker is used to assemble the torch, and loosening the nuts incorrectly
can damage the threads.
CAUTION!
Do not get any threadlocker on the conical surface of the gas tube fitting to avoid causing damage
to the torch. If any threadlocker does get on this surface, clean it off immediately.
