Torch Gas Connections

Perform the following steps to connect the torch gas hoses to the manual gas
console, torch base, and manifold assemblies. See Figure 8.
Note: When making hose connections, only tighten the brass fittings
enough to make gas seals. The fittings are subject to damage if over
tightened.
7.5 Foot Shield Gas Hose
1. Route one end of the 7.5 foot (2.3 m) shield gas hose through the torch
handle and connect to the shield gas fitting on the torch base.
2. Connect the other end of the 7.5 foot (2.3 m) shield gas hose to the shield
gas outlet on the 5-gang manifold.
17 Inch Plasma Gas Hose
1. Route one end of the 17 inch (432 mm) plasma gas hose through the torch
handle and connect to the plasma gas fitting on the torch base.
2. Thread the torch handle onto the torch base, being careful not to twist the
torch leads and gas hoses when tightening the torch handle.
3. Tighten the base to the handle using a pin style adjustable spanner wrench
(fits 2" diameter with ¼" diameter pin).
4. Attach the 2-gang manifold assembly to the torch handle. The top of the
manifold bracket should be flush with the top of the torch handle.
5. Connect the other end of the 17 inch (432 mm) plasma gas hose to the
plasma gas outlet on the 2-gang manifold.
6. Mount the torch handle/base/manifold to the positioner. Note the alignment
indicators on the torch base (slot) and torch head (circle).
aligning the quick-disconnect torch base and head and should be oriented so
they are clearly visible when the operator is changing heads.

preflow/postflow outlet on the 5-gang manifold.
2. Connect the other end of the 6 foot (1.8 m) preflow/postflow gas hose to the
