5. Clean the torch receptacle if it does not need replacement:
a. Use a clean, lint-free cloth to wipe the internal and external surfaces.
b. Use compressed air to remove debris from the internal and external surfaces.

A cotton swab can be used for internal surfaces that are difficult to reach.
Do not leave cotton fibers inside the torch receptacle.
6. Before you supply power to the cutting system, make sure that the following components are
installed:

Consumables in the torch. (See How to install the consumables on page 136.)

Torch in the torch receptacle. (See How to install the torch into the torch receptacle on
page 138.)
Examine the torch lead
Before cutting system operation, examine the torch lead. Look for damage or wear.

Look for kinks, cracks, cuts, or excess wear. Replace the torch lead if you find these
conditions.

Make sure that all connections between the torch and torch lead are tight. Tighten loose
connections if found, but do not make the connections too tight. Do
not use tools to tighten
these connections.

If you have a power track that supports hoses, cables, and leads, examine their position on
the track. Look for evidence that the hoses, cables, and leads are exceeding bend radius
requirements during cutting system operation. (See
Bend radius requirements for hoses,
cables, and leads on page 56.)

Make adjustments if you find evidence of kinking, bending, or twisting.
