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.
5. Before you supply power to the cutting system, make sure that the following components are installed:
□
Consumables in the torch.
□
Torch in the torch receptacle.
Examine the torch lead
Inspect the torch lead for any damage, wear, or loose connections, and ensure it meets bend radius
requirements; replace or adjust as necessary.
Before you begin: Before cutting system operation, examine the torch lead. Look for damage or wear.
1. Look for kinks, cracks, cuts, or excess wear.
Replace the torch lead if you find these conditions.
2. 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 notuse tools to
tighten these connections.
3. 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. Refer to Bend-radius requirements for hoses, cables, and leads on page
66.
4. Make adjustments if you find evidence of kinking, bending, or twisting.
Indicators of emitter wear
Emitter wear can be described by the width, depth, and appearance of the electrode pit.
Emitter wear can indicate when to replace the electrode. The number of starts and the arc-on time can
have an effect on emitter wear.
Emitter wear can cause the cut quality to degrade. Your cut quality requirements will indicate when to
replace the electrode.
If an electrode needs replacement because of emitter wear, always
replace the nozzle at the same time as the electrode. Use the electrode
torque tool (429013) to correctly tighten the electrode.
