7. Ensure that the top of the adjustable water-cooling tube in the holders is the proper height when
changing to a different tip length.
8. Coat the tip with a thin film of cup grease before placing it in the holder to simplify removal.
9. Use ejector type holders for easy tip removal that won't damage the tip walls.
10. Clean the tip taper and holder taper on a regular basis, removing any foreign materials.
11. Perform dressing of electrodes on a regular basis to maintain the correct contour.
12. Use a rubber mallet to align holder and tips, rather than a metallic tool.
Avoid these potential sources of weld problems:
1. Never weld using unidentified electrodes or electrode materials.
2. Avoid using special-purpose or offset tips if the job can be handled with a standard straight tip.
3. Do not use a small tip for welding heavy gauge materials or a large tip on small piece.
4. Do not overlook turning on the cooling water to the appropriate force when beginning to weld.
5. Never use a water hose that does not firmly fit the water connection nipples.
6. Avoid leaky, clogged or broken water connections.
7. Do not use holders that have leaking or deformed tapers.
8. Do not use electrode holders without an adjustable internal water cooling tube.
9. Avoid leaving the electrodes unused in tapered holder seats for long periods.
10. Do not use pipe wrenches or similar tools when removing electrodes.
11. Never dress an electrode using a coarse file.
