Plasma Torch Parts Wear & Replacement - Weldclass CutForce CF-40p Operating Instructions Manual

10.4 Plasma Torch Parts Wear & Replacement
It is very important to recognise that plasma torch consumables wear as part of normal operation and
should be replaced in a timely manner.
Operating a torch with worn consumables will cause poor cutting results and possible damage to the torch
and machine itself. Damage caused by untimely replacement of consumables will not be covered by
warranty.
Use the following guidelines to determine when consumables should be replaced:
Cutting Tips: The cutting tip has a small calibrated orifice that the plasma passes through. If the orifice
becomes partially blocked, deformed or enlarged, the cutting tip should be replaced.
Electrodes: The electrode has a small silver 'hafnium' insert in the end of the tip. This is what generates the
plasma ions. Once the hafnium insert is gone or is damaged the tip must be replaced.
Swirl Ring: This should be replaced if broken, chipped, cracked, worn or badly heat damaged. The small air
holes do wear over time. Whilst it is not usually visible with naked eye it can cause the flow & swirl of the
air to be disrupted with causes an unstable or deformed arc.
Retaining Cap: This should be replaced if broken, chipped, cracked or badly heat damaged.
Tips and electrodes: These should wear reasonably evenly and it is normal practice to replace them both
together. If a new tip is inserted with a worn electrode the tip will wear much more quickly than if the
electrode was also replaced at that same time. If tips or electrodes are wearing much faster than the other
component it is likely to be caused by one of the following:

Wet or dirty air supply

Incorrect air supply

Poor operator technique

Damaged torch head
It is also very important to only use genuine Weldclass consumables and parts for the plasma torch. They
are engineered to suit the machine and non-genuine items may cause lack of performance, short life span,
torch and machine damage and void warranty.
