User Guide
As with all equipment, follow the maintenance and proper operating procedures outlined in the guides included with this
machine. By practicing a consistent maintenance and cleaning schedule, will ensure the reliability and productivity of the
machine. Follow all guidelines and safety precautions outlined in the user guide of the table, along with the equipment
attached to the machine.
• Regular cleaning ensures that the table runs as precisely as possible. A build up of dust can put stress on parts
and cause excessive wear or lead to cutting problems.
• It is recommended to wipe down any exposed, un-coated metal and spray with a dry silicone lubricant and
wipe off the excess. This process will help eliminate any corrosion build up on the exposed metal.
General Maintenance
Daily Maintenance:
Plasma Power Supply:
The plasma power supply and torch body will need to be evaluated between material thicknesses or prior to cutting.
Remove and check if the consumables need to be changed. Apply the following to know when the consumables need to be
changed:
For reference and complete maintenance on the FlexCut and FineLine plasma power supplies, see their Owners Manual.
The nozzle is the most frequently replaced consumable. A sign the nozzle needs to be
changed is an excessive amount of both dross and bevel angle appearing in your cuts. On the
nozzle itself, you’ll find that a larger orifice or an irregularly shaped hole will be the telltale
signs of excessive wear.
The shield cap: hold it up to a light and check if any of the holes are plugged. If they are then
replace the shield. These holes are the outlet for the shield gas, and when clogged, they can
misshape the plasma arc which leads to imprecise cuts.
The retaining cap is the most durable of the consumables, and will only need to be replaced
when corrosion, clogging, or cracking is physically apparent.
The swirl ring
will need to be checked intermittently for clogs or cracks.
The electrode:
pay close attention to the amount of Hafnium left in the tip. The larger the
crater within the electrode tip, the more wear that the electrode has gone through. Replace
the electrode if the center pit depth is greater than .06” (1.5 MM). Also, notice darker swirl
marks near the tip of the electrode. Although these swirl marks don’t have a correlation
with the life of the electrode, they do indicate contaminants within the air supply, such as
excessive moisture or oil.
