Instruction Notes

1. The cutting machine can perform in an environment where conditions are particularly harsh:
it can withstand outside temperatures between 14 and 104 degrees Fahrenheit and a humidity level
of up to 80%.
2. Please try to keep machine dry.
1. Working area MUST be adequately ventilated.
2. No over-load! Your machine can be damaged by over-loading.
3. No over-voltage! Internal circuitry can be damaged by over-voltage.
4. An internal heat-variable component is initialized if machine exceeds duty cycles. The cutting machine
will stop working immediately, and an internal red diode will be lighted. Note: The user does not need
to break the circuit; the fan will continue working in order to cool the machine. Once temperature is
reduced to allowable range, machine can be operated again.
1. Ensure that the copper tip is not in direct contact with the work piece while cutting. To protect copper
tip, torch should be inclined and maintain a distance of 1 mm from inter-hole of copper tip to the work
piece.
2. If pilot arcing functions improperly, try to remove oxidization of the electrode on the torch with sand
paper.
1. Dust created by compressed air should be removed regularly. If work environment is polluted with
smoke and dust, daily maintenance is required.
2. Ensure adequate air pressure exists to protect internal components.
3. Check all connectors to ensure firm connections.
4. Protect machine from water or dampness.
5. When machine is not in use for a long period of time, it should be properly packed and stored in a dry
environment.
6. Replace any worn consumables to avoid damage.
