Plasma Cutter
Operating Instructions and Parts Manual
Plasma Cutter
Plasma 275
- The plasma cutter’s working air
pressure range is 40-90psi. Notice:
the internal pressure switch will shut
off when the air pressure falls below
50psi. The switch only works when
the pressure rises to 50psi or above.
- Every 4-8 hours, check the air filter
on your air supply and remove
excess moisture. Too much moisture
in the cutter or torch may lead to
operational trouble.
- Always unplug the power supply
before checking for and removing
moisture.
3. Safety Requirements
- Never allow the torch to be aimed at
any part of a body.
- Make sure to wear protective
glasses and gloves while operating.
- Work only in well-ventilated areas. If
necessary, use exhaust/ventilation
fans to keep fumes or emissions
away from the breathing zone.
- Do not touch the work piece while
cutting.
- Do not cut a pipes, containers, or
other materials that contain, or have
ever contained, flammable or
explosive materials.
- Do not work underwater or in
wet/moist environments.
- Do not bend the torch cable sharply;
this may damage the air hose.

- Always turn off the power supply
prior to repairing or installing any
spare parts (e.g., torch, electrode,
nozzle, ground clamp, etc.).
- Never allow a person with a cardiac
pacemaker close to the working area
without the permission of a doctor.
The magnetic field produced by
plasma cutters during operation can
disrupt pacemakers and similar
devices.

pinched or damaged. If damaged,
replace immediately.
