Maintenance

Exposure to extremely dusty, damp, or corrosive air is damaging to the welding/cutting machine. In order to prevent any possible failure or fault of this welding/ cutting equipment, clean the dust at regular intervals with clean and dry compressed air of required pressure.

Kerf: The tip orifices focus the plasma stream to the work piece. It is important to use the correct size tip for the amperage being used, for example a tip with a 3/64" orifice is good for 0-40 amps whereas a 1/16" orifice is better for 40-80 amps

Air Pressure and Volume: The RazorCut45 air pressure is pre-set at 4.5 psi and requires a flow rate of 6.0 CF/M.
