Section 1 Introduction and Specifications
NOTICE:
This unit is DC output only and is not intended to be used for TIG welding Aluminum. This unit will weld with most welding electrodes (rods) in Stick mode, but it is not suitable for use
with E6010 electrodes. E6011 may be used, but performance may be brand dependent and not as good as with E7018 or any iron powder electrodes such as E7014 or E6013. The
plasma function on this unit is intended to be used in a support role for TIG and Stick welding and is not recommended to be used exclusively as a plasma cutter. Please be aware of
duty cycle limits while plasma cutting. Adjust plasma Amperage and consumable size according to the application used. This unit is not suitable for Plasma Gouging.
Use the I1MAX value to size the breaker. Use the I1EFF current to size wiring. Consult the NEC Article 630 for details concerning wiring and breaker requirements.

Air Compressor Requirement and Recommendations for Plasma Cutting. 4.5 - 5 CFM @ 90 PSI (127-142 lpm @ 6.2 bar)
Use a compressor with a minimum output of 5.3 CFM @ 90PSI (150lpm @ 6.2 bar), with 30 gallon (114
Liter) capacity or higher recommended for best operation. Pancake type and small oil-less compressors
are not suitable.
Duty Cycle/ Over Current Protection Yes, Self-diagnosing feature. (See code references at the end of this manual.)
Minimum Operating Plasma Cutting Air Pressure Approximately 40 PSI (2.7 bar) (safety cut-out threshold)
Low Pressure indicated by Error Code E06.
Maximum Supplied Air Pressure 90 psi (This is incoming pressure from the air compressor, not operating, or (From Compressor/Tank)
cutting pressure.) The air compressor MUST have a separate pressure regulator at the tank or inline to
control maximum supply pressure.
Recommended Maximum Daily Average Cut Thickness (Steel) 3/8” (12mm) Decrease 35-40% for Aluminum and Stainless (INOX).
Rated Maximum Quality Cut @ 10-12 IPM (@ 250-300mm / min) (Steel) 5/8” (18mm) Decrease 35-40% for Aluminum and Stainless (INOX).
Max Severance Cut @ 3 IPM (75mm / min) (Steel) 7/8” (22mm) Decrease 35-40% for Aluminum and Stainless Steel (INOX).
