USER RESPONSIBILITY

Variation such as plate chemistry, plate surface condi- tion (oil, scale), plate thickness, preheat, quench, gas type, gas flow rate and equipment may produce results different than those expected. Some adjust- ments to procedures may be necessary to compen- sate for unique individual conditions. Test all proce- dures duplicating actual field conditions.

DESIGN FEATURES AND

ADVANTAGES

•Light weight

•Continuous output control

•Indicator LEDs

•Cooling fan

•Rapid arc restrike for cutting across gaps

•3 second arc delay for safety

•Adjustable air pressure regulator with locking feature

•Part-in-place verification for safety and proper operation

•Thermostatic protection with thermal indication

•Air inlet filter with water purge button to protect air path and torch

•Lighted ON/OFF switch

•High input voltage protection

CUTTING CAPABILITY

The PLASMA 20 is rated for 20A @ 40% duty cycle. The unit is designed to cut up to 3/8” inch mild steel, but has the capability to cut other metals such as stainless and aluminum (travel speed will vary).

TORCH CONSUMABLES

The torch consumables consist of an Electrode, Gas Distributor Ring, Nozzle, and Shield Cup. The con- sumable parts must be placed in the correct order and secured properly for the unit to operate.

LIMITATIONS

•For indoor use only.

•Do not exceed output current and duty cycle rating of machine. Do not use the PLASMA 20 for pipe thawing.

•Do not power with generators or engine drives.

1.ON/OFF Switch – In the ON position the machine is ready for normal operation. All system control circuits are activated. OFF position deactivates control circuits.

2.Output Current Knob-Adjusts the cutting current supplied by the machine according to the thick- ness of material/speed.

3.Green LED – Turns ON when input voltage is applied within normal range – blinks slowly when input voltage goes above 130Vac, or below 95Vac.

4.Red LED – Turns ON when torch is triggered Blinks quickly during 3 second safety pre-flow prior to pilot arc ignition Blinks slowly if cutting arc is not initiated after 3 second pilot arc ignition.

5.Yellow LED – Turns ON when the thermal protec- tion is activated. Blinks slowly when the under pressure protection is working (the pressure is under 55 PSI, 3.8 Bar)

6.Air Regulator – Adjusts the input air pressure – pull upward to unlock, press down to lock – nomi- nal air pressure setting is 65 PSI, 4.5 Bar.

Note: Regulator should never be set above 87 PSI (6 Bar).
