Installing Alternative Plug 1 Supplied 230 VAC Plug Cut cord close to plug. 2 Alternative Plug (230 VAC Plug Shown) 3 Input (Black Lead) (Brass) Terminal 4 Neutral (White Lead) (Brass) Terminal 5 Ground (Green) Terminal 6 Outer Shell 7 Cord Grip Strip cord jacket back enough to separate conductors. Strip conductors enough to make good contact with plug terminals. Make plug connections and reinstall outer shell and cord grip. Tighten assembly screws onto shell. Do not overtighten. Ref. 801 305-A / 801 611 This procedure is necessary if the unit is to be connected to a 208/230 VAC receptacle that requires a plug that is different from the supplied plug. Tools Needed: 1 6 7 2 3 4 5 1 Power Switch Place power switch in On position 2 Output Control Place output control in Gas/Air position. 3 Pressure Gauge 4 Gas/Air Pressure Adjustment Knob Adjust pressure to 75 psi (517 kPa) on pressure gauge by pulling and turning knob. Push knob in to lock setting. Select desired cutting output with Output Control. 4-12. Setting Gas/Air Pressure Ref. 803 219 / Ref. 803 221 2 Set Controls Turn On Gas/Air Supply Adjust Pressure On Unit Select Desired Amperage To Begin Cutting Set To 75 PSI (517 kPa) For Cutting Or 55 PSI (379 kPa) For Gouging Requires 90.120 PSI Supply (621.827 kPa) Setting Gas/Air Pressure Place Output Control in Gas/Air Set Position Power Switch On Rear of Unit 1 4 3 AIR/N2 90-120 psi . A complete Parts List is available at SECTION 5 . OPERATION 5-1. Controls 1 Output Control Use control to set cutting output. Place control in Gas/Air Set position to safely adjust gas/air pressure. Only gas/air circuit is activated. 2 Status Lights (See Section 6-2) 3 Power Light 4 Power Switch . The fan will normally run for approximately 5 seconds after power switch is placed in the Off position. 5 Pressure Gauge 6 Pressure Adjustment Knob 6 4 5 . At ambient temperatures below .5 C (23 F), readjustment of gas/air pressure regulator may be necessary (see Section 4-12). Use only clean, dry air with 90 to 120 psi (621 to 827 kPa) pressure. Prevent moisture from entering air supply at extreme cold temperatures. Ref. 211 048 2 3 1 5-2.

The cutting speed curve shows the recommended maximum cutting speed capabilities of the power source and torch for mild steel of various thickness. The best cut quality is achieved by cutting near the chart line. Cutting below the line (too slow) will result in excess dross. Cutting above the line (too fast) will cause blowback and lack of penetration. OM-926 Page 17 A complete Parts List is available at OM-926 Page 18 5-3. Trigger Safety Lock 1 Trigger 801 397-A 1 Trigger Locked Trigger Unlocked 801 400-B / Ref. 802 878 5-4. Plasma Cutting System Practices Pulling rather than pushing the torch makes cutting easier. Use a proper guide or template for accurate cutting operations. The pilot arc starts immediately when trigger is pressed. Maintain approximately a 90° angle to the workpiece surface for proper cutting results. Always connect work clamp to a clean, paint-free location on workpiece, as close to cutting area as possible. Set correct air pressure for process: 75 PSI (517 kPa) for cutting, 55 PSI (379 kPa) for gouging. 90° DO NOT start pilot arc without cutting or gouging as this shortens the service life of the nozzle and elec...
