Connecting Work Clamp And Gas/Air Supply Ref. 803 640-A / 802 201-B 1 Work Clamp 2 Workpiece Connect work clamp to a clean, paint-free location on workpiece, as close to cutting area as possible. Use only clean, dry air supply with 90 to 150 psi pressure. Torch requires 80 psi pressure. 3 Gas/Air Inlet Opening 4 Hose Use hose with an inside diameter of at least 3/8 in. If hose is over 40 ft (12.2 m) in length, use hose with 1/2 in inside diameter. 5 Teflon Tape Obtain hose with 1/4 NPT righthand thread fitting. Wrap threads with teflon tape (optional) or apply pipe sealant, and install fitting in opening. Route hose to gas/air supply. Adjust gas/air pressure according to Section 4-2.

OPERATION 1 Gas/Air Pressure Gauge 2 Gas/Air Pressure Adjustment Knob 3 Output Control Use control to set cutting output. Gas/air automatically flows at the set pressure. Use Gas/Air Set area of control range for setting gas/air pressure (see Section 4-2). 4 Trouble Lights (see Section 5-2) Power light comes On when Power switch is placed in On position. 5 Power Light 6 Ready Light Ready light comes On when unit is On to indicate that all safety shutdown systems are okay. If Ready light does not come On, check trouble lights. 7 Trigger Hold Switch To cut without holding torch trigger, depress upper end of Trigger Hold switch, press trigger to pilot, transfer torch to work, and release torch trigger within five seconds. To stop cutting, press and release trigger. When lower end of Trigger Hold switch is depressed, trigger must be held closed while cutting. 8 Torch Quick-Disconnect Connector 9 Power Switch 10 Door for Consumables Storage 4-1.
