1 Spectrum Lynx 2 Power Plug 3 Engine-Driven Welding Generator With Required Receptacle Installed 4 AC Power Receptacle For Lynx Connect power plug to proper receptacle on engine-driven welding generator. 1 801 977-A / Ref. ST-802 200 Rear of Unit 2 3 4 Example Welding Generator OM-2219 Page 12 SECTION 3 – OPERATION If the welding generator includes a fine adjust control, be sure to set the control to maximum for full output control capacity. When using the Lynx, auxiliary power output is not available from the 120 or 240 VAC receptacles on the welding generator. NOTE 3-1. Controls Ref. ST-189 734 / Ref. 801 977–A 6 1 2 4 5 7 Rear of Unit 8 1 Gas/Air Pressure Gauge 2 Pilot Arc Switch Use switch to control pilot arc. Place switch in Expanded Metal position for continuous pilot arc. Use while cutting expanded metals only. The Expanded Metal position keeps the pilot arc in the circuit at all times. Life of consumables will be significantly reduced while in Expanded Metal mode. Place switch in Tip Saver position to provide pilot arc output for arc starting only. Use Tip Saver position in most applications to lengthen the life of the torch and its consumables, and to obtain maximum cutting performance. Torch trigger must be reset after every cut while in Tip Saver mode. 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 3-2). 4 Power Light Power light comes On when Power switch is placed in On position. 5 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. 6 Trouble Lights (see Section 4-3) 7 Gas/Air Pressure Adjustment Knob (see Section 3-2) 8 Power Switch 9 Door for Consumables Storage 9 3 OM-2219 Page 13 1 Output Control 2 Power Switch Place controls as indicated above. Only gas/ air circuit is activated when the Power switch is turned On with Output Control in Gas/Air Set position. 3 Gas/Air Pressure Adjustment Knob Pull knob and turn to adjust pressure. Push knob in to lock setting. Select desired cutting output with Output Control. 3-2. Setting Gas/Air Pressure Ref. 801 977-A / Ref. ST-801 976 1 Set Controls Turn On Gas/Air Supply Adjust Pressure On Unit Select Desired Amperage To Begin Cutting Set To 70 PSI Requires 90–150 PSI Supply Setting Gas/Air Pressure Place Output Control in Gas/Air Set Position Power Switch On Rear of Unit 2 3 3-3. Sequence Of Operation Put On Personal Safety Equipment After cutting arc starts, slowly start moving torch across metal. Adjust torch speed so sparks go thru metal and out bottom of cut. Pause briefly at end of cut before releasing trigger. Install & Connect Equipment EXAMPLE Of Cutting Operation ST-801 400-A Press trigger. Pilot arc starts. Postflow continues for approx. 20 to 30 seconds after releasing trigger; cutting arc can be instantly restarted during postflow by pressing trigger. Check Torch Tip, Electrode, And Retaining Cup Check Gas/Air Pressure Set Controls Begin Cutting Turn On Welding Generator The pilot arc starts immediately when trigger is pressed. Place drag shield on edge of metal, or allow correct standoff distance – approximately 1/8 in (3 mm). Do not clean torch by hitting it against a hard surface. Hitting hard surfaces can damage torch parts and stop proper operation. Inspect shield cup, tip, and electrode for wear before cutting or whenever cutting speed has been significantly reduced (see torch Owner’s Manual). Do not operate torch without a tip or electrode in place. 3-3. Sequence Of Operation Put On Personal Safety Equipment After cutting arc starts, slowly start moving torch across metal.
