LN-9 GMA Connection Instructions 1. Turn the Invertec power switch “off”. 2. Connect the K596 control cable assembly from the LN-9 GMA to the Invertec control cable connector. The control cable connector is located at the rear of the Invertec. 3. Connect the electrode cable to the output terminal of polarity required by electrode. Connect the w[...]

– 11 – OPERA TING INSTR UCTIONS DUTY CYCLE The Invertec is rated at 300 amps, 60% duty cycle for 3 phase inputs (based on a 10 minute cycle). It is also rated at 250 amps, 100% duty cycle. CONTROL FUNCTION / OPERATION Power Switch - Place the lever in the “ON” position to energize the machine. When the power is on, the digi- tal meter will [...]

– CV FCAW This setting has been optimized for Innershield ® and Outershield ® flux-cored electrodes. CV GMAW Short circuit, glob and spray transfer solid wire and gas welding are done in this mode. Low end procedures, less than 17V, may operate better in the FCAW mode. Voltage in the GMAW mode can become erratic when welding is attempted using [...]

– 13 – Meter Polarity Switch The wire feeder polarity switch is located at the rear of the machine. The switch provides a work connection for wire feeder voltmeters. Place the switch in the position of the electrode polarity indicated by the decal. The switch does not change the welding polarity. Auxiliary Power A 24 VAC @ 1 amp supply is inclu[...]

– 14 – PERIODIC MAINTENANCE Overload Protection The machine is electrically protected from producing high output currents. Should the output current exceed 340-360A, an electronic protection circuit will reduce the current to approximately 150A. The machine will continue to produce this low current until the protection circuit is reset. Reset o[...]
