PRODUCT DESCRIPTION The Invertec V300-PRO is a 300 amp arc welding power source that utilizes single or three phase input power to produce either constant voltage or constant current outputs. The V300-PRO is designed for 60 Hz supply systems. The welding response of the Invertec has been optimized for GMAW, SMAW, TIG and FCAW processes.
– – 8 – INPUT VOLTAGE SETUP POWER CORD CONNECTION A 10 ft. (3.0m) power cord is provided and wired into the machine. Follow the power cord connection instructions. Incorrect connection may result in equip- ment damage. Single Phase Input 1. Connect green lead to ground per U.
– 9 – – 9 – remote control adapter and K857 remote control are required for remote output control). 5. Set the meter polarity switch on the rear of the Invertec to coincide with wire feeder polarity used. The wire feeder will now display the welding volt- age.
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.
– 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.
– 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.
– 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.
– 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.
– 15 – TROUBLESHOO TING GUIDE Trouble What To Do Not output but fan operates and meter is on. Poor welding, weld settings drift, or output power is low. Main fuses open or Switch PC boards overheated. Output turns on momentarily then switches off and repeats.
