50 KVA LORS TECNA ROCKER TYPE SPOTWELDER MODEL 4608NA        S/N 11/2000       NEW 2000   KVA ........................................... 50 VOLTAGE ....................................... 440 SECONDARY VOLTAGE ............................. 4.2 MAXIMUM WELDING CURRENY ON STEEL .............. 12 THROAT DEPTH .................................. 9" MAXIMUM SHORT CIRCUIT ......................... 15 ELECTRO FORCE @ 87 PSI ........................ 528 LBS. STROKE ........................................ 1-3/4" - 3-1/4" HOLDER DIAMETER ............................... 1" ARM DIAMETER .................................. 1.575"   MACHINE WEIGHT: 270 LBS.   MACHINE IS EQUIPPED WITH: - TE-90 microprocessor welding control unit for single-phase resistance welders. The welding control unit is used to control the welder components and in particular, the thyristor adjusting the welding current. The TE-90 working cycle is described through 12 programming parameters. • Synchronous thyristor drive, phase shift control for welding current adjustment. • Simplified programming by means of four push-buttons. • Twin pre-setting for time and current, recallable by two independent controls. • Slope and pulse functions. • Single and automatic (repeat) operating mode. • Secondary current compensation function for the welding of oxidized sheets and rods. • First phase shift delay adjustment. It enables the machine line current best balance. • Control of solenoid valve 24 Vdc 7.2 W Max with protected output against short circuits. • "Watch-dog" safety circuit stopping the welder in case of control unit faulty operation, micro-interruptions or too high voltage drop.   FOR MORE INFORMATION: Call Rick at 973-497-7560
