Air cooled solid state ignitron tube replacement for resitance welding
250KVA Welding Transformer Size
1810 Welding Rating Amps RMA at 5% Duty Cycle
500 Welding Rating Amps RMA at 50% Duty Cycle
9000 SGL. Cycle Surge Current (ITSM)
2200 SCR Voltage Rating (PIV)(VRRM)
Convection cooled, at 45°C maximum ambient temperature.
Suggested transformer KVA is based on the maximum secondary voltage at 5% duty cycle, 460 Volt incoming A.C. line or higher; typically, spotwelding applications.
All switches are supplied with an encapsulated thermostat sensor, 50°C open on rise, and is isolated to base to 2000 Volts. Thermostat leads are 12 inches long.
Consult factory for seam, projection, or frequency converter welding requirements.
