Water cooled solid state ignitron tube replacement for resitance welding
300KVA Welding Transformer Size
1800 Amps RMS at 50% Duty Cycle
11200 SGL. Cycle Surge Current (ITSM)
2200 SCR Voltage Rating (PIV)(VRRM)
Amps RMS is achieved with a cooling flow rate of 1.2 gallons (4.5 liters) per minute at 40°C water temperature.
Fits 3/8 inch hoses.
Suggested transformer KVA is based on the maximum secondary voltage at 50% 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.
