Three-Phase Rectified DC Spot Welder | ¡@ |
SRA04B |
High mains power factor & low magnetic impedance, reduce power demand. | |
Balanced load distribution on the three phases. | |
|
The hardened & ground hollow ram is
guided by sets of antifriction bearings. The ram combined with coil spring providing rapid follow-up motion. |
Digital format pre-setting & synchronous welding control ensure consistent & precise welding. | |
Synchronous SCR contactor with protection thermostat. | |
