Controls for Resistance Welding |
Once you have determined what kind of power transformer will be used for providing welding current to the welding tools,
you then select an appropriate welding control type. There are five types of welding controls as listed below and described
in this presentation. There may be other types (example MFAC) however these five are the most common.

Weld Control Types |
Low Frequency (50/60Hz) Single Phase AC/DC
Mid Frequency (400 - 2000 Hz) to DC
Low Frequency (50/60Hz) Three Phase to DC
Low Frequency (50/60Hz) Three Phase to Ultra Low Halfwave Frequency
Low Frequency (50/60Hz) Three Phase to Ultra Low Fullwave Frequency
