of the Invention An improved welding system is shown. A single high capacity power supply (10) provides operating power for several weld selector stations (16). Each weld selector station (16) operates independently, is adjustable, and allows a welder to obtain the voltage and current characteristics desired for his particular welding operation. Each weld selector station (16) operates over a wide range of input voltages so that long runs of low-voltage interconnecting cable (14,15) can be used without adversely affecting the quality of the weld. Furthermore, the weld selector station (16) is small, lightweight and easily transportable. The result is a more efficient, less expensive, versatile welding system.
