High Efficiency Switch Welder

Product Advantages

High Efficiency : Comparing to traditional solid state welder, save power for 15%-25%.
Less Area Covered : Saving 60% area than traditional solid state welder.
Easy installation : Comparing to the 5-7 days for traditional solid state welder installation, high efficiency switch welder installation is 1 day.
Less installation cost : For example 100kw solid state welder, the traditional welder installation cost is around USD800(purchasing cable, nozzles, cable bridge and brackets), moreover, welder room or elevated platform is necessary, all the cost will be about USD800-1600.
Welding quality : Benefitted from PWM precise control voltage and three level of filtering, the voltage output is stable, ripple coefficient is 50% lower than solid state welder. The welding quality is obviously better than traditional solid state welder.

Note: traditional solid state welder ripple coefficient is 4%, high efficiency switch welder is 2%.
