Medium Frequency Welding Transformer

Medium Frequency Welding Transformer

Our medium frequency welding transformer is designed to produce a small pulsating direct current for the welding of different metal materials, particularly those with high thermal conductivity like copper, aluminum, aluminum alloy, resulting in welds with the desired flatness and uniformly distributed interface.

Features
  • Three-phase electric power system with the power factor of nearly 1 can reduce power consumption and save energy
  • Small volume and light weight: 1/3 weight of common alternating current transformer for easy installation
  • Low demand for power supply system can save the cost of installing electrical auxiliary equipment
