About Us: http://solution-welding.com/6-2-mid-frequency-inverter-resistance-welding.html

The mid frequency inverter can increase the frequency of a resistance transformer from 50/60Hz to 1000Hz to decrease the weight of its iron core, reduce secondary inductive losses and control energy and operating costs. It can be paired with automatic electrode-holders to form a portable and lightweight welding equipment set with excellent performance.

Features

The amount of splashing is largely decreased for a high quality weld and a clean, safe, and comfortable welding environment
Accurate control of welding parameters in 1 millisecond for the consistent welding results of multilayer steel plate, thick steel plate, high strength steel sheet and aluminum alloy
Basic building blocks of an inverter and in-process monitoring of weld quality and data monitoring
Stable welding control system to prevent weld defects
Three-phase electric power system and medium frequency welding
No capacitance compensation cabinet
Small volume and light weight. Compatible with suspension welders
HMI operator interface for easy operation
