Wide variety of materials suitable for welding, in particular aluminum, copper, heat quickly, poor weldability of the material can be obtained very good welding. In addition, multi-layer steel galvanized sheets and general welding, the welding quality is much higher than normal frequency welder.

Product Features

● SCR control accuracy is the traditional type of resistance welding machine more than 20 times, the secondary current output capability, waveform straight, almost no spatter during welding, solder joint surface quality.

● Three-phase load balancing, reduce impact on the grid to meet the requirements of preferential electricity rates; power factor up to 0.9 or more, and the welding time is short, significant energy saving.

● Low power requirements for the workshop, only the traditional SCR third of secondary rectification welding machine. Since a substantial increase in the welding current effective value, the actual welding time is reduced by 20%, while greatly reducing the welding pressure needs.

● High-speed microprocessors, the use of intelligent optimization calculation method, thus improving the overall stability of the welding.

● secondary current loop control, more precise control of speed actual welding current.

● from a pressurized welding cycle, preheat, ramp, welding a cooling one, welding 2, cooling 2, welding 3, slow down, cooling 3, tempering, maintenance, stop timing, etc., but also has the function of multi-pulse, can be full of a variety of materials, welding process requirements.

● interface using large LCD screen with the British side to switch the display, the operation is very friendly and in line with international trends.

● Connect with automated access products, system fault diagnosis, and display for easy maintenance.
