WS-IGBT series inverter DC argon arc welding machineDetailed product description：

The WS-IGBT series inverter DC argon arc welding machine is an inverter DC pulse argon arc welding machine that uses IGBT as the switching element. This series of welding machines is an inverter DC argon arc welding machine that uses insulated gate power transistors (IGBT) as switching elements. Firstly, the 50Hz three-phase 380V power frequency input voltage is rectified and filtered into a DC voltage; Then, it is converted into high-frequency AC voltage through power electronic switches, stepped down by transformers, and finally rectified and filtered into a DC welding voltage suitable for welding process requirements. Control and regulate the output current through pulse width modulation (PWM) technology. Due to the use of switch power inverter technology, the weight and volume of the welding machine have been significantly reduced, and the efficiency has been improved. This series of welding machines has the following characteristics: stability, reliability, lightweight, energy-saving, and no electromagnetic noise. This series of welding machines is a DC argon arc welding machine, which can also be used as a DC welding rod arc welding machine, with multiple uses per machine. When performing argon arc welding, the ignition system adopts high-frequency oscillation, which is reliable and stable.

This series of welding machines is easy to start the arc, with continuously adjustable functions for welding current, thrust current, current decay time, and gas delay time. The arc extinguishing characteristics are stable, achieving the best results in both weld formation and internal quality.
When used for electrode arc welding, it can provide a more concentrated and stable arc. During droplet short-circuit transition, the reaction between the electrode and the workpiece is more rapid after a short circuit occurs.
This series of welding machines is particularly suitable for applications that require high welding quality, such as bicycles, stainless steel pipe industry, dairy processing industry, boiler and pipeline construction industry, etc. One machine with multiple uses can save equipment costs.
