MIG

SERIES

EQUIPMENT

R221,R231,R251,R311 MIG welding machines adopts the latest pulse width modulation
(PWM) technology and insulated gate bipolar transistor (IGBT) power module, which can
change work frequency to medium frequency so as to replace the traditional hulking work
frequency transformer with the cabinet medium frequency transformer. Thus, its characterized
with portable, small size, light weight, low consumption and etc.

1.1 Brief Introduction

◆

MCU control system, responds immediately to any changes.

◆

High frequency and high voltage for arc igniting to ensure the success ratio of igniting arc.

◆

Lift TIG operation, If the tungsten electrode touches the workpiece when welding,

the current will drop to short-circuit current to protect tungsten.

◆

Simple select material/wire diameter and the stored know-how controls the welding

process automatically

Summary

1.2 Working Principle

230V

The working principle of R221/R231/R251/R311 welding machines is shown as the

following figure. Single-phase 230V work frequency AC is rectified into DC(about 312

V), then is converted to medium frequency AC (about 20-40KHz) by inverter device (IGBT

module), after reducing voltage by medium transformer (the main transformer) and

rectifying by medium frequency rectifier (fast recovery diodes),then is outputted DC .The

circuit adopts current feedback control technology to insure current output stably.

Meanwhile, the welding current parameter can be adjusted continuously and steplessly to

meet the requirements of welding craft.

◆

occoured, the alarm lamp on the front panel will be on and the output current will
be cut off. It can self-protect and prolong the using life.

Intelligent protection: over-current, over-heat, when the mentioned problems
