Summary

2.1 Brief introduction

MIG145 / MIG185 / MIG225 / MIG255 / MIG295 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.
MIG145 / MIG185 / MIG225 / MIG255 / MIG295 machines Characteristics:
◆MCU control system, responds immediately to any changes.
◆High frequency and high voltage for arc igniting to ensure the success ratio of igniting arc.
◆Simple select material/wire diameter and the stored know-how controls the welding
process automatically
◆Lift TIG operation, If the tungsten electrode touches the workpiece when welding, the
current will drop to short-circuit current to protect tungsten.
◆ Intelligent protection: over-current, over-heat, when the mentioned problems 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.

2.2 Working principle

The working principle of MIG145 / MIG185 / MIG225 / MIG255 / MIG295 welding machines is
shown as the following figure. For example single-phase 230V work frequency AC is rectified into
DC(about 312V), 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.
