2.1. Electric and magnetic eld
The working principle of MIG SERIES arc welding machine is shown as the following
single-phase 110V/220V work frequency AC is recti ed into DC, then is converted to medium
frequency AC by inverter device (IGBT), after reducing voltage by medium transformer (the main
transformer) and rectifying by medium frequency recti er (fast recovery diodes), and is outputted by
inductance
ltering. when MIG. Meanwhile, the welding current parameter can be adjusted
continuously and in nitely to meet with the requirements of welding craft.

2.2. Volt-Ampere characteristic
MIG SERIES welding machine has an excellent volt-ampere characteristic, whose graph is shown as the
following gure. The relation between the rated loading voltage U and welding current I is as follows:
U =14+0.05I (V).
