GENERAL DESCRIPTION
This welding machine is composed of the inverter MIG welder power supply with invariable voltage output
external characteristics manufactured with advanced IGBT inverter technology designed by our company. With
high-power component IGBT, the inverter convert the DC voltage, which is rectified from input 50Hz/60Hz AC
voltage, to high-frequency 20KHz AC voltage; as a consequence, the voltage is transformed and rectified. The
features of this machine are as follows:
⚫
IGBT inverter technology, current control, high quality, stable performance;
⚫
Closed feedback
circuit, invariable voltage output, great ability of balance voltage up to ±15%;
⚫
Electron reactor control, stable welding, little splash, deep molten pool, excellent welding bead shaping;
⚫
Welding voltage can be preset, and the voltmeter displays the preset voltage value when not welding.
⚫
Both welding current and welding voltage can be observed at the same time.
⚫
Slow wire feeding during arc starting, remove the melting ball after welding
,
reliable arc starting;
⚫
Wire feeding part is separated from the welding machine, wide welding operation range.
⚫
Small-sized, light-weighed, easy to operate, economical, practical.

Operating environment
Adequate ventilation is required to provide proper cooling for the machine. Ensure that the machine is placed
on a stable level surface where clean cool air can easily flow through the unit. The machine has electrical
components and control circuit boards which will be damaged by excessive dust and dirt, so a clean operating
environment is essential
