1. IGBT Control, 2. Can MIG/MAG, MMA, 3. Can work normally in input voltage range +15%~-20%, 4. Can save welding parameter - details see: https://www.machineto.com/multioperator-digital-igbt-mig-mag-co2-welder-welding-machine-10136623

Feature:

1.Digital control circuit, independent microcomputer database, make precise control from input to output.

2.One-knob control,only need to set the welding current,the welding voltage will automatically match with it precisely, can also adjust voltage finely. Can work with all kinds of automaton.

3.The welding parameter may intialize,memorize and load. There are10 group parameters, which can memorize when initalization or welding.One group parameter is including: welding voltage, welding current,crater voltage, welding wire diameter, welding wire type and welding gas and so on.

4.One machine with multi-functions, can satisfyMAG/MIGwelding (Suitable for welding such metal aslow carbon steel, stainless steel and aluminium.)

5.When input voltage range in+15%~-20%,it can work normally.
