1. Digital control circuit, 2. Can be MIG/MAG,MMA,TIG - details see: https://www.machineto.com/digital-igbt-inverter-mig-mag-welding-machine-10136666

Feature:

1.Digital control circuit, independent microcomputer database, make precise control from input to output.
2.One-knob control, only need set the welding current, the welding voltage will exact matching automatically, can also adjust voltage finely. Can work with all kinds of automaton.
3.The welding parameter may initialize, memory, load and lock. There are 30 group parameters, which can memorize or lock when initialization or welding. One group parameter including: Welding voltage, welding current, crater voltage, crater current, welding wire diameter, welding wire type and welding gas and so on.
4.One machine multiprocess, can satisfy MAG/MIG and MMA and TIG welding.
5.When input voltage range in +15%~-20%can normal work.
6. Apply to the welding in such trades as shipbuilding, metal structure, pipeline engineering, pressure container and vehicle making.
