MasterTig MLS

Diverse DC TIG welding. This product series offers devices of several power levels and a wide range of possibilities, and their sturdy construction can endure even the roughest handling.

A product series for many applications

The MasterTig MLS product series devices are compact and sturdy TIG welding inverters. They are suitable for TIG and MMA welding using DC current.

MasterTig MLS 2000 is a model that uses 1-phase current, which has a load capacity of up to 200 amps using a 30% duty cycle.

MasterTig MLS 3000 and 4000 are more powerful 3-phase current device models.

Mastertig MLS device packages using liquid-cooled TIG torches can be equipped with the new Kemppi MasterCool 10 cooling unit based on new HydroCool technology. Its functions are controlled from the power source control panel.

Reducing open-circuit voltage is possible by utilizing a purpose-built VRD accessory (voltage reduction device).

Functions for all DC TIG and MMA welding needs

The MasterTig MLS product series contains a range of four control panel options. The control panels utilize advanced Kemppi MLS technology (multi logic system) offering a wide array of features, which can be used to precisely control the arc and weld pool behavior in different environments and with different base materials.
