FastMig™ Basic Models

Lightweight and powerful equipment for basic MIG/MAG welding. The detachable wire feed unit provides reach and the digital display improves control.

Basic power for MIG/MAG welding

FastMig Basic equipment is intended for basic needs of heavy and medium-heavy industry MIG/MAG welding. The equipment includes the power source, a detachable wirde feed unit, and the transport unit. In addition, a cooling unit is available for liquid-cooled welding guns.

Adjustment of welding settings is done conveniently and accurately using the stepless control knobs and a clear digital display.

FastMig KM 300, 400 and 500 power source maximum load capacities are 300, 400, and 500A. They are lightweight and energy conserving devices.

Wire feeders MF 29 and MF 33 are units designed for demanding conditions. Their dual-wall casing endures even harsh conditions, and wire feed is always steady and trouble-free.

FastCool 10 cooling unit is available for liguid-cooled welding guns.


Individuality through modularity

FastMig Basic product line power sources, wire feeders, and the cooling unit are inter-compatible, so the product selection always has the right and customized solution for all MIG/MAG heavy-metal industry basic welding needs.

The MVU-labelled multi-voltage power source models can be used in 3-phase networks with another current than 400 V.
