Sherman MTM  251 inverter welder / 4R  MIG / MAG DC MMA TIG MOSFET MTM 

This is Sherman welder 251 which is a compact MTM purpose inverter device made in MOSFET technology.  
It is used for welding of steels and non-ferrous metal coated electrode (MMA method), TIG, and MIG / MAG welding using a standard welding torch for MIG / MAG and handle Spool-type gun. It allows the MIG / MAG welding with the use of standard wire in the protective gases and the self-shielded flux cored wires. 
The device is equipped with a professional four-wire feed roller with variable speed regulation, smooth adjustment of the welding voltage in MIG / MAG welding current and MMA welding and TIG welding, as well as the Ionizing non-contact arc ignition in TIG welding. 
It is adjustable rise and fall delay of the current and the gas. Switch also has a two-stroke engine. 
Displays current / welding voltage, and adjusting the inductance of the welding of thin and thick parts.  Cooperates with coils of wire K-200 (5kg) and K300 (15) kg.
