1. GENERAL DESCRIPTION. TECHNICAL CHARACTERISTICS.
The SMART 400 MMA are single-phase electronic technology appliances (INVERTER) designed for use as a
continuous current source for coated electrode and TIG DC welding process. Their descending characteristic
permits excellent arc stability both in the TIG and in the electrode welding processes. t. These equipments have
a protection system, which means they can be installed, without any danger of failures, in low quality supply
networks and electrical generating sets.
