FULLY DIGITAL MICROPROCESSOR INVERTER SEMIAUTOMATIC WELDERS 3 IN 1 |
||||
|
||||
1. PURPOSE OF USE |
||||
|
Fully digital microprocessor inverter welder 3 in 1 has the following welding modes: MMA, TIG AC/DC,TIG pulse AC/DC,
MIG adaptive, MIG pulse/double pulse (Argon, Mix). It is designed for welding of ferrous, unstainable and nonferrous metals.
Three-phase active power factor corrector (PFC) provides high stability and quality of welding. |
