Techpro series of Welding Rectifier are forced air cooled silicon type. Comgination of well designed rectifier & transductor unit gives smo th and steady arc with minimum spatter & excellent weld bead. It gives ideal DC power source for Manual Metal Arc and Tungsten InertGas (TIG) welding.
Features :
* Most rugged & heavy duty machine
* Ideal for site & Construction purpose
* Easy arc Striking with all types of electrodes
* Easy for maintenance
