Diode Based DC ARC Welding

Have any questions ?



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
