D.C. WELDING RECTIFIER

SUN SHINE Series of welding rectifiers are forced air cooled, silicon type and are designed o provide a D.C. welding current where 3 phase, 50 Hz A.C. Mains power is available at voltage ranging from 380 to 440 volt series of welding rectifiers are suitable for manual arc welding particularly in the welding of : 

1) Mild steel and low alloy steel at site where welds of high radiorgraphic standard are required.
2) Mild steel and low alloy in lighter guage resisting steel i.e., Stainless  steel.
3) Low allow and corrosion, heat and creep.
4) Non-ferrous metals.
5) Pipes in all positions.
These rectifiers can be supplied with a suitable Ammeter and Voltmeter for direct reading of the welding current and voltage and remote control device at extra cost.
