T 450

Fully Thyristorised D.C Welder T-Series is a combination of high quality performance, site worthy construction and sleek good looks. Apart from a D.C. Manual welder, T-Series is an excellent machine for D.C. TIG Welding with suitable accessories.

  • Ideal constant current power source for manual (MMA) / TIG Welding
  • Unique continuous control of ARC force from soft to hard penetrating arc.
  • Guaranteed ARC striking with any type of electrode upto a distance of 100 meters (Electrode + Ground cable). Cable length drop compensated.
  • Smooth, Stable ARC with very low ripple for consistent X-Ray quality welding.
  • Compact, lightweight power source for easy maneuverability – incorporating latest international design & production technique.
  • Advanced quick response protective circuits.
  • Easy to repair and maintain
