Advantages

tigSpeed – high process reliability and welding

speed, very easy handling

 Perfectly controllable weld pool, even with posi-

tional welding (e.g. vertical-up position)

 Especially high welding speeds – similar to MIG/MAG

welding, but with low emissions and no spatter

 Reduced heat input, minimised distortion, less

shrinkage of the workpiece and optimised impact

work-values

 Reduces welder fatigue thanks to easier handling

and more comfortable working positions

tigSpeed with hot wire – higher deposition rate and

minimised risk of seam errors

Reproducible welding results thanks to digital control

 Set and view all parameters

 Forward/backward motion frequency (in nitely

adjustable from 1 to 16 Hz, or disable)

 Wire feed speed (0.3 m/min to 10m/min)

 Program number (de ne and save 15 individual weld-

ing programs)

 Switch between m/min and ipm

 Key switch

Welding speed comparison in cm/min:

Position PF: Manual TIG with 3.2mm  ller wire; TIG cold wire + tigSpeed and hot wire + tigSpeed with 1.0mm  ller wire

TIG hot and cold wire welding

Dynamic wire feed system

 Up to 100% faster in comparison to manual TIG welding

 Up to 60% reduction of dilution

 Perfect weld appearance, no weld spatters

 Adjustable heat input in the wire from 40A to 180A
