TIG DynamicWire TIG Cold Wire Welding Made Easy

Active wire control in TIG cold wire welding

The innovative advantage of Fronius TIG DynamicWire, when compared to a conventional continuous wire feed in cold wire systems, lies in its automatic self-regulation.

The power source actively adjusts the wire speed to the welding behavior, torch position, and current conditions, even compensating automatically for component tolerances of up to 30%.

The result?

Perfect welds every time. Existing iWave cold wire systems can be easily upgraded with the patented TIG DynamicWire welding package through software activation.

TIG DynamicWire - Advantages

Greatly simplified handling

Unlike welding with a constant wirefeed, TIG DynamicWire and the dynamic wirefeed adapts to the welder, not the other way around.

Minimal training time

The simplified handling enables even less-experienced welders to quickly produce high-quality TIG welds.

Always the right wire speed

The dynamic wire feed system automatically adjusts the wire speed to the current conditions. This means that the optimum amount of wire is always available – without any manual adjustment.

Automatic compensation of component tolerances of up to 30%*

The self-regulating effect of our active wire control automatically compensates for component tolerances and changes in torch position.

*With a corner weld made of CrNi steel (1.4301 / X5CrNi18-10) and a material thickness of 10 mm, a gap bridging of 3 mm (30%) is achieved in the PA position.

Set just one parameter to start welding

Needing to set the wire and current parameters separately has become a thing of the past. Thanks to TIG SynergicMode, only one parameter has to be set, and the rest are applied automatically based on material-specific characteristics.

DynamicPen for maximum freedom

Use the decoupled cold wire feed system with DynamicPen and make your TIG welding work even more efficient, precise, and flexible.

Slim and ergonomic design for ease of use
Automatic wire control with voltage measurement
Uninterrupted welding without putting the pen down for maximum weld lengths
Manual and precise positioning of the wire
Automatic wire stop when the base material is touched
Best accessibility to components and perfect for narrow-gap applications
Suitable for demanding welding positions such as overhead work
Easily switch from standard cold wire feeding to DynamicPen
Also suitable for larger wire diameters (up to 1.6 mm)

TIG DynamicWire process

TIG DynamicWire is based on active control of the wire feed.

Thanks to the voltage measurement between the workpiece and the wire, the wire is dynamically fed in exactly the quantity that is needed at the moment. TIG DynamicWire works in synergic mode. Current and wire feed no longer have to be set separately.
