More Power for TIG DC Welding
The Artis 300 DC XT from Fronius International extends the amp range for the product family, delivering more power, improved user-friendliness, and an extended XT version for worldwide use.
Both Artis 300 DC XT versions – the Artis 300 DC W XT (water-cooled) and Artis 300 DC G XT (gas-cooled) welders are available in the USA.
Consistent with its design, the Artis 300 DC XT uses numerous TIG functions to support professional-grade, high-quality welds.
Whether it’s used for pipe maintenance, handrail installation, machine repair, or hot water tank production, the Artis 300 DC XT is ideal for small and medium-sized companies with a wide range of stainless steel welding applications.
With this latest addition to the Artis series, manual TIG welding with up to 300 amps is now possible. “The new Artis is the logical expansion of the Artis series and is specially tailored to users with higher power requirements,” said Michael Eisterhuber, Product Line Manager at Fronius International.
Wide range of functions and user-friendliness

The Artis 300 combines all the functions of the more compact model and supports perfect weld quality and a high-quality seam appearance.
These include TIG pulse welding up to 990 Hz, the TAC tacking function, spot and stitch welding, trigger mode, setting options for the gas pre-flow time and gas post-flow, and touch high-frequency ignition for difficult accessibility.
If required, the Artis is also suitable for electrode welding, making it a real all-arounder.
To make the most of all the advantages of the Artis 300 in everyday welding, the device is equipped with an optimized control panel that is easy to use even when wearing gloves.
Five EasyJob buttons allow important welding parameters to be saved, making recurring welds easier. An additional favorites button makes the most important background parameters available in just one step.
During welding, the clear welding current display enables precise control of the entire process.
Wide range of variants: water-cooled and can be used worldwide
The Artis is available in a wide range of variants and can be adapted to individual requirements.
A new addition is a dedicated welding machine variant with integrated water cooling. A new stepper motor pump concept and built-in temperature sensors make the device particularly energy-efficient, with cooling only starting when it is actually needed.
This makes it a strong alternative to the familiar gas-cooled version. “Water-cooled devices are often more popular in the upper amp range, as the handle of the torch is slightly narrower and therefore fits better in your hand,” explains Eisterhuber, adding: “This is just a matter of a welder’s preference. In terms of quality, there are no differences between gas-cooled and water-cooled Fronius systems.”
Regardless of the type of cooling, the Artis is also available in an extended XT version, which enables single-phase 230 V use up to 300 A and can be used worldwide thanks to the large input voltage range of 200 to 600 V on 3 phase.
The new Artis 300 DC XT is the perfect addition to the Fronius TIG welding portfolio.
Together with the iWave, which is suitable for aluminum welding, Fronius covers both everyday welding tasks and tougher challenges.
While the Artis series supports TIG DC welding, the iWave is designed for TIG AC/DC and for industrial applications.
The iWave can be used for both automation and robotic welding. Additional features such as CycleTIG and TIG DynamicWire round off the range of special TIG functions.
