FRONIUS ARTIS 300 GAS/F DC INVERTER
FRONIUS ARTIS 300
Inverter Power Source — TIG DC & Manual Electrode
3-year warranty when registered
The Fronius Artis 300 tops out the Artis range with up to 300A output, bringing professional-grade TIG DC and MMA control to a compact, mobile inverter platform. It's available in both gas-cooled and water-cooled configurations, with XT versions offering extended mains voltage flexibility for use across almost any power supply worldwide — from standard single-phase workshop power through to 600V industrial grids.
Like the rest of the Artis line, the 300 focuses on making the most efficient use of available input voltage, keeping it reliable and productive whether it's running in the workshop or out on generator power at a remote site.

Gas-Cooled & Water-Cooled Packages Available
The Artis 300 is offered across several package configurations to suit different applications and mains supply situations:
- Artis 300 DC/G — gas-cooled, standard mains voltage
- Artis 300 DC/G/XT — gas-cooled, extended (XT) mains voltage range for worldwide use
- Artis 300 DC/W — water-cooled, standard mains voltage, for higher duty-cycle and extended production work
- Artis 300 DC/W/XT — water-cooled with extended (XT) mains voltage range
The XT versions add a higher output characteristic curve and CEL compatibility on top of the extended voltage tolerance, making them well suited to export, mixed-power-supply sites, or workshops that need one machine to work reliably across different grids.
TIG & MMA Welding Functions
The Artis 300 carries the full function set of the Artis range, including:
- TIG Comfort Stop — automatic current shutdown after a set change in arc length, for clean, crater-free finishes
- TAC function — pulses the weld pool to cut tacking time by up to 50%, with minimal to no temper colours
- TIG Pulse — 1–990 Hz pulse range for thin sheet and tight-space welding
- Touch HF & HF ignition — precise arc starts, including contact-based ignition for triggerless torches
- Spot and stitch welding — even-interval spot welding with adjustable stitch pause
- MMA and CEL welding — full stick electrode capability including cellulose electrodes
- MMA Pulse — improved weld properties in tight spaces and better gap-bridging on vertical-up seams
- HotStart, Anti-stick & Arc-force dynamic — easier ignition, prevention of electrode sticking, and stable arc on underloaded basic electrodes
- TrackingArc — low-amperage arc for locating the exact restart position after an electrode change, reducing under-filled craters and rework
- Adjustable time shutdown/standby mode — reduces energy use when the machine is idle
Why Choose the Artis 300?
Top of the Artis range. With up to 300A output and the fullest duty-cycle rating in the line, the Artis 300 handles heavier TIG and MMA work than the 170 or 210 while staying in the same portable, compact format.
Cooling and voltage to match the application. Gas or water cooling, standard or XT extended-voltage — the Artis 300 range covers workshop, site and export power scenarios from the one platform.
Full professional function set. TAC tacking, TrackingArc, MMA Pulse and TIG Comfort Stop bring the same control found on larger industrial systems into a compact, mobile machine.
Reliable wherever the power comes from. Fully generator-compatible, with XT versions extending that reliability across a wide voltage range for genuinely worldwide use.
Backed for the long run. A 3-year warranty is available simply by registering the machine.
Frequently Asked Questions
Is the Artis 300 gas-cooled or water-cooled? Both — it's available as the gas-cooled DC/G or DC/G/XT, and the water-cooled DC/W or DC/W/XT, so cooling can be matched to duty cycle and application.
What is the XT version of the Artis 300? XT versions extend mains voltage compatibility from 200 to 600V for use on almost any grid worldwide, and add a higher output characteristic curve plus CEL electrode compatibility.
What's the duty cycle of the Artis 300? 40% at 300A, rising to 60% at 260A and 100% at 230A (measured over 10 minutes at 40°C ambient).
What welding processes does the Artis 300 support? TIG DC and manual (stick/MMA) electrode welding, including CEL electrodes.
Does the Artis 300 come with a warranty? Yes — a 3-year warranty applies when the machine is registered.
Is the Artis 300 generator compatible? Yes, it's fully generator-compatible, making it suitable for remote or off-grid site work.
How does the Artis 300 differ from the Artis 210? The Artis 300 offers higher output (up to 300A vs 210A), is available water-cooled as well as gas-cooled, and includes extended XT functionality not offered on the smaller models.
