With the Ignis Battery, Fronius introduces a new level of freedom in welding. This battery-powered version of the trusted Fronius Ignis delivers top-quality MMA welding without the need for a mains connection. Perfect for use on remote construction sites, in agriculture, off-road, or during urban assembly work, the Ignis Battery offers unmatched flexibility, durability, and reliability wherever they're needed most.

The Ignis Battery is available in the power category up to 150 A and combines state-of-the-art advanced welding electronics with intelligent battery technology. It supports both manual metal arc (MMA) and mobile TIG welding, delivering uncompromising quality, and compatible with all types of electrodes—rutile, basic, or CEL.

For professionals who want to work independently

Whether for pipeline construction, outdoor repairs, or assembly work, the Ignis Battery is a compact welding machine that combines power, mobility, and flexibility. Weighing just 12 kg (without battery charger) and featuring a compact, robust housing, it is the perfect companion for mobile use. With an IP23 safety class, stainless steel filter, and 3.5 cm ground clearance, it can withstand the most adverse conditions—from rain to dust, from heat to cold.

Intelligent battery technology—powerful, long-lasting, efficient 

In addition to voltage monitoring, an innovative battery management system oversees the charging process and protects against overcharging and deep discharge. The integrated high-performance lithium-ion battery (LiFePO4) with 750 Wh enables welding of up to 31 electrodes (2.5 mm) or up to 30 minutes of TIG welding at 100 A on one charge. If needed, the quick-charge function provides 80 per cent battery power in 40 minutes and a full charge in 60 minutes.

Simultaneous charging and welding

In hybrid mode, welding and charging from the grid can be carried out simultaneously, extending the operating time. The battery’s integrated power reserve ensures a stable arc even with fluctuating mains voltage. This means that the full output power of 150 A is always available—even with a 120 V grid.

If the Ignis Battery is used in generator-powered operation, a small 2 kVA generator is sufficient to provide the required welding power and arc quality. This makes transportation to the workplace easier and reduces noise pollution in the working environment. 

Sophisticated details for maximum performance

The Ignis Battery impresses with functions that make welding easier, safer, and more efficient. HotStart and SoftStart ensure optimum ignition for rutile, basic, or CEL electrodes. TrackingArc enables precise re-ignition of the arc at just 8 A — ideal when changing electrodes or at the end of welding. Anti-stick prevents electrode sticking, saving time and material. If you want to weld faster and still have attractive welds, you should choose MMA Pulse, which is particularly effective for out-of-position welding.

The Ignis Battery also has sophisticated technologies for TIG welding: e.g., TIG Pulse and Comfort Stop, which ensure controlled TIG welding with a perfect end-crater. Maximum compatibility is ensured thanks to the TIG-Multi Connector (TMC), which is a standardised connection for peripheral devices.

Conclusion: The perfect addition to the Fronius portfolio

Together with the Artis TIG welding machine series and Ignis MMA devices, Fronius now offers a complete range of mobile, reliable, and powerful welding solutions with the Ignis Battery— for all those who want to live out their passion for welding on the move and without restrictions.
