FRONIUS IGNIS 250 INVERTER MMA
FRONIUS IGNIS 250
Inverter MMA Power Source with TIG DC
Part number: 4.075.255 Includes: 4m electrode cable & 3m earth cable
The Fronius Ignis 250 tops out the Ignis range, pairing the highest output of the family with built-in TIG DC welding — giving crews stick and TIG capability from a single portable inverter. Like the rest of the range, it's designed for construction sites, maintenance and repair work, agricultural applications, and home workshops, delivering a stable arc even with long lead lengths, generator power or fluctuating grid voltage.
Ready to weld straight out of the box, the Ignis 250 package comes complete with a 4m electrode cable and 3m earth cable, so there's no need to source cables separately before getting started.

| Grid tolerance | Stable arc performance with grid leads up to 100m and on generator power |
| Efficiency | Integrated PFC (Power Factor Correction) for energy-efficient, low-interference operation |
| Display | 7-segment display, intuitive operating concept |
| Housing | Robust construction with integrated stainless steel filter for outdoor/site use |
| Country-specific versions | Available for regions with different mains voltages |
TIG Built In, No Upgrade Required
Unlike the Ignis 150 and 180 — where TIG DC is only available on separate TIG-specific versions — the Ignis 250 includes TIG DC welding with Comfort Stop as standard. That makes it the natural pick for anyone who needs both stick and TIG from one machine without having to select a specific TIG variant. It also carries the extended TIG functions available across the TIG-capable Ignis range, including TAC tacking, TIG Pulse, and the TIG Multi Connector system for compatible torches and remote controls.
Why Choose the Ignis 250?
Two processes, one machine. With stick and TIG DC covered from a single power source, the Ignis 250 removes the need to choose or upgrade to a TIG-specific variant — it's ready for both from the outset.
Top of the range output. The highest-output model in the Ignis family, suited to heavier stick electrode work as well as precision TIG applications.
Goes anywhere, works everywhere. Built for unstable grids, long cable runs and generator-powered sites, the Ignis 250 delivers a consistent arc in conditions that would compromise a standard inverter.
Ready out of the box. With the electrode and earth cables included, there's no separate cable sourcing required before the machine can be put to work.
Frequently Asked Questions
What welding processes does the Ignis 250 support? Manual (stick/MMA) electrode, CEL electrode, and TIG DC with Comfort Stop — all included as standard, without needing a separate TIG version.
Does the Ignis 250 come with cables included? Yes — the package includes a 4m electrode cable and a 3m earth cable, ready to weld on arrival.
Does the Ignis 250 need a separate TIG version? No. Unlike the Ignis 150 and 180, TIG DC with Comfort Stop is built into the Ignis 250 as standard.
What extra TIG functions does the Ignis 250 offer? As part of the TIG-capable Ignis range, it supports TAC tacking, TIG Pulse and the TIG Multi Connector system for compatible torches and remote controls.
How does the Ignis 250 compare to the Ignis 150 and 180? All three share the same portable, site-ready design and grid tolerance. The 250 sits at the top of the range with the highest output and standard TIG DC capability, while the 150 and 180 are MMA-focused unless a TIG version is selected.
How well does the Ignis 250 handle unstable power or long cable runs? The Ignis is built for exactly this scenario — integrated PFC technology and its inverter design maintain a stable arc with grid leads up to 100 metres and on generator power, making it well suited to remote or unreliable-power sites.
