Fronius Fortis
The next-gen manual MIG/MAG welding machine
MIG/MAG welding with the Fortis
As flexible as your work
Welding tasks are often a challenge, especially for small and medium-sized companies. Some of the tasks change on a daily basis, as do the required welding processes. This calls for a welding machine that can be adapted perfectly to these dynamic conditions.
With up to 240 optimized characteristics that have been specially developed for the requirements of steel construction, the Fortis series impresses with its reliable welding performance. In addition to steel, the MIG/MAG welding machine also masters materials such as aluminum and stainless steel effortlessly, especially in combination with the pulsed arc.
Highlights of the Fortis
Sophisticated device concept
The overall design of the Fortis is based on a compact system with a maximum output current of up to 500 A.
Space for the optional cooling circuit is also provided in the housing, enabling space-saving setup and use, even in environments with limited space.
In addition to the Compact version, models with an external wirefeeder are also available to extend the operating range.
The all-in-one system: one device, countless possibilities
- Compact welding machines up to 500 A
- Retrofitting of water cooling for 320, 400, 500 A versions possible at any time
- Split versions with external wirefeeder for an extended operating range
- Duo version: compact welding machines from 320 A can be combined with an additional wirefeeder
- One user interface for all versions

The MIG/MAG welding functions
Welding Packages and software options
Standard
The Fortis Standard package allows you to weld all common materials reliably and efficiently across the entire power range, from root passes and thin sheets to thicker sheets.
Pulse
The Fortis Pulse package uses the pulsed arc for clean and efficient welding. It ensures minimal spattering and flexibility on thin to thick sheets.
Pulse/Standard
The best of both worlds at a set price.
Software options
- Duo: For Fortis 320, 400, and 500 Compact
- Jobs: For all Fortis power categories
- Documentation: For all Fortis power categories
- Trial: Available for all Fortis devices ex works for 10 h arc time
- Pulse/Standard Mix: Ideal for vertical-up seams
MIG/MAG, TIG, and MMA welding
TIG pulse welding
Pulse welding is used primarily for welding in tight spaces or for welding particularly thin materials. The result is an improved seam appearance.
Touchdown ignition
As an alternative to high frequency ignition, highly accurate touchdown ignition helps to improve user-friendliness. In addition, there are no restrictions in terms of the area of application.
TAC tacking function
Pulse currents are used to make the weld pool oscillate. This makes it easier to tack components together and reduces tacking time. The pulsed arc optimizes the process on very thin materials.
HotStart
The HotStart function was specially developed for welding with rutile and cellulose electrodes. In order to make the electrode easier to ignite, the current is increased for a split second during ignition on the welding machine.
Anti-stick
If a short circuit occurs (electrode sticks during electrode welding), the welding process is interrupted. This prevents electrode burn-out and/or serious weld defects.
Dynamic
If basic electrodes are welded with coarse droplet material transfer at a low current (underloaded), there is a danger of sticking. When the arc-force dynamic is set accordingly, the electrode burns freely, preventing sticking.
CEL (XT versions only)
When using cellulose electrodes (CEL), a specially selectable operating mode ensures perfect welding results.
Operating the Fortis welding machine
Simple, clear, customizable
The display is divided into three segments and is operated using the three rotary and push buttons below it. These can be used to adjust the main parameters and two custom parameters.
All important working and welding parameters are also visible on the first menu level. Dynamic visualizations, animations, and the status LED provide additional support for the user.
Intuitive menu navigation
Welding parameter wizard
This reduce errors, rejects, and rework while significantly increasing efficiency and quality.
The welding parameter wizard is indispensable, especially for tasks with constantly changing variables. The self-explanatory graphics make it easier to understand the settings so that even complex tasks can be mastered with ease.

The future is in your hands
Minimize welding errors
The clear user interface and welding parameter wizard in particular assist the welder throughout the entire welding process. This minimizes errors and improves the welding quality, reducing the reject rate.
Recycle instead of disposal
Thanks to the new housing concept, a significant proportion of the plastic components have been replaced by recyclable aluminum. As a result, we have increased the proportion of recyclable material to a total of 53%. The majority of the components can therefore be recycled and help to conserve natural resources.
Fix it, don’t pitch it
The easy accessibility of the components, especially the mains cable and connection panel, makes repairs quick and easy, which minimizes downtime. The high proportion of replaceable components also enables the devices to be used for a long time.
Save electricity with the XT version
The Fortis XT version is perfect for anyone who wants to save even more power. It boasts a higher power factor, making it 16% more energy-efficient than conventional versions.
FAQs: Fortis versus TransSteel
“Trans…” (derived from transistor) has been a part of our naming system for over 40 years. We are now setting new standards by renaming the successor generation of the TransSteel as Fortis. The name Fortis stands for strength, stamina, and flexibility.
We are presenting the Fortis in a completely new industrial design for the very first time. Our development work on the new housing centered on welding specialists and their needs, so user-friendliness and improved ergonomics were the key focus for us.
You can also see a major change from the outside: the new design highlights the durability of the Fortis in conjunction with a streamlined look. The color layout has been completely changed, further enhancing the devices’ visual profile and making them easier to recognize.
- Compact device design in 400/500 A power category
- XT versions in all power categories
- Plain text display with wizard and dynamic visualizations in over 30 languages
- Multiprocess also available for 400/500 A power categories (only for compact devices)
- Duo configuration available for 320-500 A power categories
- Connectivity as standard (WiFi and Bluetooth as standard, NFC optional)
- Welding Packages and software options
- New system components (wirefeeders, trolleys, remote controls, and more) and new manual welding torches
“XT” stands for “extended”. The XT versions offer an extended range of functions and were so named due to the repositioning of these models on the market. These functions include:
- 200-600 V continuous input voltage range (-10 / +6 %)
- Full generator compatibility
- Energy-saving due to the higher power factor compared to the 3-x-400 V version
“s” stands for “smart and steel”— smart operation and smart welding with a focus on steel applications, a particular strength of the Fortis. Of course, the Fortis can handle many other materials.
Our new series is a technical innovation, so existing TransSteel components are not compatible with the new Fortis.
New components and hardware interfaces are also available with the new design. With regard to welding torches, all FSC welding torches can be used through to the U/D functionality. Poti, JobMaster, and PullMig do not work with the Fortis.
