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.
Thanks to the new housing concept, a significant proportion of the plastic components have been replaced by recyclable aluminum.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.
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.
A true all-rounder. XT stands for Extended, as the Fortis Extended version is designed for mains voltages from 200 to 600 V and can therefore be used around the world. Depending on the power category and the mains fuse, up to 320 A is possible in single-phase operation.
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.
“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.
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.
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.
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.
