Perfect Welding


The TransPocket is available in power categories 150 to 480 A. In addition to the almost indestructible housing and cutting-edge technology, the TransPocket also has numerous functions that simplify work for the user: HotStart, SoftStart and anti-stick provide support at the start of and during the welding process.
Please choose your desired product.

The TransPocket 2500 is a completely digitally-controlled MMA power source with resonant intelligence. The ideal characteristic ensures a constantly stable arc, even with mains leads up to 100 metres long. Stability is also guaranteed with fluctuating mains voltages (340 to 506 V) and during generator-powered operation. The TransPocket 2500 welds all electrode types up to 5 mm, including the vertical-down welding of cellulose electrodes. It is extremely robust yet also small, light and portable.

The SoftStart function ensures a stable arc at the start of welding and was specially developed for electrodes that are welded with a low welding current (basic electrodes).


If a short circuit occurs that causes the electrode to stick during MMA welding, the power source is switched off immediately. This prevents the electrode from burning out.


To make the electrode easier to ignite, the current at the power source is increased for a fraction of a second during ignition. The HotStart function was specially developed for welding with rutile and Cel electrodes.

No grid-voltage dependence

The power sources are available in country-specific variants, meaning they can also be used in regions with differing mains voltages. For more information, please contact your local Fronius contact.
