TransPocket TIG

The TIG series of the TransPocket is available in the 150 to 350 A power categories. Thanks to their additional functions, they make work easier for the user: with the TIG Comfort Stop, it is possible to prevent annoying arc breaks at the end of welding. The TIG pulsed-arc function ensures better control of the weld pool during out-of-position welding and when bridging gaps. A gas-test function has also been provided.
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 or fluctuating mains voltages (340 to 506 V) and during generator-powered operation.

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.


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).


With TAC, one spot is all it takes for tacking, because the pulsed arc sets the two weld pools in motion, making them jump together in next to no time, to make one single weld-pool. The TAC function is also very useful when welding light-gauge sheets without filler metal.

TIG Comfort Stop

At the end of the welding operation, the welding current is switched off automatically if a specific change is made to the arc length. This prevents the arc being unnecessarily elongated when the TIG welding torch is lifted off the workpiece to end the welding process. This results in a better weld result in the area of the end-crater, as the gas shield is maintained.

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.
