TransPocket 4000 Cel


The TransPocket 4000 Cel has an output of 380 A. Fully digitised, it guarantees unique reproducibility of the weld result and multiprocess capability. The power source is completely compatible with cellulose, including in the vertical down seam position. The main areas of application for the device include construction sites, shipyards, workshops and pipeline construction. The TransPocket 4000 Cel is suitable for all electrode types (basic, rutile, cellulose), for the most common materials (steel, aluminium, CrNi) and for carbon gouging, gouging and TIG welding.

    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.
