Fronius's new generation of the TransPocket Stick (SMAW) welding machineClick image to enlarge

Fronius' new generation TransPocket 150 and 180 are replacements for the company's TransPocket 1500. The single phase stick welding machines feature the company's Power Factor Correction for energy efficiency.

The TransPocket 180 also means that, for the first time ever, a single-phase 180 A stick (SMAW) welding machine is available. The hand-held welding torches are designed primarily for stick welding and can utilize electrodes with diameters up to 4 mm (5/32 in.). This latest generation of power sources is also suitable for TIG welding up to 220 A, with a new TIG Multi Connector and a welding torch with an Up/Down Function at the user's disposal to adjust the welding current directly on the torch. Two-step and four-step TIG welding is possible with the TransPocket, as well as current pulsing.

A digital control adjusts the characteristics of the power source to suit the welding electrode. This results in outstanding weld properties that are evident in the welding process, primarily because the electrode ignition is optimized, with a lower short circuit current and reduced spattering.

High voltage reserves at each operating point enable very high levels of arc stability. Another genuine innovation is the PFD technology, which automatically adjusts the power factor. Doing so adjusts the current consumption by the power source to match the sinusoidal grid voltage, in turn reducing the current consumed by the power source. This makes the device energy efficient, and minimizes disruptive repercussions in relation to the grid. Long power leads are also an option.

Fronius has also further optimized the design of the TransPocket: With its stable and robust plastic housing, the device is suitable for use in all areas of application. The delicate electronics are protected from dust and moisture, thanks partly to a permanent dust filter and improved cooling. These prevent contamination to the sensitive PC board by ensuring the air flow is routed away from it. Ergonomic handles make the power source easy to carry, while the protected seven-segment display is easy to read regardless of the lighting conditions. The user interface is designed to be simple and intuitive, but still provides a variety of setting options. In addition to the protected service interface, which makes it easy to read out system information and update special characteristics, the optimized housing also makes it extremely easy to maintain.

A multi-voltage variant of the TransPocket 180 is also available. The ability to handle incoming voltages between 96 and 265 volts gives the user flexibility when operating the device. This is a major advantage when the available power changes from job site to job site. With its compact and hard-wearing structure, the TransPocket is also ideal for mobile use on construction sites.
