Efficient All-Rounder with Extended Functions

Fronius launches a new generation of the TransPocket MMA welding system:

Machine and plant construction, steel, metal and gantry engineering, in smithies and forges or in the workshop: most users are familiar with mobile power sources that deliver outstanding results with their different electrode types - even under tough conditions. One such solution is supplied by welding technology specialist Fronius, who recently launched a new generation of its proven single-phase MMA system: the TransPocket 150 and the TransPocket 180. The new design features simple operation and added functions. A digital resonance inverter ensures perfect weld properties in a whole range of applications. Thanks to the innovative PFC (Power Factor Correction) technology the handy, compact Fronius devices are also extremely energy efficient.

The two new TransPocket 150 and 180 models replace the tried and trusted TransPocket 1500, which has been on the market since 2001 and which has enjoyed great popularity with its many users in many industries. The power sources are supplied in different variants depending on their primary use. The TransPocket 180 is also the first single-phase MMA system in the Fronius portfolio with a welding current range of up to 180 amperes. The new models are primarily designed for manual metal arc welding and can handle rod electrodes with a diameter of up to 4.0 mm without difficulty. A special operating mode can be selected to ensure perfect welding results when using cellulose electrodes (CEL). New and enhanced dynamic settings let the user adjust the ignition precisely to the electrodes being used. The HotStart function makes it easier to ignite CEL- and rutile electrodes, the SoftStart option on the other hand ensures a stable arc for basic electrodes, which ignite at a low welding current.


Extended functions make even TIG welding possible

The latest device generation from Fronius is also suitable for TIG welding, for which we offer a new TMC connection (TIG Multi Connector) and a torch with the Up/Down function. The welding current can be adjusted by pressing a button on the welding torch, between 10 and 150 amperes for the TransPocket 150 and between 10 and 220 amperes for the TransPocket 180. With the TransPocket, TIG welding is carried out in two- and four-step mode or as pulse welding. The TAC tacking function is also available for quick and easy joining of thin gauge sheets without additional filler metals.

Whatever the welding process, the new TransPocket delivers excellent welding results. A real innovation here is the digital resonant intelligence developed by Fronius. The practically ideal starting characteristic ensures constant power reserves for an extremely stable arc with reduced energy consumption. This gives excellent ignition and weld properties, which are manifested above all through the optimised electrode ignition and minimised spattering during the welding process. The low short circuit current of around five amperes when the tip makes contact with the workpiece prevents the electrode from sticking. The current then rises to 35 amperes to ensure that the arc does not break, before the device reaches the target current, which the user can set precisely.


Energy efficient and flexible thanks to power factor correction

Another highlight of the new TransPocket generation is the PFC (Power Factor Correction) technology. This automated power factor correction models the input current such that it has an almost ideal sinusoidal progression. This reduces the reactive power to a minimum and uses the mains current optimally and effectively. The output current is also increased by harmonic smoothing. Compared to devices without PFC, this permits a greater welding current of up to 180 amperes with the same mains fuse protection. At the same time, Fronius technology provides greater stability during voltage fluctuations. With a tolerance of -20% / +15% the power sources are ideally designed for generator-powered operation and also deliver maximum power during major mains voltage fluctuations. They are protected against overvoltages of up to 400 volts - a major advantage for instance when the device is wrongly connected to a high voltage. Long mains leads of 100 meters and more are not a problem. This gives the user a larger action radius and more flexibility during welding.

The combination of digital resonant intelligence and PFC technology means that the new TransPocket is particularly energy efficient. In comparison to the predecessor model, the power consumption of the TransPocket 150 is up to 20 percent lower - with increased output power. The power consumption of the TransPocket 180 is actually 30 percent lower than that of comparable competitor devices. Users therefore benefit from far lower current consumption and can therefore lower their energy costs sustainably.

Fronius has also further optimised the design of the TransPocket. The power supply has a tough and sturdy plastic housing to guarantee reliable operation under the varied and often difficult usage conditions. With protection class IP 23, the sensitive electronics are safely shielded from dust and damp. A permanently integrated dust filter and improved cooling also help. A special arrangement of vents at the front of the housing prevents dirt from entering the device and optimises airflow. The airflow is directed only where cooling is required - i.e. to the transistors. The sensitive PC boards are therefore optimally protected from dust and dirt. Plastic feet prevent damage to the housing which can occur from being dragging along the floor, etc. Ergonomic handles make handling easier and welding power-leads are easily and conveniently wound onto the device.


Intuitive operation with flexible options

Intuitive operation is guaranteed by the innovative user interface with seven-segment display. The inset, angled display is optimally protected against mechanical damage and is easy to read in all lights. The user interface is simple and clearly laid out yet offers a wealth of settings options - from adjusting welding parameters by selecting special functions to reading off operating hours. The TransPocket can also be fitted with the optional TMC (TIG Multi Control). This allows the user to control the power source directly from its place of use. A service interface, also protected, allows simple analysis of system information and special characteristic updates. The improved housing design also ensures effortless maintenance of the devices.

Fronius also offers a multivoltage variant of the TransPocket 180, which is a single-phase device that can be operated flexibly with mains voltages of between 96 and 265 volts. This is a major benefit to users who access different mains supplies, e.g. in different countries. Thanks to their compact and resilient construction, the TransPocket is also the ideal companion for mobile use (e.g. on construction sites). Weighing just 6.3 kilograms (TransPocket 150) and/or 8.7 kilograms (TransPocket 180), the power sources are easily transported. The CE and S marks confirm the safety of the devices and ensure that they can be used even in environments with increased electrical danger, e.g. in confined spaces or in damp.


Bespoke service for optimum performance

To support users individually as far as possible, Fronius offers a wide range of services for the new TransPocket. Customers can simply hire the welding system on request. This gives them flexibility, saves costs and ensures that they remain at the cutting edge of welding technology. Fronius provides complete systems in the TransPocket 150 and 180 system case comprising the power source, welding station equipment and TIG torch, in a compact kit. If required, the welding specialist can perform additional tasks such as calibration, maintenance or safety inspections (SIT) of the devices. Bespoke maintenance contracts also guarantee maximum availability, planned downtimes and optimum value retention of the welding system.
