Spot Welding Devices

Precise spot welding of multiphase steels (e.g. DUAL, TRIP, BORON STEEL, BDK), materials with differing thermal conductivity levels, high-strength mould hardened components and coated sheets.

Intelligent paramter management for process security

software updates + online service center for future security

THE SUPREME ADVANTAGE: maximum productivity and efficiency through especially long running times. Overheating is impossible! The precise cooling of the entire device right up to the electrode tip plays a major role in the quality of the welding spot and guarantees long electrode life.

CONSISTENT AND SECURED WELDING IN CONTINUAL OPERATION

Consistently high welding current power is guaranteed by the high performance inverter (as used in car assembly) and prevents drops in performance! Buffer circuit compensation immediately levels out any mains current falls.

TIME SAVINGS and SECURITY OF INVESTMENT

The preset parameters from the automotive manufacturer can be called up via the digital software control using the memory key. Plant time and energy frequencies for differing materials can be reprogrammed at any time by means of a simple update.

INTELLIGENT ADJUSTMENT

Permanent, digital weld spot monitoring automatically identifies any resistance fluctuations and disruptive factors (e.g. paint residues, adhesive, low pressure, or electrode soiling) and reacts with automatic welding parameter adjustment. This guarantees a continuous working process and uniform quality from the first to the last spot weld.

PROTON E+ all benefits of digital technology

The even more advanced version of the proven success-model PROTON E. A byword for the very highest welding performance and user-friendliness. Thanks to its four connector points, there is never any need to change cables when working with the pincer-type spot-welding gun, or in single-sided poker welding.

Spot-welding in its most perfect form

The Proton family “looks good” right the way through – not just on the surface. They have been rigorously designed to fulfil clearly defined requirements. Their controls, for instance, have been reduced to a limited number of task-related zones, and systematically arranged. Also, the machines’ recessed contours mean that the controls are completely protected. No matter how rough things get in the auto-body shop, the FAN Proton stays literally unshakeable – thanks also to its sturdy plastic housing.

You’ll also love the direct twin connection. This means that when you’re working with the pneumatic spot-welding gun or making single-sided spot-welds, you no longer need to change cables.

A final word on the subject of operator convenience: The trolley, the gun holder, the tool tray and the integral air cooling system are “standard extras” that will all make your job a lot easier.

Economy

Less means more

The cutting-edge technology from FAN optimises the welding output. 100% efficiency, yet reduced electricity consumption. Also, less fuse protection is needed, and it is no longer necessary to re-work the weld spots. The new modular structure is also ideal, as it makes it very easy to exchange spare parts.

FAN Austria give you a 10-year supply guarantee on all spares, and a full two-year warranty on the electronics and the power section.

Safety

Maximum safety is all part of the package

For us at FAN Austria, safety is an absolute must. Every machine comes with the CE mark as standard. Also included with every Multiworker: The S mark and the IP 21 approval mark for protection against water and foreign bodies.

Welding properties

You know a good thing when you see it

The FAN Multiworker Proton machines incorporate a whole host of great practical features – maximum power, minimum consumption, and superb welding properties. All machines come with the laser and double-weld pulsing function as standard. As you would expect when concentrated power and top technology come together in one single machine.

Everything under control

With a FAN Multiworker Proton, nothing is left to chance. Everything is exactly monitored and controlled. “Welding management” is what some people call this. The air-cooling control, for example, is a standard integral feature of every single machine. Another inclusive feature is the automatic weld-spot monitor, for both acoustic and optical monitoring. With features like these, there’s nothing left to go wrong! Every weld spot is just right.

The digital microprocessor control is simply ideal for the auto-body repair field, because it lets you regulate each spot weld individually. This also permits the power and time frequencies to be programmed exactly to factory specification, precisely fine-tuned to any type of bodywork and any sheet thickness. What is more, once you have your optimised values, the new memory function enables you to reproduce them again and again. Before you even start work, the latest factory data are at your fingertips, stored in the machine. Now that’s “welding management” for you! For us, a whole lot more than a nice-sounding buzzword.

Built for highest demands. The integrated double cooling significantly increases the duty ration and ensures permanent cooling of the spot welding tongs, cables, connectors and the transformer

General

Proven innovation

The auto-repair industry is looking forward: An innovation from FAN Austria has won itself an enviable track record – spot-welding using digital technology. A development that owes its proven success to an integrated microprocessor control. This makes it possible to tailor the welding spot completely individually. Also, the respective power and time frequencies can all be programmed, making it possible to reproduce them exactly again and again. Not only that, but the microprocessor control increases efficiency many times over.

Utilisation

Welcome everywhere

The machines of the Multiworker PROTON series are reckoned to be the first-ever intelligent spot-welding machines with digital weld-spot programming and a memory function. This makes it possible to replicate the original factory spot-welds on the bodywork.

High quality standards such as these are only possible thanks to our close cooperation with the automobile industry. Working together with the manufacturers, we test and define which welding machines and processes are best suited to the type of material in question. Given today’s increasing tendency to combine materials such as high and higher-strength steels, this is an approach which is becoming ever more important. This is why we at FAN go a step further and also offer practicable and user-friendly repair concepts to go with our machines.

PROTON Sair – the ultimate in spot welding

The air-cooled version of the innovative PROTON S. Exceptionally powerful, thanks to its revolutionary patented technology – the Digital Power Module (DPM). The process underlying DPM is called wavesplitting. A digital addressing control ensures that all 3 phases are subjected to equal loading. Maximum power, yet with a low fuse rating – this achieves optimum efficiency. Power at its purest.

Even on 3.4 and 5.0 mm thick sheets, the PROTON S AIR makes welding-spots whose quality is in no way inferior to that of spot-welded joints made by conventional inverter units.

Handling

Anything goes

Working with the new generation of Multiworker machines is a real pleasure. A Multiworker Proton, you see, is a universal genius. To take just one example, it lets you do single-sided spot-welding on sheets of up to 2 + 2 mm thick, and double-sided spot welding on sheets of up to 2 x 4 mm thick – made possible by the FAN Celect II and Celect lll pneumatic spot-welding guns.

What is more, the system lets you use all the techniques currently needed in the auto-body field. With the right accessories, y ou have a huge repertoire of “tricks” at your disposal. Just look at this list of all the things the FAN Multiworker Proton can do for you:

Welding processes and techniques:

• Carbon electrode — for shrinking auto-body panels

• Washers, rivets and nails — for straightening body work panels

• Multimat-welding — pneumatic spot-welding gun

• Single-sided spot-welding with energy laser

• Pulsed-power welding — double-weld pulsing function

• Spot weld bonding

• Repairing hail damage with Pullflex
