COMPACT AND VERSATILE TIG IMPULSE WELDING DEVICE

that is very close to laser welding in terms of working method and range of applications. On workpieces with a thickness of 0.2 mm or greater, it is an effortless process to produce robust welds.

The PUK 5.1 precision welding equipment puts a whole host of possible applications for jewellery production at your fingertips. Structures made from sheet or wire elements can be just as easily done as tack welds and repairs to jewellery parts, restoring missing parts or filling of pores by applying welding wire - and many more options, the PUK 5.1 is able to produce anything from the smallest of repairs to volume production, and even the most extraordinary of new creations.

FOR DAILY USE

PUK’S OPERATING PRINCIPLE IS AS SIMPLE AS IT IS INGENIOUS

As soon as the tip of the electrode of the welding hand piece touches the workpiece, the welding process starts automatically. At the contact point, under an inert gas atmosphere, a melting process with a diameter of between 0.3 and 3.0 mm takes place (depending on material and setting).

In addition to many precious metal alloys such as gold, silver and platinum, many non-ferrous metals such as copper and tin alloys, many steels, titanium and aluminium alloys are suitable for welding. All alloys suitable for laser or TIG welding can also be welded with the PUK 5.1.

• Intuitive to operate
• Thanks to intelligent pre-settings, only 2 operating steps are necessary. Select metal group and work situation > weld!

• Precision handpiece for precision welds
• Solid quality and the best materials such as stainless steel and Teflon are prerequisites for precision in manufacturing and reliability in application               

• Handling the components: Sophisticated details simplify handling.

Correctly set the device in two steps:

 1. Select metal group

 2. Select welding situation

• > weld!

• Power and welding time can be adjusted "blindly" according to individual need.
• You can continue to concentrate on the workpiece.

 Recommended setting range:

 A blue bar indicates the setting range recommended by our goldsmiths.

 The "red" range: 

• The red lines on the display warn you that you are outside of the sensible time or power range for the metal and welding situation selected.

Faster progress to better results – "blind operation" with single-handed operation. Concentration remains focused on the workpiece. 

Even higher-performance LED lighting in our new premium welding microscopes. More uniform illumination of the working area - more flexible use of the microscope. These microscopes can also be used as fully equipped workplace microscopes - not just for welding. 

Setting of parameters for "Power", "Time" and menu navigation with one single rotary controller. 

Individual device set-up using the settings menu, e.g. preselection of welding cycle, calling operating levels up on screen and hiding them again, e.g. program memory, expert level, tack welding ... 

Extremely simple touchscreen operation. Now with slide function! 

Preselection of two different welding cycles

NEW: MICRO-WELDING

The application range of the PUK 5.1 is further expanded with material thickness down to less than 0.2 mm allowing the welding of wires and sheets with even greater control.

NEW: SMOOTHING

Shorter repetition rates and serial pulses enable a continuous workflow. With this setting, the PUK offers the opportunity to shape the added material as desired and to significantly improve the welding characteristics of highly thermally conductive materials such as silver, copper and bronze. 

NEW: EXPANDED SELECTION OF METALS
Optimised welding parameters for copper and bronze. The PUK takes over full control despite the high thermal conductivity. 

• If you touch a button on the display for a longer period of time (approximately 2 seconds), a help window pops up in which the basic functions of the button are explained.

• Then touch the help window briefly to switch back to the operating menu.

• Using this process, two metal parts are bonded together at their contact point using resistance welding. 

• The parts can be "stuck" together so that they can then be finally attached using PUK welding or so that they can then be soldered. 

• The tack welding function is particularly well suited to processing metals with low electrical conductance. For example, steels, titanium, etc.

• Optimised "settings" menu
• Simplified menu navigation with one single rotary controller
• (De-)activation of the expert menu with 15 different welding curves
• (De-)activation of the program memory with 20 custom programs
• (De-)activation of the tack welding function
• (De-)activation of the micro menu
• The selection of basic functions such as lighting, welding sequence, choice of language or acoustic welding signal.
• Opening the gas valve for adjustiing the gas flow to the correct amount required

• Activate the foot switch by pressing it down for 3 seconds. The automatic function of the PUK is then deactivated.

• The white symbol top right on the display signals that foot switch operation is activated.

• Welding is then only triggered when you press the foot switch.
