Compact and versatile TIG impulse welding device

On workpieces with a thickness of down to 0.2 mm or even less it is a simple process to produce high-quality welds. That way welding spots with a diameter of approx. 0.2 mm up to more than 3.5 mm can be set (depending on material and setting).

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 takes place.

In addition to many sorts of steel, different alloys of titanium, aluminum, copper and tin, as well as various precious metals and alloys are suitable for welding. Generally, all alloys suitable for laser or TIG welding can also be welded with the PUK U5. If necessary, welding wires can easily be fed or added.

• 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!

• Setting of welding parameters with a single rotary controller
• I.e. 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 engineers.

• 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.

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.

Preselection of two different welding cycles.

Speed function (only PUK U5+) – increased heat input into the workpiece for an improved welding performance when welding on highly conductive metals and alloys (e.g. copper).

NEW: MICRO MODE
Controlled welding process when welding on material thicknesses below 0.2 mm on wires and sheet metal with lowest and precise dosing and impact of the welding energy.

OPTIMISED MATERIAL PRESELECTIONS FOR THE INDUSTRIAL FIELD OF APPLICATION
Preadjusted welding parameters for a wide variety of weldable metals and alloys (such as stainless steel, Hastelloy, various precious metals, titanium and much more).

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!

• 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 resistance welding function
• (De-)activation of the micro mode
• 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

• 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.

• Corresponding equipment has to be connected to the socket for the foot switch.

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

• To respond to specific material conditions, various welding waveforms can be selected.

• 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.

• Actively cooled (only U5+)
  The PUK U5+ is actively cooled as necessary, and can be used in continous operation.

• High-performance welding handpiece (only U5+)
  optimized welding performance, maximum transfer of power.
