Welding Without A Lazer

Description of Operation Elements and Functioning:

          (ON-OFF Switch,  Output Switch, Hand Piece, Welding Table, Clamp, Optic Unit and Microscope)

• The only elements you operate are the ON-OFF switch and an 8 level output switch.

• To work with the welding device you will need the hand piece with a clamped electrode, the welding table and clamp plus the optic unit for eye protection.

• When welding using the PUK, please remember these important points in order to achieve optimal results.

• Always work with a sharp electrode. Always grind or exchange the electrode if the tip is burned out or broken.  Exchanging or grinding the electrode is often necessary if the user does not have much practice with the device.

• During welding, make sure your hands are resting and kept steady.  Always avoid free-hand welding.

• Also important during welding is to make sure that the work piece has optimal electrical contact to the welding table. If this is not possible, use a clamp.

• For welding itself, you must touch the electrode tip to the welding point but without too much pressure. This is very important!  Maintain this contact until the welding is complete. 

• The welding process ends automatically and the user does not require any further action. Shortly before welding stops, you will hear a signal tone. You can stop welding at any time before you hear the tone by ending electrode tip contact with the welding point.

• To ensure optimal welding results you should always use a suitable protective gas. We recommend argon protective gas with a more than 99% purity. For example the conventional quality of “Argon 4.6â€‌.  When using protective gas, it is important not to set the flow-through amount too high. 4 litres per minute is normally sufficient.  Only in welding situations where the electrode must be clamped for a longer period of time – for instance welding difficult to reach spots – it can be helpful to set a higher flow-through amount. 

• Before an unpracticed user begins welding a piece for the first time we recommend trying some test welding, since welding results and quality depend on several factors.

• Different metals or alloys react very differently during welding.  Metal characteristics such as conductivity, melting points and small amounts of alloy that may escape can greatly influence the welding results. 

• The welding results you receive and the size and depth of welding points all depend on the above factors and not on the strength of material used. 

• Generally note that metals that are well-suited for welding based on their physical characteristics also produce good results when welded using the PUK 111 Spot Welding Device.

How to operate

• The PUK111 is a small, easy-to-handle automatic spot welding device with many advantages.
• It can be used to position small welding points very precisely, even in deep, hard to get to positions. This makes the PUK111 especially suitable for fixing work pieces prior to soldering.
• Using the electrode clamped in the hand piece, welding points from 0.7 to 2.0 mm in diameter can be fixed. Starting from the point of contact, the arc is lighted and can be precisely controlled by the device during the short burning time.
• The heat created by the arc is very low. So work pieces can be easily hand held. Temperatures are similar to heat created during laser welding. 8 program settings set energy and impulse periods, easily adjustable with a level switch on the device. 

• By using a protective gas during welding, oxidation is largely avoided, this allows the work piece to be processed further without any additional treatment. Results are welding points with maximum homogeneity and a smooth as silk feel. 

• Welding is possible for all precious metals and precious metal alloys, including stainless steel and titanium, as well as bronze, copper and tin alloys.

• In general, all metals that are well-suited for arc welding are also suitable for PUK111 welding.

• In addition to fix welding, it’s also easy to melt ball shapes, weld loops, close pores or weld smaller joints.  This lets you create stable and long-lasting connections, especially in places where soldering is not possible.
• Devices are manufactured according to VDE guidelines and the standard requirements needed for CE certification.
