Welding System - Kemwelder IV
Rapid and reliable repairs in tool making and mould building
This welder is designed for mould and dye repair and this can help save you time and money by keeping mould repair in-house instead of sending out for service. It's very easy to use and nearly anyone can begin welding within a very short period of time. It's also mobile, so you can transport this around your company and weld any mould size, large or small and it utilises very little heat so you don't have to worry about heat distortion that you get from traditional TIG welders.
The welder works by gently touching the spot of the welding point with the electrode tip. After 2 seconds, the control unit triggers welding, at the same time, an electromagnet draws the electrode back. You then precisely position the electrode for subsequent points which can then be triggered every second. For safety, the shutter of the microscope closes with each weld.

- Product Code: 339102
- The amperage (TIG) has been increased by 15% to 720 A. This means you can now weld wires of up to Ø 1 mm
- Auto cooling system
- Improvements to handpeice
- New software monitors the welding process:
- Avoidance of welding errors due to interruption of the welding process in case of excessive pressure on the electrode
- Increased service life of the electrode tip
- Avoidance of tungsten inclusions on surfaces or on workpieces and materials that still need further processing
- Enhanced process reliability and more consistent quality
The microscope has many features that make welding easy. The 10 x magnification microscope has a built in integrated LED light uniformly which illuminates the entire welding area. The visual field is of adequate size with a diameter of 20 mm. When using the handpiece and welding filler, you can very accurately determine the spot where you wish to weld using the thin, pointed electrode. Using the hydraulic swivel arm, you can quickly position the microscope to exactly where needed.
The integrated LCD vision protection filter closes the beam path during the welding time that gives eye protection during the welding process. The whole process takes place in milliseconds.
The kemwelder has pre-set welding parameters for mould repair applications and this is going to make it much easier to select the correct setting for your welding application. You’ll have settings for three different metals; steel, aluminium and copper and four different welding wire diameters up to 0.8mm and then five different surface applications for flat, edge, corner, rib and three corner. So, at the touch of your fingertips, you have access to sixty different mould repair applications.

When welding with the Kemwelder, you must use argon gas to get the best results, the argon gas is going to eliminate oxidation and it is also going to give you clean welds. You will need a bottle of Argon 4.6, and the correct fillers for your material.

Welding rods for the Kemwelder
Only the right welding rods will ensure good results. You will get good results if the composition of the welding rod corresponds to your material. The rods are 333 mm long with a minimum weight of 100 grams. Coils available on request. Please contact us if you do not find the right rod for your application. Wires with a diameter of 0.8 mm welds the Kemwelder without any problems, and with good conditions even up to 1 mm.

Welding fumes extractor and filter
The advantages of working in an environment free of welding fumes and dust are significant. During welding operations, especially prolonged ones, the reliable extraction of welding fumes is crucial. Similarly, fine dust generated during grinding and other related activities should also be extracted to prevent inhalation of these substances. We have been diligently searching for a highly capable, efficient, and portable extraction solution, and we are pleased to introduce the Extractor III. This innovative device offers an impressively quiet and effective means of extracting fumes and dust, all at a remarkably affordable price. The Extractor III incorporates a brushless suction motor, which sets it apart from conventional extraction systems. This motor operates silently and boasts a remarkably long lifespan, contributing to the device's exceptional performance and reliability.
