Today’s common denominator in the industry is productivity. Many companies are pondering on means to solve the productivity equation ” also when it comes to welding. Automation is usually off ered as the productivity solution. However, welding today and also in the future is mostly manual work. On this basis, Kemppi has for years now studied the potential for increasing manual welding profi tability. Kemppi ProNews 1 • 2008 3 The new MasterTig MLS 3000/3003 ACDC product from Kemppi is a versatile TIG welding solution tailored particularly for use in aluminium and stainless steel welding. 4 Kemppi ProNews 1 • 2008 INNOVATION This feature is particularly suited to demanding jobs where the materials to be joined are thin sheet or have diff erent thicknesses. Strong but barely noticeable tacks ensure high-quality welds Kemppi has released its new three-phase MicroTack resembles spot welding in that it provides a sudden high-current pulse, which fuses the materials to MasterTig MLS™ 3000/3003 ACDC welding each other. This feature is particularly suited to demanding solutions for TIG and MMA welding. The new jobs where the materials to be joined are thin sheet or have MasterTig machines off er welders some really different thicknesses. The superiority of the MicroTack tacking method is based enjoyable features, like MicroTack™ and MIX on its ease of use and very low heat input. Thanks to these TIG. characteristics, the weld spots remain small and of equal size and do not cause deformation of the welded materials. Tack welding refers to joining pieces together with small, spot-like welds before the primary welding. While this MicroTack facilitates welding mechanisation phase is usually necessary in welding work, tack welds In the development of the new MasterTig machines, often slow down the solid welding and increase the risk of Kemppi has worked in collaboration with Rämö Oy, an welding errors. engineering works based in Imatra, Finland. The features of In particular, in welding of thin materials, tack welds can the machines were studied there in a real-world demanding burn through readily or remain raised or bumpy, thus environment, and the functions have been tuned to meet appearing as a defect in the quality of the end product. real user needs. Excessive heat input in the tacking stage, on the other Tommi Äikää, who is in charge of the metal sheet hand, may twist the work pieces and leave air gaps between production at the Rämö machine works, explains how them. the MicroTack tacking feature has improved weld quality and reduced welding errors particularly in mechanised MicroTack revolutionises tack welding welding. Kemppi has developed the tack welder’s dream function, “Previously we used normal TIG welding for tacking, MicroTack, which is available in the MasterTig MLS and that worked just fi ne, as well. Now, however, 3000/3003 ACDC welding solutions released this spring. we have partly adopted mechanised welding The function makes even diffi cult welding tasks a pleasure, in longitudinal welding, and thus the as Tuomo Mattila, head of the MasterTig product accuracy requirements for sheet- development team, puts it. metal work have become much “The highly positive comments on the MicroTack feature stricter,” Äikää explains. have greatly delighted us.

The method is yield signifi cant savings.” excellent for mechanised welding, as tacking spots made with MicroTack cannot be detected in the fi nished product, MasterTig is the ’horn of plenty’ of welding nor are there any holes burned by the large tack weld caps. features Äikää emphasises the speed of MicroTack tacking and “Although MicroTack has become the top feature of the new MicroTack tacking the time saved, which directly contributes to increased MasterTig machines, it is still just one good feature among results in small, evenly profi tability. many others. One must bear in mind that, as a whole, these sized tack welds in He says: “For example, we weld the perpendicular bars of machines represent the defi nite state of the art of AC TIG demanding jobs, paper machines, which can be up to 13 metres long.
