The single-phase 230V 50/60Hz Minarcmig Adaptive 170 from Kemppi features a load capacity that is rated 170A at 25-per-cent duty cycle and 120A at 60-per-cent duty cycle. The OCV is 22-31V, while the maximum wire-feed speed is up to 12m/min. This lightweight, compact, ergonomically designed machine, with its sturdy casing and easy-to-carry handle, is suitable for MIG/MAG welding on site or in the workshop by welders carrying out thin-sheet-metal fabrication, installation and setup work, as well as general repair and maintenance work.  It is particularly suited to welding with ferrous and ferrous-flux cored wires with diameters of 0.6-1.0mm diameter fed from 200mm diameter spools. It is said to be very easy to use due to the adaptive-welding-parameter control, where the user only needs to select the thickness of the sheet and pull the welding-gun trigger. Minarcmig will automatically adjust to the correct welding parameters, while the MMG 20 welding gun is designed to help make the...

A feature of Kemppi's three-phase Mastertig MLS 3000 and 3003 AC/DC welding systems is the Microtack function, available on the optional ACX control panel. This function has been specifically developed to tack weld carbon, stainless steel and titanium thin sheet components up to around 4mm thickness. Microtack welding resembles spot welding in that it uses a high current pulse to create a low heat input to weld thin sheet materials and thin sheet to thicker sheet materials.  This method of TIG welding is made possible by the control technology used in the Kemppi power source, which creates a tailored current pulse that is efficient and fast, a matter of a few dozen milliseconds to create the low heat input. The result is a clean, small tack weld, which is similar to a laser weld in appearance and characteristics, resulting in lower risks in burn. Although Microtack welding is very fast and easy to use, it does not use any filler material and the heat input is low, so there is littl...
