BIG POWER FROM A SMALL PACKAGE


N


ew from Kemppi and weighing at just 14.2 kg, the MinarcMig Evo welding machines are


designed and built to meet the distinct needs of welders on the move, combining the convenience of a portable and lightweight design with high-performance MIG/MAG welding capabilities. Every welder develops unique methods


and skills through years of dedicated learning. The new MinarcMig Evo welding machines seamlessly integrate significant MIG/MAG welding capacity and top-tier quality into a small portable machine that caters to a wide range of projects. MinarcMig Evo 200 offers Automatic and


Manual mode set-up for precise welding quality and arc ignition, monitored and


controlled by Kemppi’s adaptive arc regulation system. MinarcMig Evo 170 offers manual setting only, with separate controls for voltage and wire feed speed. Each model features a large graphical interface that guides the user during setup. With the MinarcMig Evo 200 you simply set the plate thickness and weld, and you can select the material type, which includes ferrous, stainless steel, aluminium and CuSi brazing filler wires, for wide variety of industrial applications. These little giants deliver portable MIG/MAG welding power, offering 200 A or 170 A at a 35% duty cycle from a 240 V single-phase mains supply. PFC power source technology offers


ultimate energy economy with a power factor of 0.99. MinarcMig Evo can also

hat’s the advantages of the flexible Lorch MicorTIG welding units. These welding units stand


out with their compact, lightweight housing and excellent performance no matter the power supply. They offer the greatest flexibility and serve as the ultimate, fully functional TIG welding units for mobile use. The amperometric digital display and


clearly structured user interface allow intuitive yet highly precise operation. An operation concept with a graphic display can be added as an option as well. TIG ignition works contactless with


high-voltage pulses applied at the touch of a button even in battery-powered operation. Since the tungsten electrode does not touch the workpiece, the weld seam will not be contaminated while the electrode remains protected. The integrated pulse and fast pulse


function at up to 5 kHz is particularly suitable for processing thin welding sheets. It permits outstanding weld pool control for perfect results


even at difficult welding tasks. The job function saves parameters


for up to 10 welding tasks and quickly recalls them when required to complete recurring tasks quickly and efficiently. Lorch MicorTIG welding units can be


used for any type of electrode. They offer a convenient pre-selection for CEL and standard electrodes and can even handle special electrodes easily. The arc-force control comes in when welding, ensuring arc stability and perfect material transition. The electrode will not stick or anneal due to the anti-stick-system. The patented MicorBoost technology


provides enormous voltage reserves to adjust the TIG arc in an outstandingly stable, controlled, and precise manner even at fluctuating mains voltages. This makes welding at up to 200 A possible on a regular outlet. With MicorBoost technology, Lorch welding equipment can be made even lighter and more compact while ensuring increased power output. Conventional welding inverters have relatively few voltage reserves. Whenever

the arc becomes unstable during electrode welding, the conventional inverter has too little power to stabilize and the arc energy briefly collapses. This reduces the average arc power. MicorBoost technology provides huge voltage reserves. The collapse is avoided or decisively shortened and the arc power increases. This enables quality welding that is extremely stable and controllable, even with a long drawn arc.

be used efficiently with extra-long power supply cables exceeding 100 m in length, allowing for optimum welding utility for site welding environments. The new MinarcMig models come


‘equipped ready to weld’ with the Flexlite GC welding gun. This gun features integrated cable bending support and an innovative gun handle, ensuring optimal handling and control.
