/ New design makes it even more robust / Light weight and handle as standard make it portable / Resonant Intelligence: ideal characteristic ensures stable arc, even with mains supply leads of up to 100 metres or in the case of fluctuating mains voltages (342 to 506V). Undervoltage shutdown not until 250V! / Optimum welding properties for all types of electrode (rutile, basic) up to 5mm – even vertical-down compatible welding for cellulose electrodes (diameters 2.5 mm upwards) / Improved arc force control means smoother and more accurate arc / Easy to use on site
