30% less spatter in steel welding

30% less spatter in steel welding

WiseSteel tackles the challenges of globular arc range by alternating between short arc and spray transfer. In short-circuit transfer, it improves the arc stability adaptively, providing better out-of-position steel welding capabilities. In spray transfer mode, micropulsing of current and voltage increases travel speed significantly.

Intelligent narrow gap welding

Intelligent narrow gap welding

Reducing the groove angle can add significantly to the efficiency and productivity of welding of heavy metal structures. Kemppi’s solution, Reduced Gap Technology (RGT), allows reliable and efficient narrow gap welding with no need for special equipment or accessories for material thicknesses of up to 30 mm. WisePenetration+ is needed to enable the use of RGT with the X5 FastMig. The function ensures weld penetration regardless of variation in stick-out length and keeps the welding current stabilized in all situations by actively adjusting the wire feed.

Cable Calibration

Cable Calibration

Quality assurance begins even before the arc ignites. Welding cable calibration compensates for cable voltage losses and keeps the arc voltage constant regardless of cable length. X5 FastMig has a built-in cable calibration function. The calibration must be repeated every time when you change the length of interconnection cable, earth return cable, subfeeder cable or welding gun cable.

PowerLog

PowerLog

PowerLog feature allows three alternative power level steps during welding, using the standard gun trigger to select the power step as your work demands.

A multi-process welding machine for challenging applications

A skilled and experienced welder can handle different kinds of material, welding applications and positions – even in demanding conditions. However, it is not only the skills that count – without appropriate high-quality welding equipment, excellent welds are only a dream. The performance of a welding machine also has a direct impact on the time spent on welding tasks. Significant cost-savings are only possible when work is done in minimal time with maximum results.
