25% faster welding

WiseFusion produces a very narrow and energy-dense arc that allows welding at a significantly higher speed without the risk of undercut. WiseFusion is up to 25% faster than conventional synergic 1-MIG and pulsed MIG, and it also facilitates weld pool control in position welding. Adaptive arc length regulation eliminates the need for constant parameter adjustment.

Optimized arc control

The X5 FastMig’s precise ignition and stable arc control produce high-quality welds. The latest ignition technology, Touch Sense Ignition, is featured as standard in all available models. It minimizes spatter and reduces the need for after-treatment. Arc control can be further optimized with optional welding programs and Wise special processes.

Built to last

The X5 FastMig is protected with a robust, injection-molded plastic casing that will absorb the knocks of welding life and guarantees uninterrupted welding. The wire feeder's graphical display panel is impact-resistant and will withstand challenging conditions.

Effortless operation

The X5 FastMig's operating basics are easy to adopt within 10 minutes. The wire feeder’s sturdy rotate-and-push buttons can be handled effortlessly, even with thick welding gloves on. Excellent usability increases valuable arc-on time, especially in companies that employ an outsourced workforce and where the welding fleet is shared.

Automated accuracy

Graphical 5.7” TFT screen panel displays all the needed information clearly without abbreviations. Welding parameters are set automatically by only adjusting wire feed speed. Memory channels are available to customize and save personal settings. In addition to automatic parameter adjustment, a manual panel with traditional two-knob operation is available with limited welding processes and functions.

Energy-efficient cooling

Dynamic gas and water cooling ensure optimal temperature control and power efficiency. Depending on the welding power level and duration, the power source’s cooling fans moderate airflow and the cooler motor’s run times between 15 seconds and 4 minutes, reducing electrical power consumption and localized noise levels.

Modular flexibility

The X5 FastMig’s wide range of accessories includes transport units, remote controls, and interconnection cables of various lengths. The 4-wheeled cart features a pivoting cylinder plate that allows safe cylinder loading at floor level without extra lifting.

Easy changing of wire spools

The ergonomically designed, top-loading wire feeder saves space and improves occupational safety in changing wire spools. It can also be hung up and adjusted to multiple different angles for easy accessibility, even in a dual setup. The handle’s internal structures are enforced to sustain temporary hanging in crane transfers.

Kemppi Connect

If you purchase Wise special processes or welding programs from Kemppi, you can install them with the help of a mobile application, Kemppi Connect. Kemppi Connect is available free of charge from Google Play. Login requires an active My Kemppi ID.

Ultimate welding comfort

Flexlite GX welding guns feature flexible cable sets and ball-jointed cable protection which reduce wrist loading. Their innovative neck structure adds to welding comfort with more efficient cooling, which also extends the lifetime of consumables. On-torch GXR10 remote control allows parameter adjustment at the weld joint.

Insight creates value

The X5 FastMig can be easily connected to the WeldEye cloud service, which offers automated processes for quality control, production analysis, and welding project management. The software also provides 100% traceability for each weld produced.

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

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.

SuperSnake GTX

SuperSnake GTX easily reaches the welding sites not accessible with the standard welding equipment.

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.
