Kemppi's advanced welding processes: TIG and stick welding (MMA)

In TIG welding, process development has mainly focused on modifying the current modes in different situations. In practice, this means variations of pulse and AC welding, as well as ignition or tack welding. In the case of pulse welding, the welding machine user has numerous choices, as the adjustment possibilities for these process variations are highly versatile.

Introducing the X3 FastMig

MIG Welding Highlight

Complete high-quality welds in any work environment. With easy-to-use controls and a durable design, the X3 FastMig is a brilliantly simple MIG/MAG welder that is perfect for heavy industrial welding. With 420–450 amps of power at a 60% duty cycle, the X3 is brutally effective without compromising quality. It's extremely powerful, but it's also precise enough for welds that just need to be done quickly.

Some metals, like aluminum, have a naturally occurring, tough surface oxide layer. That surface oxide layer must be removed to enable successful welding. In the case of aluminum alloys, the surface oxide layer has a significantly higher melting temperature (approximately 2000°C) than the melting temperature of the aluminum base material (660°C).

Making weld cleaning easy and cost-efficient

Blog

Welding is all around us. It binds together the metals to build structures essential to our everyday lives. However, beyond the visible sparks and strong connections, there's an aspect often underestimated: weld cleaning. Especially with stainless steels, proper weld cleaning not only improves the aesthetic appearance of the weld but also ensures its strength, durability, and overall quality.

High five to X5 ✋ for special processes ​

No two welding jobs are the same. That is why X5 FastMig masters every material and weld 🔥. Combined with Kemppi’s advanced processes, it delivers perfect results from stainless steel and aluminum to thick structures and thin sheets.​

Five technical reasons to give a high five to X5 & special processes:​

1️⃣ WiseRoot+ for root passes​
Achieve TIG-quality welds at MAG speed, with profitable filler material and shielding gas. Recommended: 1.2 mm solid wire with 100 % CO₂, up to 180 A. Spatter-free, high-speed, and maximized productivity.​

2️⃣ WiseSteel for structural steel​
Adaptive arc control ensures stable high-speed welding across all plate thicknesses. Example: 5 mm fillet weld with 3 mm throat thickness welded over 1000 mm/min.​

3️⃣ WiseFusion for deep penetration​
Adaptive control maintains a short arc in all conditions. Enables low heat input while maintaining excellent weld quality.​

4️⃣ MAX Position for position welding​
Challenging positions no longer require flux-cored wire. MAX Position allows the use of solid wire, ensuring easy pool control and faster travel speeds.​

5️⃣ WiseThin+ for thin sheets and MIG brazing​
Ideal for <2 mm steel and stainless steel, CuSi or CuAl brazing. Reduces heat input, minimizes distortion, and produces smooth, spatter-free welds.​

Give a high five in the comments if one of these processes could improve your work!
