Turn on the heat with HotSpot

Turn on the heat with HotSpot

Perfect for vehicle repair and thin sheet fabrication environments, the HotSpot™ function with four different heat settings makes metal shrinking and component heating simple and convenient. Simply fit the carbon electrode set to the FE welding gun and activate HotSpot™ on the control panel. An electrical circuit is formed once the carbon electrode touches the work piece, which gently heats the metal’s surface. HotSpot™ can also be used to heat and help release corroded nuts and bolts and other metal components.

The making of 'Laulupuut' welded sculpture

A 13-meter high giant pike singing with its mouth wide open now occupies a prime location at the square in front of the Helsinki Music Centre in Helsinki, Finland. The Laulupuut ('Song Trees') artwork, designed by sculptor Reijo Hukkanen, also extends around the pike. The sculpture made of aluminum and steel has proven exceptionally popular. However, both its makers and Hukkanen himself let out a sigh of relief when it was erected in August 2012.

How Rapid Welding and Kemppi Built a Partnership That Lasts

How Rapid Welding and Kemppi Built a Partnership That Lasts

Rapid Welding has worked with Kemppi since the company opened in 1990. Co-founder and Managing Director Roy Edwards highlighted the principles behind that 36-year partnership, from choosing the right welding solution and supporting equipment throughout its life to addressing the skills shortage and finding the right place for automation and laser welding.

Safety that keeps up with welders' challenges and changing risks

Safety that keeps up with welders' challenges and changing risks

Welding safety has become increasingly demanding. The hazards at the arc remain constant, but modern working conditions mean exposure can accumulate over longer shifts and in tighter indoor spaces. As a result, welding PPE needs to be treated as both protection for the welder and proof of compliance. At Kemppi, welding safety PPE is designed and validated in practice through clear requirements, welder-led feedback, and verified compliance with EU PPE Regulation 2016/425, CE marking processes, and relevant EN standards.
