Katool KT-90E Body Spot Welding Machine

This stud welder and dent puller is built around a stainless steel body with pure copper wire windings — a construction choice that directly affects heat management and weld consistency over a long workday. It ships with two welding guns, one configured for pulling and one for welding, so you're not swapping attachments between functions mid-job. Seven selectable welding modes with adjustable power levels cover a range of panel thicknesses and repair types, with settings displayed on a digital panel that also lets you toggle between automatic and manual operation.

The cooling design skips the fan and instead uses passive ventilation through side ports combined with automatic overheating protection — the system cuts out before thermal damage occurs rather than relying on a fan that can clog or fail. The single-sided welding thickness of 0.6 + 1.2mm produces small, controlled weld spots with enough strength to pull effectively, without burning through to the back coating or damaging the paint surface on the reverse side. That's a meaningful spec when you're working on visible panels where collateral damage creates more work. A full accessory kit is stored in an included toolbox, covering the common range of dent and deformation repairs without sourcing additional tools separately. The compact body and integrated handle make it portable between bays or to a job site.

A practical fit for auto body shops handling daily dent and collision repair, mobile dent repair technicians who need a self-contained kit that travels, and detailing or PDR operations expanding into welded dent pulling for damage that goes beyond what paintless repair can address.

Features

• Minimal Welding Traces: Features a single-sided welding thickness of 0.6+1.2mm, producing small, clean weld spots with strong adhesion — all without damaging the back metal coating or paint surface.
• Dual Welding Guns: Comes equipped with two welding guns that switch seamlessly between pulling and welding functions, eliminating the need to swap guns and significantly improving workflow efficiency.
• Efficient Fanless Cooling System: Side ventilation holes provide rapid heat dissipation without the need for a fan, reducing the risk of overheating during extended use. An automatic overheating protection function adds an extra layer of safety.
• 7 Selectable Welding Modes: Offers 7 welding modes with multiple adjustable power levels, all clearly displayed on a digital panel. Easily switch between automatic and manual operation at any time for a fast, straightforward experience.
• Complete Accessory Kit Included: Comes with a full set of accessories neatly organized in a toolbox, covering all common dent repair needs across multiple welding modes. The compact, lightweight body and built-in handle make it easy to carry and use on the go.
