The KDH Series Welder Welding Machine Switch is specially designed for welding equipment.
With multi-pole cam rotary design, the switch delivers smooth rotation, clear gear positioning and highly accurate parameter conversion. Compact structure and standard mounting design make installation quick and easy, perfectly matching portable welders, industrial arc welders and inverter welding machines.
Compared with ordinary switches, KDH welding machine switch has stronger anti-arc and anti-aging performance, greatly reducing equipment failure rate and after-sales problems. It provides stable welding effect, safer operation and longer service life, bringing reliable and worry-free user experience.
As a direct factory, we provide strictly inspected products, competitive factory prices and complete after-sales technical support, making us the trustworthy partner for global welding machine manufacturers.
Adopting multi-pole cam rotary technology, the KDH Welding Machine Switch achieves precise mechanical positioning and synchronous circuit conversion. The optimized stacked layered structure enhances overall compression resistance, insulation strength and arc ablation resistance. The internal mechanical transmission structure is precisely calibrated, ensuring smooth rotation, clear gear feel. The panel mounted design greatly simplifies installation and perfectly fits the internal limited space of various welding machines.
Static contacts: H62 brass Moving contacts: Phosphor bronze
H62 brass for static contacts offers great rigidity, high structural strength and outstanding corrosion resistance. It keeps stable shape under repeated current impact and high temperature, preventing terminal deformation. Phosphor bronze adopted for moving contacts has excellent elasticity, high wear resistance and anti-fatigue performance. It maintains consistent contact pressure after frequent switching, ensures tight contact and avoids poor connection or arcing. The combination of H62 brass static contacts and phosphor bronze moving contacts reduces contact resistance, minimizes heat generation during operation and extends the overall service life of the Welding Machine Switch.
Our KDH Series Welding Machine Switch is available in multiple current specifications: 25A, 40A and 63A for your selection.
The 25A model suits small portable welders for light-duty welding tasks.
The 40A version is widely used for medium-sized welding machines for regular workshop production.
The 63A heavy-duty model is designed for industrial high-current welders that run long continuous working hours.
Different current ratings help customers pick the proper Welding Machine Switch according to their welder’s maximum working current. All rated versions adopt H62 brass static contacts and phosphor bronze moving contacts, ensuring low contact resistance and stable conductivity under corresponding load conditions. As a professional manufacturer and supplier from China, our factory supports customized solutions for special current requirements.
