Our CDB-2500/3500 handheld stud welder replaces tedious welding work with a rate of over 40 studs per minute, low-heat welds that avoid sheet burn-through or deformation, while leaving no backside marks to preserve material appearance. Compatible with M3-M10 studs and materials like stainless steel, steel, and aluminum, they auto-adjust voltage according to your specifications, making it easy to use even for beginners, and come factory-direct for fast delivery plus labor savings from zero post-weld finishing.

As the core component connecting the handheld laser welding torch and the workpiece, our copper nozzle tip achieves the core welding needs of precise light control, efficient gas guidance and stable wire feeding in terms of function. Combined with the anti-adhesion and gun protection design and 3-second quick-release structure, it not only greatly improves welding precision and operation efficiency, but also effectively reduces slag adhesion and equipment maintenance costs. In terms of materials, a variety of options including CuCrZr, pure copper, coated modified copper and oxygen-free copper are provided, which are respectively suitable for different scenarios such as industrial mass continuous welding, small-batch fine welding, high-reflection material/precision electronic welding and micro-welding, fully meeting the process requirements of various laser welding applications.
Your questions about our handheld capacitor discharge stud welder, answered by our experts.
Capacitor discharge stud welders use low, concentrated heat, right for thin sheets, fast, and low spatter. Arc stud welders use higher, longer heat — better for thick sheets, but may warp thin materials.
First, we know that aluminum welding often has these problems:
High thermal conductivity:
