Planning a custom resistance welding machine project? This guide provides a complete evaluation checklist covering workpiece materials, thickness, welding points, welding process, production cycle, electrode design, welding fixtures, power systems, automation, PLC control, safety protection, sample testing, equipment acceptance, maintenance, and after-sales service. Learn how to evaluate a customized spot welding machine before production, why actual workpiece sample testing is important, and how to determine whether standard or custom resistance welding equipment is suitable for your manufacturing process. PDKJ is a professional welding machine manufacturer providing medium frequency inverter spot welders, capacitor discharge spot welders, AC resistance welding equipment, and customized automated welding solutions.
Spot welding looks simple from the outside. Two electrodes press metal, a short current flows, and a strong joint appears. But the real process depends on heat, pressure, time, and control. In this article, you will learn how a spot welder works and how to choose a better setup.
Small metal joints can decide a product’s strength. A weak weld point can stop a whole line. This is why spot welding matters in modern manufacturing. In this article, you will learn what a spot welder is, how it works, where it is used, and how to choose the right machine.
Spot welding looks simple, but it is not basic. One small weld point can decide product strength, safety, and output quality. If you work with metal parts, spot welding may be one of the fastest ways to join them. In this article, you will learn how it works, where it fits, and how to choose the rig
Stainless steel looks strong, but it hates poor heat control. That is why many shops ask if spot welding can join it well. Yes, it can. In this article, you will learn when it works, what can go wrong, and how the right machine helps.
Can one small weld point hold a part firmly? Yes, if it is done right. Spot welding uses heat, pressure, and timing to join metal sheets. In this guide, you will learn how to prepare parts, set parameters, avoid defects, and choose a suitable machine.
Can aluminum be spot welded? Yes, but it is not forgiving. Aluminum moves heat fast and hides oxide on the surface. In spot welding, small setup changes can change the weld. In this guide, you will learn the right machine, settings, checks, and problems to avoid.

Learn the technology and working principle of spot welding machines, including welding current, resistance heat, electrode pressure, welding time, weld nugget formation, and cooling. This guide explains how spot welding works, the main types of spot welders, factors affecting weld quality, and how to select the right equipment for different materials, thicknesses, production volumes, and automation requirements. It also compares AC spot welding machines, medium frequency inverter spot welders, and capacitor discharge spot welders, while explaining why actual workpiece sample testing is important before equipment selection. PDKJ is a professional welding machine manufacturer offering resistance spot welding equipment, medium frequency inverter spot welders, capacitor discharge spot welders, and customized automated welding solutions.

Energy storage spot welder vs. medium frequency spot welder: learn the differences in working principles, welding characteristics, and application scenarios. This guide explains when to choose an energy storage spot welding machine for small metal components, thin materials, electronic parts, and precision welding applications, and when a medium frequency inverter spot welder is more suitable for high-volume production, multi-point welding, sheet metal fabrication, automotive components, new energy products, and automated welding lines. The article also explains how material, thickness, welding point quantity, production volume, welding cycle, weld strength, appearance requirements, and automation level affect equipment selection. PDKJ provides energy storage spot welders, medium frequency inverter spot welders, automated resistance welding systems, and customized welding solutions, with free welding process evaluation and sample testing to help manufacturers select the right equipment
Laser welding machine power is not simply a case of “the higher, the better.” This guide explains how to select the right laser welding power based on material, thickness, weld structure, welding speed, production cycle, and product quality requirements. Learn the three hidden drawbacks of blindly choosing an oversized laser welding machine, including higher equipment investment without proportional productivity gains, increased process-matching challenges, and potentially inefficient equipment utilization. The article also explains why insufficient laser power can create its own problems and provides practical guidance for selecting 1,000W, 1,500W, 2,000W, 3,000W, or higher-power laser welding equipment. PDKJ provides handheld, air-cooled, water-cooled, automated, and robotic laser welding solutions, along with free welding process evaluation and sample testing to help manufacturers select laser power based on actual workpieces and production requirements.
