The Complete Professional Battery Welding System — Dual Pulse Precision, Pneumatic Consistency, and Production-Ready Control in One Bundle This is the battery welding setup that se rious manufacturers use. The Sunstone CDDP-A advanced dual pulse CD welder, WH2 pneumatic parallel weld head, and GlidCop battery electrodes are combined here as a complete, pre-matched system — recommended by Sunstone's own team as the right configuration for production-level battery pack assembly. Why This Bundle Exists Moving from a handheld probe and single pulse welder to a fully integrated weld head system is one of the most meaningful upgrades a battery manufacturer can make. But knowing exactly which three components to buy — and confirming they're matched correctly to each other — takes expertise most buyers don't have at the point of purchase. This bundle solves that. Every component is specified, matched, and recommended by Sunstone for production battery welding. You're not assembling a system from individual parts and hoping they work together. You're buying a system that has already been validated for this exact application. What's in This Bundle 1. Sunstone CDDP-A — Advanced Dual Pulse CD Spot Welder The CDDP-A is the most advanced capacitive discharge welder in Sunstone's lineup and the power supply at the center of this system. It stores energy in capacitors and releases it in two precisely timed pulses per weld cycle — a conditioning pulse that cleans the surface and seats the electrodes, followed by the full weld pulse that makes the bond. The result is cleaner, stronger, more consistent welds than a single pulse welder can achieve on the same material — particularly on sensitive cell chemistries and higher-demand applications where surface consistency varies. What sets the CDDP-A apart from any other power supply in this class: Full capacitive touchscreen interface — all parameters set and monitored from a single screen, with a real-time weld waveform display Weld monitoring with alarms — current, voltage, and power monitoring with user-defined limits. The machine flags or stops when a weld falls outside spec, catching weak welds before they leave the line Statistical process controls (SPC) and histogram — production-grade quality tools built into the machine, not bolted on as an afterthought Full weld head control — when paired with the WH2 pneumatic head (included in this bundle), the CDDP-A takes over squeeze timing, weld trigger, and post-weld hold as a single integrated cycle PLC ready — connects to robotic systems, automated indexing tables, and production line controllers for full automation integration Welder cloning — copy all settings from one unit to another in seconds, essential for multi-machine production lines Wi-Fi connectivity and data export — pull weld data out of the machine for external analysis and quality documentation Available in 200 Ws, 400 Ws, 600 Ws, and 1200 Ws power configurations 2. Sunstone WH2 Pneumatic Parallel Weld Head The WH2 replaces the handheld dual probe with a bench-mounted, pneumatically actuated weld head that delivers the same electrode force on every single weld — regardless of operator, fatigue, or technique. This is the mechanical foundation of a consistent production process. Both electrodes contact the top surface of the nickel tab simultaneously, making two parallel weld spots per actuation without any access to the underside of the cell. The WH2's built-in pressure regulator works with any standard shop compressor. Electrode pressure is adjustable from 1 to 15 lbs, head travel range is 0 to 7.25 inches, and the system is triggered by the included foot pedal — or managed entirely by the CDDP-A's integrated timing control. When the WH2 is connected to the CDDP-A, the entire weld cycle — electrode descent, weld trigger, post-weld hold, and release — runs from a single foot pedal press. The operator positions the part; the system handles the rest. 3. GlidCop Battery Welding Electrodes (1 Pair) GlidCop is a copper alloy engineered for welding electrode applications. Compared to standard copper electrodes, GlidCop runs cooler, maintains its shape longer under repeated use, and resists the mushrooming and degradation that shortens standard electrode life in production environments. These are battery-style electrodes with stepped tips designed specifically for tab-to-cell contact geometry — not general-purpose copper probes. Included in this bundle in the correct diameter to match the WH2 weld head variant you select. Who This Bundle Is Built For This is a production system, not a starter kit. It's the right bundle if you are: Running battery pack assembly at production scale — consistent shift-length output with documented, monitored weld quality Working with more sensitive cell chemistries — LiFePO₄, NMC, high-drain cells, or any application where heat sensitivity or surface consistency demands dual pulse conditioning Scaling from R&D into manufacturing — you've validated your pack design and are now building to repeatable, traceable production standards Operating in a quality-controlled environment — where weld data, SPC tools, and pass/fail monitoring are part of your process documentation Running multiple machines in parallel — welder cloning and data export make multi-unit consistency manageable Planning for future automation — the CDDP-A's PLC readiness means this system can grow into a robotic or automated production line without replacing the power supply If you're still in the prototyping or low-volume phase, our [Entry-Level Battery Welding Bundle] (CDSP + DPHP) is the right starting point. This bundle is the step you take when you're ready to operate at a professional level. Choosing Your Configuration This bundle is configurable across two variables: CDDP-A power level and WH2 weld head actuation type. The electrodes included are matched to the weld head variant you select. CDDP-A Power Level All four power variants share the same touchscreen interface, dual pulse technology, weld monitoring, SPC tools, and PLC integration. The difference is maximum stored energy — which determines what materials and thicknesses you can weld. 200 Ws — fine nickel strip (0.1–0.15mm), thin tab materials, lighter duty production. The right entry point into the CDDP-A platform if your tab stock is on the thinner end. 400 Ws — the most popular choice for production battery pack assembly. Handles a wide range of tab thicknesses and cell configurations, with meaningful headroom above the 200 Ws for material variation across a production run. 600 Ws — for thicker tabs, heavier nickel strip, copper tab materials, or high-duty-cycle lines where the 400 Ws is near its ceiling. If you're welding copper or running demanding production schedules, this is where you want to be. 1200 Ws — maximum power for the most demanding applications: thick, highly conductive, or highly resistive materials, and industrial/defense-grade production environments. When in doubt between two power levels, choose the higher one. You can always dial back energy on a more powerful machine; you cannot exceed the ceiling of an underpowered one. WH2 Weld Head Actuation Pneumatic (WH2125A) — air-actuated, consistent electrode force on every weld, integrates fully with the CDDP-A's timing control for single-pedal operation. Requires a standard shop air compressor. Recommended for production environments. Manual (WH2125M) — foot pedal actuated, no air supply required, operator controls electrode descent speed and pressure. Better suited to lab, R&D, or lower-volume work where compressed air isn't available. The electrodes included in this bundle are matched to the 1/8" electrode holder on both WH2 variants (WH2125A and WH2125M). If you require 1/4" electrodes for a WH2250 head, contact our team before ordering. Why Buy This Bundle From The Maker's Chest?

Frequently Asked Questions How is this different from the Battery Starter Kit (CDSP + DPHP)? The Starter Kit is the right starting point — a single pulse welder and a handheld probe, ideal for prototyping, R&D, and lower-volume battery pack work. This bundle is the professional upgrade: a dual pulse welder with weld monitoring and process control, a pneumatic weld head that eliminates operator-dependent pressure variation, and production-grade GlidCop electrodes. The step up is in consistency, traceability, and production readiness — not just power. Why does dual pulse matter for battery welding specifically? Battery cell terminals and nickel tabs aren't always perfectly clean. Micro-oxides, handling residues, and surface inconsistencies are common in real production conditions. The conditioning pulse burns off those contaminants and seats the electrodes before the weld pulse fires — producing a stronger, more consistent bond than a single pulse on the same surface. For sensitive cell chemistries or higher-demand applications, this difference is meaningful. What does the weld monitoring system actually catch? The CDDP-A monitors peak current, voltage, and power on every weld and compares the result against your defined acceptable range. A weld that's too weak — due to poor electrode contact, a contaminated surface, or electrode wear — will show up as an out-of-spec current reading before you ever see a physical failure. The machine can stop and alarm, or flag the weld and continue, depending on how you configure it. In production battery welding, this is what prevents bad cells from making it into finished packs. Does the CDDP-A control the WH2 weld head directly? Yes — when the WH2 pneumatic head is connected to the CDDP-A, the welder takes control of the squeeze timing, weld trigger, and post-weld hold. The operator positions the part under the electrodes and presses a single foot pedal. The CDDP-A drives the head down, holds the set pressure, fires the weld at the programmed timing, and releases — all in one automated cycle. This eliminates manual timing variation and is one of the most significant consistency improvements in moving from a handheld setup to a weld head system. Do I need a specific air compressor for the WH2 pneumatic head? No. The WH2 comes with a built-in pressure regulator, so any standard shop compressor works. You set the desired electrode force at the regulator and the head delivers it consistently on every actuation. Are the electrodes in this bundle consumable? How often do they need replacing? Yes — all welding electrodes are consumable. GlidCop electrodes last significantly longer than standard copper electrodes because the alloy resists mushrooming and maintains tip geometry under repeated high-current use. Replacement frequency depends on your weld energy, duty cycle, and tab material. Your weld monitoring data will show you when electrode wear is affecting weld quality — current readings will start trending out of your acceptable range as tips degrade. Can this system integrate with a CNC table or robotic arm? The CDDP-A is PLC ready with multiple communication protocols supported, making it compatible with CNC tables, robotic positioning systems, and automated production line controllers. If you're planning a fully automated setup, contact our team to discuss integration requirements before purchasing. What is your return policy? 75-day returns. If the system doesn't perform as expected in your production environment, reach out and we'll take care of you.
