How To Select The Right Chiller For Resistance Welding Applications
Sep 17, 2026| When choosing a resistance welding chiller, you need to focus on practical production conditions to guarantee stable electrode cooling and consistent weld quality.
1. Required cooling capacity
Calculate the heat load generated by electrodes during continuous spot‑welding cycles. Insufficient cooling leads to rapid electrode deformation.
2. Temperature stability
Steady water temperature avoids welding spatter, discoloration and unstable nugget formation.
3. Water flow and pressure
Match flow rate and pressure to the welding gun and electrode water‑passage structure.
4. Anti‑scaling & water quality protection
Long‑time industrial operation easily causes internal scale, which blocks narrow electrode cooling channels.
5. 24‑hour continuous‑running performance
Mass automotive or metal component production requires chillers capable of non‑stop operation.
6. Local voltage and certification
Confirm site power supply and required compliance documents such as CE certificates.
