Basic Standard Profile

Full Title: Resistance welding equipment — Electrode adaptors, male taper 1:10 — Part 1: Conical fixing, taper 1:10

Edition: 3rd edition, published 12-Feb-2026, superseding ISO 5183-1:1998

Technical Committee: ISO/TC 44/SC 6 (Resistance Welding Subcommittee)

ICS Code: 25.160.30 (Welding equipment)

Standard Positioning: Core segment of the ISO 5183 series, establishing unified specifications for 1:10 male taper electrode adaptors applied in resistance spot welding scenarios

ISO 5183-1:2026 defines the standardized dimensions and tolerances for resistance welding equipment, specifically electrode adaptors with a male taper of 1:10. This standard focuses on conical fixing where the electrode adaptor's male taper is used to attach spot welding electrode caps. The adaptors align with the requirements of ISO 5821 for cap compatibility and ISO 1089 for electrode taper fits. It provides guidance for manufacturers and users of resistance spot welding equipment, ensuring global compatibility and interchangeability in the resistance welding industry.
