Pulse arc welding uses a brief, high-energy electrical discharge to fuse metal at a precise point, with minimal heat spreading to surrounding metal or stones. When used with an argon atmosphere, it leaves a clean surface with little to no oxidation, which makes it ideal for repairs near stones or on finished surfaces.

This session teaches the fundamentals of pulse arc welding and how it differs from traditional soldering and welding methods while exploring practical applications for common jewelry repair and manufacturing tasks. Attendees will discover techniques for achieving clean, durable welds on a variety of metals and best practices for equipment setup, operation, and maintenance.
