E1C Fine Wire Resistance Welder for Copper & Aluminum Micro-Diameter Wire
The E1C Fine Wire Welder is built for precision solid wire joining in copper and aluminum. Designed for continuous operation, it handles the small diameters and tight tolerances of fine wire production with a 10-point heat selection switch for controlled, repeatable heat input and a spring-loaded upset mechanism for consistent pressure during the weld. Spring-loaded clamp fingers help maintain proper alignment, while the mounted lamp and squaring shear support wire preparation and welding at one compact station. Operating on 110V single phase, the E1C is a straightforward, dependable solution for fine copper and aluminum wire applications.

Applications
Keeping fine wire drawing lines running by splicing solid copper and aluminum wire at diameters from .015 to .050 inch without scrapping coils
Resistance welding magnet wire and winding wire at micro-diameters where silver solder brazing would introduce inconsistent joint geometry
Maintaining continuity in precision winding operations — motors, transformers, inductors — where a wire break mid-coil means a scrapped assembly
Splicing aluminum fine wire ahead of drawing or respooling in operations where the BU series’ copper-only range falls short
Supporting electronics, sensor, and specialty wire fabrication where clean, low-profile resistance welds at sub-.050 inch diameter are a process requirement
Real-World Benefits
- At .015 inch minimum diameter, the E1C is purpose-built for micro-diameter wire that demands precise gripping and alignment.
- Resistance welding rather than brazing produces a fusion joint with no added filler material — a clean, low-profile joint for fine wire operations.
- Spring-loaded clamp fingers hold micro-diameter wire ends in precise alignment before the weld fires — the kind of mechanical repeatability that matters when wire is too thin to re-grip and retry.
- Ten-position tap heat selection gives operators a straightforward, stable heat setting for each wire size and alloy, without the fine-tuning overhead of a continuous Variac on a high-volume fine wire line.
- No air supply required — the E1C runs on 110V single phase and is available in bench mount or 4-wheel truck configurations, making it deployable in drawing rooms, winding cells, or lab environments without utility modifications.
Comparison to Similar Models
The E1C sits at the fine end of Micro Weld’s range — below the BU-1 in wire diameter and distinct from it in process. Where the BU-1 uses silver solder brazing for fine copper conductor, the E1C performs resistance butt welding on solid copper and aluminum wire from .015 to .050 inch, with no filler material. For operations requiring brazing of slightly heavier fine-gauge copper, the BU-1 covers solid copper from 28 to 16 AWG and stranded copper from 26 to 16 AWG. Step up to the AD Series when your application moves beyond solid rod into stranded conductor or larger cross-sections.
Best For
Fine wire drawing operations, magnet wire producers, and precision winding facilities working with solid copper and aluminum wire at .015 to .050 inch diameter — applications where resistance welding at micro-scale is required and filler-based brazing isn’t an option.
