mismatched wire splices

Why this process

  • Handles mismatched cross-sections in one joint.
  • Energy and clamp force are set independently.
  • No solder to fill the size gap.
  • Low heat protects the thinner wire's insulation.

Typical applications

Mismatched harness splices · power-to-tail wire joints · repair splices · transition between cable gauges.

FAQs

Can different wire sizes be welded together?

Yes — that is the point of this configuration; energy and clamping force are tuned so the thick wire consolidates without crushing the thin one.

Why not just crimp?

A crimp on mismatched sizes often relies on the thick wire; a weld consolidates both into one metal mass.

Is a filler needed?

No — the metals are joined directly, with no filler to bridge the size difference.
