Tweco Contact Tips – #5 1.0mm Contact Tip (15H40), 1.2mm Contact Tip (15H45), 1.4mm Contact Tip (15H52) and 1.6mm Contact Tip (15H116)

R26,91

Performance & Compatibility

Compatible with Tweco #5 / Weldskill / Spray Master MIG guns. Ensure proper diffuser and nozzle fit.
Rated for heavy duty welding up to ~500 amps (depending on wire size / duty cycle).
Best used with matching wire size; using too large tip bore with thin wire causes poor arc control, spatter; too small bore causes wire burn‑back, feeding issues.
Regular inspection & cleaning will prolong tip life; rotated tips (if design allows) may extend service.

Ordering & Packaging

Supplied in packs of 25 pieces per size for most standard types.
Each tip stamped / marked with part number and wire size.
Typical part numbers might be 15H‑40, 15H‑45, 15H‑52, 15H‑116 (or equivalent equivalent codes in other brands).

Description

Tweco / Weldskill 15H Series #5 MIG Contact Tips

Product Description

Heavy‑duty, performance contact tips for #5 Tweco welding torches. Designed for high amp MIG applications (up to ~500 A), these contact tips are precision made to ensure excellent wire feed, stable arcs, long life, and reliable conductivity. Each tip is clearly marked with its wire size and part number for quick identification.

Key Features

Made from 122 DHP copper alloy for high electrical conductivity and heat dissipation.
Machined or gun‑drilled bore with smooth inside surface to reduce friction, wire burn back, and improve feed consistency.
Tight internal diameter tolerance (± 0.003 in) ensures good fit for wire size and reduced arc instability.
Standard #5 Tweco (Weldskill / Spray‑Master) thread: 5/16‑18 UNC‑2A. Ensures proper mating with diffusers / gas cups.
Overall length ~1.97 in (≈ 50 mm) to suit standard #5 torch geometry.
Marked with wire diameter / part number for fast identification during maintenance or swaps.
