Product Description – LT Series Soldering Tips for Weller Stations
Precision Tips for Weller WSD81/WSD121 & WP80 Handpieces
Engineered for Weller WSD81 and WSD121 soldering stations, these LT series tips are also fully compatible with WP80, WSP80, and WXP80 soldering irons. Designed for professionals in electronics repair, PCB assembly, and production environments, they deliver consistent heat transfer and reliable performance for fine soldering applications.
Material & Plating
Each tip features a C1100 copper core (copper content ≥ 99.90%) with thermal conductivity of approximately 380–400 W/(m·K). Formed by cold heading, the core offers about 15% higher thermal conductivity than machined alternatives, ensuring rapid heat delivery to the joint.
The 96-hour nano-composite electroplating process applies four functional layers:
Iron layer (12 A/dm²): Dense crystalline structure for superior corrosion and wear resistance
Nickel layer (8 μm): Prevents rust and protects the copper base
Hard chromium layer (18 A/dm²): Maximizes oxidation resistance and prevents solder creep
Tin layer (12 μm): Pre-applied to the working end for immediate wettability
Performance & Compatibility
Long Service Life: Delivers 20,000–38,000 solder joints under standard conditions (350–400°C, proper maintenance). Actual lifespan depends on temperature, flux, and solder alloy.
Cost-Effective: Offers 30–50% savings compared to genuine Weller LT tips, with consistent quality across all batches.
Precision Fit: Diameter 6.0 mm, total length approx. 13–18 mm (varies by tip shape) – ensures secure contact with Weller handpieces.
Applications
Suitable for PCB repair, fine soldering of small components, prototyping, and light production environments. Compatible with both lead-free (SAC305) and leaded (Sn63Pb37) soldering processes.
Maintenance & Replacement
To extend tip life:
Clean with a damp sponge or brass wire ball during use.
Apply a solder "tin cap" before powering off.
Use recommended temperatures: 350°C ± 10°C for lead-free, 320°C ± 10°C for leaded solder.
Never use files or abrasives – these damage the plating.
Replace immediately if you observe:
Pits or holes on the working surface
Solder creeping up the barrel
Significant loss of heating efficiency
Permanent blackening that rejects solder
