Material & Engineering Design
Each LHT automatic soldering tip is manufactured using high-purity copper that conducts heat quickly – ensuring rapid thermal response from the 150W heater to the solder joint. The tip then receives a specialized plating system: an iron layer for wear resistance, followed by double chrome plating for enhanced oxidation protection and uniform heat conduction across the working surface. The 11mm outer diameter provides sufficient thermal mass for high-power applications, while the compact 25mm total length allows the Weller robot to access tight spaces without compromising heat delivery. This combination of materials ensures corrosion resistance, uniform heat conduction, and long service life even under continuous 150W operation.
Application Scenarios on Your Automated Production Floor
These LHT tips are designed for Weller WSP150 automatic soldering robots (150W) used in:
High-thermal-demand PCB assembly (power electronics, automotive modules, battery management systems)
Soldering of large through-hole components (connectors, transformers, relays, thick cables)
Ground plane and multi-layer board soldering where standard 80W tips struggle
Industrial control and power supply production requiring high heat delivery
Contract manufacturing (EMS) running Weller robots for mixed high-mass and fine-pitch work
The 11mm diameter and 25mm length provide a compact profile that fits into dense assemblies while delivering 150W of heating power. The double chrome plating ensures the tip barrel remains oxidation-free – critical for automatic tip changers and consistent robotic positioning.
Product Value for Your Business (Cost, Consistency, Customization)
As a direct soldering tip manufacturer, we deliver three measurable advantages for your Weller robotic soldering lines:
Lower consumable cost: Factory-direct pricing eliminates branded markups. Typical savings of 30–50% compared to original Weller LHT tips. For 150W robots running high-thermal applications, tip wear can be faster – our competitive pricing reduces your annual consumable spend significantly.
Batch-to-batch consistency: Every production lot uses identical copper purity, double chrome plating thickness, and dimensional tolerances (±0.05mm). No unexpected thermal drift, uneven heat conduction, or early tip failure that disrupts automated soldering programs.
Customization without proprietary constraints: Need a modified tip shape for a specific high-mass component, a different length, or specialized plating for aggressive flux? We produce custom Weller automatic soldering tips based on your drawings. Minimum order quantities apply.
For procurement and automation engineering teams, this means predictable quality, lower total cost of ownership, a reliable second source for critical consumables, and the flexibility to optimize tip geometry for specific high-power applications.







What materials and plating are used in these LHT automatic soldering tips?
We use high-purity copper for rapid heat conduction, with an iron wear layer and double chrome plating that provides enhanced oxidation resistance, corrosion protection, and uniform heat distribution. This design is specifically engineered for 150W high-power automatic soldering.
Do you offer custom LHT tip shapes, lengths, or plating specifications?
Yes. As a custom soldering tip manufacturer, we can modify tip geometry (chisel, conical, knife, offset, gull-wing), total length (outside 25mm), outer diameter, or plating thickness for aggressive flux or higher-temperature applications. Provide a drawing, original sample, or intended application – our engineering team will advise. Custom orders require minimum quantity – contact our sales team.
What are the exact dimensions? Will these fit my Weller WSP150 robot?
Outer diameter: 11mm. Total length: 25mm. Our LHT automatic soldering tip is compatible with Weller WSP150 automatic soldering robots (150W) and other Weller stations that accept standard LHT series cartridges. Confirm your robot’s heater bore size before ordering. Contact us for compatibility verification.
How does service life compare to original Weller LHT tips in 150W applications?
Under identical high-power soldering conditions (380-400°C, continuous operation on ground planes, proper tinning cycles), our double chrome plated tips deliver comparable or longer life – typically 15,000 to 25,000 solder joints depending on tip shape, thermal load, and flux chemistry. The double chrome layer provides superior oxidation resistance. We recommend a side-by-side trial on your automated line to verify performance.
How should we maintain these tips on Weller WSP150 automatic soldering robots?
Program automatic tip tinning cycles during idle periods (e.g., every 30-60 minutes) – especially important for 150W high-power applications
Use automatic tip cleaners (brass wire or ceramic sponge) as part of your robot's routine
For high-thermal applications, use the lowest effective temperature to extend tip life
Replace immediately if the tip becomes pitted, deformed, or cannot wet properly
Store unused tips in a dry, anti-static container to prevent oxidation
For 24/7 operations with 150W robots, schedule weekly tip inspections and replace in sets to maintain consistent joint quality
The double chrome plating reduces oxidation, but periodic cleaning of the tip barrel is still recommended for automatic tip changer compatibility
We supply detailed maintenance guides and recommended robot parameters (including temperature offsets and tinning frequencies) with bulk orders. For high-volume EMS customers running Weller WSP150 robots, we also offer just-in-time delivery programs and custom packaging for automatic tip changers.
