Material & Engineering Design
Each XT series lead-free soldering tip starts with a high-purity copper core for maximum thermal conductivity. The tip receives a multi-layer plating system: a uniform iron layer for wear resistance (improving overall quality and durability), followed by chromium plating that prevents solder creep along the barrel, and an anti-oxidation layer that protects against corrosion during high-temperature lead-free soldering. Available lengths range from 37mm (for standard access) to 40mm (for extended reach), allowing you to match the tip to your specific repair or production environment. This combination of materials ensures consistent thermal transfer and long service life even under continuous lead-free soldering conditions.
Application Scenarios on Your Production Floor or Repair Bench
These XT tips are designed for versatile soldering applications using Weller stations:
Electronics repair and service centers (consumer electronics, mobile devices, gaming consoles)
Lead-free PCB assembly and rework (SAC305, Sn99.3Cu0.7 alloys)
Benchtop manual soldering using Weller WSD121 stations or WP120 soldering pencils
R&D labs and prototype assembly requiring repeatable lead-free soldering results
Technical training facilities needing durable, consistent tips for lead-free processes
The 37-40mm length options provide flexibility: shorter 37mm tips offer better control for fine-pitch work, while 40mm tips reach past tall components on dense boards. The chromium plating ensures the tip barrel remains free of solder creep – reducing cleaning downtime and extending tip life.
Product Value for Your Business (Cost, Consistency, Customization)
As a direct soldering tip manufacturer, we deliver three measurable advantages for your lead-free soldering operations:
Lower consumable cost: Factory-direct pricing eliminates branded markups. Typical savings of 30–50% compared to original Weller XT tips. For repair centers using dozens of tips monthly, this adds significant annual savings.
Batch-to-batch consistency: Every production lot uses identical copper purity, plating thickness, and dimensional tolerances. No unexpected thermal drift, poor wetting, or early tip failure – critical for lead-free processes where temperature accuracy matters.
Customization without proprietary constraints: Need a modified tip shape, a specific length outside the 37-40mm range, or a specialized plating for aggressive flux? We produce custom Weller soldering tips based on your drawings. Minimum order quantities apply.
For procurement and engineering teams, this means predictable quality, lower total cost of ownership, and a reliable second source for mission-critical consumables.
What materials and plating are used in these XT series soldering tips?
We use high-purity copper cores with a multi-layer system: iron plating (wear resistance, quality improvement), chromium plating (solder creep prevention), and an anti-oxidation layer (corrosion resistance). This combination is specifically engineered for lead-free soldering temperatures.
Do you offer custom XT tip shapes, lengths, or plating specifications?
Yes. As a custom soldering tip manufacturer, we can modify tip geometry (chisel, conical, bent, knife, hoof), total length (outside the 37-40mm range), or plating thickness for aggressive flux environments. 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 lengths available? Will these fit my Weller WSD121 or WP120?
Total length: available from 37mm to 40mm (specify when ordering). Our XT series lead-free soldering tip is compatible with Weller WSD121 stations and WP120 soldering pencils, as well as other Weller stations that accept standard XT series cartridges. Confirm your station's compatibility before ordering.
How does service life compare to original Weller XT tips, especially for lead-free soldering?
Under identical lead-free soldering conditions (350-380°C, continuous use with proper maintenance), our multi-layer plating delivers comparable or longer life – typically 12,000 to 20,000 solder joints depending on tip shape, solder alloy, and flux chemistry. The chromium plating also extends life by preventing tin creep. We recommend a side-by-side trial on your bench or production line to verify performance.
How should we maintain these tips for maximum life in lead-free soldering?
Keep the tip tinned when the iron is idle (use station sleep mode if available)
Clean with brass wire or a damp sponge – avoid abrasive files or tip cleaners
Lead-free solders require higher temperatures – use the lowest effective temperature for your application
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 high-volume repair centers, schedule weekly tip inspections
We supply detailed maintenance guides with bulk orders. For lead-free applications, proper tip tinning is especially critical – we recommend using high-quality lead-free solder wire with active flux.
