Weller Soldering Iron Tip, 22mm Tip Length, 0.4mm Tip Width - T0054442699

This soldering iron tip is designed for precision soldering tasks with compatible Weller stations. It functions as a replacement tip for recent-generation handheld soldering tools and is intended for fine work that requires a narrow contact point and a controlled angle of approach.

Features and Benefits:

• Bent conical geometry enables access to confined joints
• 0.4mm tip width delivers fine solder deposition
• 30° angle aids consistent contact alignment
• Long-life LT construction reduces frequency of changeouts
• UPC approval confirms standardised manufacturing compliance

Applications

• Suitable for reworking miniature through-hole components
• Used with WP80 series for electronics assembly tasks
• Ideal for precision touch-up on small SMD pads
• Used with LR21 and TCPS tool variants for repairs
• Can be used for detailed connector soldering in tight spaces

Which handpieces will accept this tip?

It fits last-generation LR21 and TCPS handpieces as well as WSFP, WSP80, WP80 and WXP80 soldering tools.

How does the tip shape affect thermal transfer?

The bent conical form concentrates heat at the narrow point, improving thermal delivery for small joints while limiting heat spread to surrounding areas.

What practical advantage does the 30° angle provide?

The angled profile permits a natural approach to confined or angled pads, improving visibility and making steady contact easier during soldering.

Is this tip intended for high-volume replacement cycles?

The LT design targets extended service life, reducing the rate of replacements compared with standard general-purpose tips.
