Weller RTMS 004 S MS 0.4 mm Chisel Soldering Iron Tip for use with WXMPS-MS (Smart) Soldering Iron

This soldering iron tip is a precision chisel accessory intended for use with compatible smart Weller handpieces in electronics and industrial settings. It serves as a replaceable contact point for heat transfer during soldering tasks, offering fine control for delicate assembly and repair work in automation, electrical and mechanical environments.

• Chisel profile provides controlled solder flow for neat joints
• 0.4mm width enables fine-feature soldering on small components
• Designed for smart iron compatibility for straightforward replacement
• Robust tip material supports repeat thermal cycles during production
• Slim geometry improves access to densely populated boards

• Suitable for component-level soldering on Compact assemblies
• Ideal for rework of surface-mount devices in electronics manufacturing
• Used with smart WXMPS-MS tools in automated repair stations
• Can be used for precision wiring and connector tasks in electrical work

The connection Interface matches the smart iron’s mounting system to allow direct substitution without adaptors.

The flat cutting edge concentrates heat and solder, facilitating efficient wetting on narrow pads and shorting-prone areas.

The construction tolerates frequent thermal cycling typical in production and service environments, maintaining shape and transfer characteristics.

Fine-pitch soldering, precise touch-ups and working around fine leads all gain improved accuracy from the narrow tip.
