Weller RTM 030 K ou RT7 2.2 mm Knife Soldering Iron Tip for use with WMRP, WXMP

This soldering iron tip is a knife-shaped replacement designed for precision thermal work in industrial environments. It fits compatible Weller handheld stations and is crafted to deliver angled-edge access for concentrated heat transfer during soldering and rework tasks. The tip’s configuration supports controlled solder application where an oblique approach and defined contact line are required.

• 45° tip angle provides controlled access for angled joints
• Knife-profile improves edge soldering and drag soldering performance
• 2.2mm width delivers focused heat for small-area contacts
• Compatible with designated handheld units for straightforward replacement
• Robust construction supports repeated thermal cycling during production

• Suitable for fine-edge soldering on component leads and traces
• Ideal for drag-soldering multiple pins in tight-pitch assemblies
• Used with handheld stations for electronic repair and rework
• Can be used for precision soldering tasks in automation setups
• Used for maintenance work in electrical and mechanical assemblies

The oblique 45° face lets technicians approach joints at an angle, improving visibility and enabling consistent wetting along an edge during linear soldering methods.

It is designed to be used with specific Weller handheld models that accept the corresponding tip shank and retention system.

The blade-like profile creates a narrow contact line, concentrating thermal energy for neat solder deposition on small or contiguous pads without excessive solder spread.

The 2.2mm contact width balances heat concentration and mass, allowing Rapid temperature recovery for brief solder cycles while limiting heat soak into surrounding components.
