Soldering Iron Tip copper for pencil soldering iron LG-400/500, compatible, MPN 67400 GROT

Copper soldering iron tip designed for pencil-style soldering irons compatible with LG-400 and LG-500 models. This replaceable copper tip provides a direct heating surface for efficient heat transfer and reliable solder wetting on small components and wiring. It is intended for use where a removable copper contact surface is preferred for repair, maintenance, and hobby electronics tasks; check physical fit with your iron before purchase.

Advantages

The copper construction ensures good thermal conductivity and fast heat transfer to the solder joint, improving soldering speed on small pads and leads. The tip is shaped for precise solder application, and compatibility with pencil-style irons allows easy replacement without specialized tools. Its removable design reduces wear on the main iron element and simplifies maintenance.

Suitable for

• General electronics soldering and assembly
• Component replacement and circuit board repair
• Hobbyist PCB work and prototyping
• Fine wiring, connectors and small lead soldering

Key specifications

• Material: copper contact surface
• Type: pencil-style replacement tip
• Mounting: replaceable tip compatible with LG-400 / LG-500 form factor
• Application temperature range: suitable for typical soldering temperatures for electronic components
• Intended use: hand soldering of small components and wires

How to use

Allow the soldering iron to reach the appropriate working temperature for the solder alloy used. Insert or secure the copper tip into the pencil-style iron following the iron manufacturer’s alignment and fastening method. Clean the tip with a damp sponge or brass wool before tinning to ensure good thermal contact. Apply solder to the joint while maintaining steady thermal contact between the tip, component lead and pad; avoid excessive pressure that could damage pads or traces. After use, tin the tip lightly to protect the copper surface and prevent oxidation.

Usage recommendations

Use flux and the correct solder alloy for the components being worked on; avoid prolonged heating of sensitive components. Replace the tip when significant erosion or deformation reduces solder transfer efficiency.
