Weller MTG40 Chisel Soldering Iron Tip 0.625 in SP175

Product Description

The WELLER MTG40 is a chisel-style soldering iron tip from the MTG series, designed for use with the Weller SP175 soldering iron. It features a 0.625 inch tip point width and a 0.625 inch tip diameter, making it well suited for general-purpose soldering work on larger pads, through-hole components, and wiring terminations. The tip measures 2.375 inches in length and weighs under 1 pound, keeping the iron well balanced during extended use. Electricians, electronics technicians, and industrial maintenance personnel will find this tip practical for jobs that demand broader heat transfer and consistent contact across wide solder joints.

The MTG40 is appropriate for residential and commercial electrical work, panel wiring, connector soldering, and bench-level electronics repair. Its chisel geometry delivers flat, broad contact with the work surface, which improves heat conduction to larger joint masses compared to a conical or pencil tip. Technicians working with heavier gauge wire terminations, bus bars, or large-footprint through-hole leads will benefit from the wider contact area this tip provides.

Key Features

• Chisel tip geometry for broad, efficient heat transfer to larger solder joints
• 0.625 inch tip point width for wide-contact soldering applications
• 0.625 inch tip diameter matched to SP175 iron barrel dimensions
• 2.375 inch tip length for reach into confined work areas
• Part of the MTG series, designed as a direct-fit accessory tip

Compatibility

The MTG40 is designed for use with the Weller SP175 soldering iron as specified by the manufacturer.

Installation Notes

Tip replacement should be performed with the soldering iron fully powered off and cooled to ambient temperature before handling. Use the appropriate tip removal tool or heat-resistant pliers if the tip is seated tightly — avoid gripping with bare hands. Inspect the tip seat and barrel threads for oxidation or debris before installing the new tip. Follow applicable workplace safety guidelines and local electrical codes when using soldering equipment in trade settings.
