P4-15T - Tweco #4 Style 400 Amp MIG Gun, 15 ft

Reliable 400 Amp MIG Welding Gun

The Techniweld P4-15T MIG Gun is a heavy-duty, air-cooled torch designed for professional welders who demand reliability and performance. Modeled after the industry-standard Tweco #4 design, this gun is rated for 400 Amps, making it an excellent choice for structural steel fabrication, heavy equipment repair, and general industrial manufacturing. With a 15-foot cable, it provides the necessary reach to move around large weldments without constantly repositioning your wire feeder.

Compatibility and Convenience

One of the biggest advantages of the P4-15T is its compatibility. It features a standard Tweco #4 rear connection (power pin), allowing it to plug directly into a wide range of wire feeders from major brands that utilize this connection style. Furthermore, it uses standard Tweco-style consumables, including 14-series contact tips, 24-series nozzles, and 54-series gas diffusers. This means you can easily find replacement parts at Josef Gas or almost anywhere welding supplies are sold, minimizing downtime.

Built for the Shop Floor

Durability is key in industrial environments. The P4-15T features a rugged outer jacket that resists abrasion, cuts, and burns from hot sparks. The handle is ergonomically designed to fit comfortably in the hand, reducing grip fatigue during extended welding sessions. Heavy-duty spring strain reliefs at both the handle and the feeder end protect the internal copper cabling and liner from kinking or breaking, ensuring a long service life and consistent wire feeding performance.

Key Features

• High Output: 400A capacity at 60% duty cycle handles flux-cored and solid wires with ease.
• Standard Parts: Uses common front-end consumables to keep operating costs low.
• User-Friendly: Simple trigger mechanism and rotatable neck for difficult angles.

Whether you are replacing a worn-out torch or outfitting a new machine, the P4-15T delivers the power and durability required for serious welding tasks.
