OVERVIEW

Reliable Power for Your Lincoln Feeder

If you are running a Lincoln LF72 or LF74 wire feeder and want the rugged reliability of a Tweco-style gun without the hassle of mismatched connectors, the PT4015LPB is your answer. This 400 Amp MIG gun is built to handle the heat of high-deposition welding while offering the convenience of a direct-fit solution. With a 15-foot lead, you gain the flexibility to move around large weldments and fixtures without constantly dragging your feeder across the shop floor. It’s the perfect upgrade for welders who demand performance and durability.

Standard Consumables, Lower Costs

Tired of overpaying for proprietary contact tips and nozzles? This gun utilizes the universal Tweco #4 style front-end parts. You can find 14-series tips and 24-series nozzles at practically any welding supply shop, often at a fraction of the cost of OEM specific brands. This means less downtime waiting for parts and more money in your pocket. The heavy-duty nozzle and diffuser design stands up to spatter and heat, ensuring your gas coverage remains consistent for high-quality welds every time.

Plug-and-Play Simplicity

The standout feature of this gun is its "Bell Plug" trigger connection. Many aftermarket guns require you to cut and splice wires to make them work with Lincoln feeders. This unit comes pre-wired with the correct plug for your LF72/74 series machine, paired with a standard Tweco power pin. Just plug it into your feeder's Tweco adapter, connect the trigger, and strike an arc. The ergonomic handle is designed to fit comfortably in a gloved hand, reducing wrist strain during long beads and giving you better control over the puddle.
