61040 - Piher Maxipress R 40 High-Performance Piston F-Clamp 16-Inch

The Ultimate Welding Clamp: Spatter-Proof and Powerful

For professional welders, equipment longevity is often determined by how well it survives the heat and spatter of the job. The Piher Maxipress R 16" Welding Clamp is designed specifically to solve the most common failure point of welding clamps: thread damage. Traditional open-screw clamps quickly become useless when molten weld spatter adheres to the threads, preventing the clamp from tightening or loosening. The Maxipress R eliminates this problem entirely with its protected piston system. The screw thread is fully housed inside the piston, meaning no amount of spatter, grinding dust, or dirt can reach the mechanism. This guarantees that your clamp operates as smoothly on day 1000 as it did on day 1.

Beyond its durability, this clamp is a powerhouse in the fabrication shop. With a clamping capacity of 16 inches (40 cm) and a throat depth of approximately 4.72 inches (12 cm), it handles a wide range of assembly tasks. The tool delivers a crushing 2200 lbs (1000 kg) of pressure, allowing you to pull stubborn steel members into alignment before tacking. The ergonomic handle is designed to let you apply this maximum force comfortably, reducing hand fatigue during long fit-up sessions. The handle also features a multi-position grip that is easy to turn even when wearing heavy welding gloves.

Stability is key during fit-up, and the Piher Maxipress R delivers. The non-slip brake on the sliding head ensures that once you position the jaw, it stays put, preventing the annoyance of the jaw sliding open just as you try to set your piece. The jaws are made from high-strength nodular cast iron, capable of withstanding the thermal cycles and rough handling typical of a welding environment. Whether you are fabricating structural steel, assembling frames, or performing heavy repairs, the Piher Maxipress R provides the reliability and force you need to get the job done right. Stop replacing seized clamps and upgrade to the piston system that lasts.
