60150 - Piher Maxipress F Heavy Duty Piston Clamp 60 Inch Opening

The Ultimate Welding Clamp: Piher Maxipress F 60150

In the harsh environment of a welding fabrication shop, standard clamps often fail due to the accumulation of weld spatter, dust, and debris on exposed threads. The Piher Maxipress F Clamp (SKU: 60150) is specifically engineered to solve this problem, making it an indispensable asset for professional welders and fabricators. The defining feature for the welding industry is the fully enclosed piston system. By housing the threaded mechanism completely inside the protective cylinder, Piher ensures that weld spatter cannot adhere to the threads, preventing the seizing and damage that plague conventional open-screw clamps. This design guarantees smooth operation and a long service life, even when used in close proximity to MIG, TIG, or Stick welding arcs.

Fit-up is a critical stage in welding, requiring tools that can exert tremendous force to align heavy steel plates and structural members. The Maxipress F delivers a crushing 2,250 lbs (1,000 kg) of clamping pressure, ensuring that joints are tight and gaps are eliminated before the arc is struck. This high-pressure capability is achieved through a double-threaded screw design that multiplies the torque applied by the user, allowing for rapid tightening and maximum force with minimal physical exertion. The 60-inch (150 cm) opening capacity makes this specific model ideal for large weldments, frames, and jigs where standard clamps fall short.

Versatility in gripping different shapes is essential for fabricators. The Piher 60150 features a fixed jaw with a specialized "+" groove, allowing it to bite securely into pipes, tubes, and angled profiles—common materials in structural fabrication. The jaws themselves are made from epoxy-coated cast iron, providing a robust shield against heat and corrosion. The curved design of the jaw heads allows the clamp to reach around flanges, stiffeners, and other protrusions, providing pressure exactly where it is needed without obstruction.

Safety and stability are paramount when handling heavy steel components. The moving jaw is equipped with a reliable non-slip brake system that holds the jaw in position before pressure is applied, preventing it from sliding down and pinching fingers or losing the setup. The heavy-duty steel rail (35mm x 8mm) resists bending under load, ensuring that the clamping force remains constant throughout the welding process. With a greasing port for easy maintenance and a reversible handle for better access in tight corners, the Piher Maxipress F is not just a clamp; it is a dedicated fabrication tool built to withstand the rigors of the modern welding shop.
