All

*Simple & robust** — relies on a heavy line-frequency copper transformer, with fewer electronic components to fail.

*Bulky & heavy** — typically 30 kg or more, difficult to move around job sites.

*Basic control** — output is usually regulated by taps or timers, with limited precision.

*Lower efficiency** — higher no-load losses and greater energy consumption.

*Best for** — basic, low-volume PE pipe joining where portability and precision are not critical.

Customers recently visited the WELPING factory to explore our production facilities, pipe fusion equipment, and manufacturing process. The visit included an on-site factory tour, product discussions, and face-to-face communication about equipment applications and future cooperation.

Meet Gruv-One RG-4M, the ultra-compact manual roll groover built for tight spaces. With a 1 1/4"–6" grooving range, a lightweight 10 kg design, and just 90 mm of required clearance, it can go where many conventional groovers simply can’t. Designed for pipes already installed in the air, Gruv-One makes In-The-Air grooving easier, lighter, and a lot less frustrating.

A closer look at the WP450B hydraulic butt fusion machine through a new set of product photos, covering the complete machine setup, clamping frame, hydraulic power unit, reduction inserts, facer, heating plate, and key component details.

Gruv Max, your reliable partner for big-diameter and thick-walled pipes.

A new customer inquiry for the WP315A Pro came after a recommendation from another user. The feedback highlights the value of real field experience when customers choose butt fusion equipment.

A real-world look at the FX200 HDPE butt fusion machine, with a focus on the finished pipe joint and the key visual points to check on the fusion bead after welding.

The AG-8Z is a compact, fully automatic roll grooving machine with a 2"-12" standard grooving range, expandable to 1"-14", featuring the Gruv-X® hydraulic system, 32 RPM operating speed, and both wireless and wired control for efficient pipe processing on job sites and in workshops.

Clamp Insert Options for Large-Size Butt Fusion Machines: Steel, Aluminum and Anti-Slip Pads

A practical butt fusion machine is about more than welding range and power. This article takes a closer look at the WP200B, focusing on stable pipe clamping, hydraulic pressure control, multi-size capability and a complete setup for everyday PE pipe fusion work.

Welping’s new smart butt fusion data logger is entering real-order validation, with upgraded touchscreen operation, real-time temperature and pressure monitoring, flexible data management, remote support, and both wired and AP/Wi-Fi configurations.

Groove quality impacts sealing and safety of stainless steel pipe connections. This brief guide introduces simple visual and measuring checks to verify qualified pipe grooves.

A closer look at the WP800A large-diameter butt fusion machine, covering its four-clamp frame, hydraulic power unit, clamping inserts, facing tool and heater plate arrangement. The article explains how these practical design details support stable pipe handling, controlled fusion pressure and smoother operation throughout the complete PE pipe fusion process.

Large hydraulic butt fusion machines are suitable for intensive and large-diameter pipeline construction. However, for small and medium-diameter pipes, irrigation projects, repair work and locations with limited working space, a compact manual machine can provide a more practical solution.
