OVERVIEW

Efficient Grounding for Rotary Applications

The Tweco Roto-Ground Head (TWE9922-2124) is a specialized grounding device engineered to solve one of the most persistent challenges in pipe and vessel fabrication: cable management during rotation. When welding cylindrical objects like pipes, tanks, or shafts that are mounted on turning rolls or positioners, standard ground clamps rotate with the workpiece. This inevitably leads to twisted, tangled, and eventually damaged welding cables. The Roto-Ground Head eliminates this issue entirely by allowing the grounding head to rotate freely with the workpiece while the welding cable remains stationary.

Heavy-Duty Construction

Built by Tweco, a leader in welding accessories, this Roto-Ground Head is constructed from high-conductivity copper alloys. This ensures that it can handle the high amperage currents typically required in heavy industrial fabrication without overheating. The robust design is intended for harsh shop environments, resisting wear and tear from constant rotation and electrical transfer. It maintains a low-resistance connection, which is critical for arc stability and weld quality, especially in automated or semi-automated processes.

Versatile Installation

This device is an essential component for any shop utilizing automated fixtures, pipe rollers, or chucks. It can be easily adapted to various fixtures, ensuring that the ground current flows directly into the workpiece without passing through bearings or other sensitive equipment components, thereby preventing arc damage to the machinery itself. Whether you are welding stainless steel piping or heavy-wall pressure vessels, the Tweco Roto-Ground Head ensures your operation runs smoothly without the interruption of untangling cables.

Key Benefits

  • Prevents Cable Damage: Stops the twisting and snapping of copper strands inside welding cables.
  • Protects Equipment: Directs current safely to the workpiece, bypassing fixture bearings.
  • Consistent Arc: Maintains steady electrical contact for defect-free welds.

FAQ

It is designed to provide a continuous ground connection for rotating workpieces, such as pipes or tanks, preventing the welding ground cable from twisting or tangling.

By providing a direct path for the welding current to the workpiece, it prevents the current from passing through the bearings or gears of your turning rolls or positioners, which could cause arcing and damage.

It is typically constructed from high-conductivity copper alloys to ensure efficient current transfer and durability under high heat.

Yes, it is excellent for manual pipe welding on rollers, as it allows the welder to rotate the pipe continuously without worrying about the ground clamp.

The term 'Head' often refers to the main contact assembly. Please verify if you require additional mounting studs or cables depending on your specific fixture setup.

Tweco Roto-Grounds are generally rated for high amperage (often 800A to 2000A depending on the specific model series). Check the specific datasheet for the 9922-2124 rating.

Yes, like all electrical connections, the contact surfaces should be kept clean and the tension adjusted periodically to ensure low resistance.

It is usually mounted to the stationary part of the fixture or the end of the pipe, with the stationary cable lug attached to the non-rotating portion of the device.
