4. Setup
The Rothenberger ROWELD Double Clamp is designed for straightforward setup.
- Unpacking: Carefully remove the clamp from its packaging. Inspect for any shipping damage.

5. Operating Instructions
Follow these steps for effective use of the double clamp:
- Prepare Workpiece: Ensure the pipes or workpieces to be joined are clean, free of burrs, and properly prepared for welding or joining.
- Position Clamp: Place the clamp around the two workpieces you intend to align. The jaws should engage both pieces simultaneously.
- Adjust and Secure:
- Slowly tighten the adjustment mechanism until the workpieces are firmly held and perfectly aligned.
- Ensure even pressure distribution to prevent distortion.
- Do not overtighten, as this can damage the clamp or workpiece.
- Verify Alignment: Double-check the alignment of the workpieces before proceeding with welding or joining.
- Release Clamp: After the operation is complete and the joint has cooled (if applicable), loosen the adjustment mechanism to release the clamp.
6. Maintenance
Proper maintenance ensures the longevity and reliable performance of your clamp.
- Cleaning: After each use, clean the clamp to remove any welding spatter, dust, or debris. Use a wire brush for stubborn residue, if necessary.
- Lubrication: Periodically apply a light coat of machine oil to the adjustment screw and other moving parts to ensure smooth operation and prevent corrosion.
- Inspection: Regularly inspect the clamp for signs of wear, cracks, bends, or other damage. Pay close attention to the jaws and adjustment mechanism.
- Storage: Store the clamp in a dry, protected environment to prevent rust and damage.
7. Troubleshooting
This section addresses common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Clamp not holding workpiece securely. | Insufficient tightening; workpiece O.D. outside range; worn jaws. | Tighten adjustment mechanism further (without overtightening); verify workpiece O.D. is 50mm; inspect jaws for wear and replace clamp if necessary. |
| Adjustment mechanism is stiff or difficult to turn. | Lack of lubrication; dirt/debris in threads; minor corrosion. | Clean threads thoroughly; apply machine oil to the screw mechanism. |
| Workpieces are misaligned after clamping. | Improper positioning of clamp; uneven tightening; workpiece irregularities. | Reposition clamp for better engagement; ensure even tightening; prepare workpiece edges properly. |
