Product Information
Full details
This Power-TEC Shunting Clamp is designed for automotive repair professionals working with E-coat steel. Its key benefit is significantly speeding up spot welding repairs on E-coated steels by allowing welding without full E-coat removal. A caveat is that proper current flow depends on correct clamp placement, which requires understanding the process.

FAQs
Do I need to remove all E-coat before using this clamp?
No, the primary benefit of this clamp is that you only need to remove the E-coat from the outer surfaces where the clamp makes contact. This significantly speeds up the repair process compared to removing E-coat from the entire panel.
What materials can this clamp be used on?
This shunting clamp is specifically designed for spot welding E-coat steel. Its effectiveness on other coated materials may vary.
How do I ensure a good weld?
A good weld is achieved by ensuring clean contact surfaces for the clamp, proper clamp placement to facilitate current flow, and correct settings on your spot welding equipment.
What are the dimensions of the clamp?
The clamp has an overall length of 280mm, a reach of 80mm, and a width of 85mm.
What is the clamp made of?
The clamp is manufactured from chrome molybdenum, with its jaws made from chrome vanadium.
Can this clamp be used with any spot welder?
It is compatible with standard spot welding equipment. However, you must ensure your equipment's power output and settings are appropriate for the E-coated steel you are working with.
How should I maintain the clamp?
Clean the jaws after each use to remove debris, inspect for damage, and store in a dry environment to prevent corrosion.
Troubleshooting
Poor weld quality or no weld at all.
Ensure the E-coat has been adequately cleaned at the clamp contact points. Verify the clamp is securely fastened and making good metal-to-metal contact. Check that the spot welder settings (amperage, time, pressure) are appropriate for the material thickness.
Clamp not properly shunting current.
Re-examine the placement of the clamp. Ensure it is positioned to create a direct path for the current between the two surfaces to be welded. Clean the contact surfaces again thoroughly.
Excessive heat or sparking at contact points.
This may indicate too much E-coat remaining or improper contact. Reduce the welding current slightly or ensure cleaner contact surfaces. Check for any debris between the clamp and the metal.
Jaws of the clamp are damaged or worn.
Inspect the jaws for any deformation or excessive wear. If damaged, the clamp may not function correctly or safely. Contact the manufacturer or supplier for replacement parts or a new unit.
Pros and Cons
Pros
- Reduces E-coat removal time for faster repairs.
- Ensures strong and consistent spot welds on E-coated materials.
- Durable materials for extended tool life.
- Designed for efficient workflow in automotive repair settings.
- Improves productivity on E-coated steel repairs.
Cons
- Requires careful placement to ensure proper current shunting.
- Primarily designed for E-coat steel, may not be suitable for other materials.
- Initial learning curve for optimal E-coat surface preparation.
- Specific application may require other specialized tools.
- No integrated power source; requires connection to a spot welder.
Setup, Compatibility & Care
Setup:
- Ensure your spot welding equipment is compatible with the shunting clamp's current requirements.
- Identify the precise locations on the E-coated steel where the clamp will attach.
- Clean only these specific contact surfaces, removing any grease or debris, but leaving the surrounding E-coat intact.
- Attach the Power-TEC Shunting Clamp securely to the prepared surfaces, ensuring good metal-to-metal contact.
- Connect your spot welding gun to the workpiece as per standard procedure, ensuring the weld is initiated through the clamp's contact points.
Compatibility:
- Primarily designed for use with E-coated steels in automotive repair.
- Compatible with standard spot welding equipment.
- Ensure the workpiece thickness and material are within the specifications of your spot welder and the clamp's capabilities.
Care:
- After each use, clean the jaws of the clamp to remove any weld spatter or debris.
- Inspect the clamp regularly for any signs of damage or wear.
- Store the clamp in a dry place to prevent corrosion.
- Avoid exposing the clamp to harsh chemicals that could degrade the material.
