Product Information
Full details
The Knipex Welding Grip Pliers (42 14 280) are professional-grade locking pliers designed for metalworkers and welders who require a secure, hands-free hold on diverse profiles during fabrication. These pliers offer exceptional clamping force and heat resistance, making them an indispensable tool for holding sections, pipes, and plates; however, their heavy-duty steel construction makes them significantly heavier than standard hand tools, which may cause fatigue during prolonged overhead use.

FAQs
What is the maximum jaw opening for this tool?
These pliers are designed to hold material with vertical webs up to 25mm in height.
Are these pliers safe to use on delicate surfaces?
No. Due to the high clamping pressure and steel construction, these pliers are likely to leave marks on softer metals or finished surfaces.
Does the 280mm length include the adjustment screw?
Yes, the 280mm measurement is the overall length of the tool.
Can I use these for gripping hot metal immediately after welding?
Yes, the malleable cast iron jaws are heat-resistant, but ensure you handle the steel handles with care as they may conduct heat.
How heavy are these pliers?
They weigh 917 grams, reflecting their heavy-duty, high-strength construction.
Troubleshooting
Pliers will not lock securely.
Rotate the adjustment screw clockwise to increase clamping pressure before engaging the locking lever.
The release lever is stuck.
Apply a small amount of penetrating oil to the release lever pivot and work it back and forth to loosen any dried residue or weld spatter.
Pros and Cons
Pros
- Extremely durable construction suitable for industrial use
- Heat-resistant jaws prevent deformation during high-heat tasks
- High clamping pressure ensures materials do not slip during welding
- Easy to adjust for varying material thicknesses
- Reliable one-handed locking mechanism
Cons
- Substantial weight (917g) can be tiring during extended use
- Steel handles may become hot if used near intense heat sources
- Not intended for delicate work where surface marking must be avoided
Setup, Compatibility & Care
To set up the pliers, rotate the adjustment screw at the end of the handle while the jaws are open to calibrate the clamping pressure to your specific workpiece thickness. Once set, close the pliers until they click into the locked position. To release, simply pull the release lever firmly.
Care Instructions:
- Regularly inspect the pivot points and the adjustment screw for debris; keep them lubricated with a light machine oil to maintain smooth operation.
- After use in welding, brush away any spatter or slag from the jaw faces to ensure a clean grip next time.
- Store in a dry environment to prevent surface corrosion, despite the heavy-duty finish.
