Welding Clamps

About Welding Clamps

Welding clamps are essential tools designed to hold metal workpieces firmly in position during welding, brazing, and fabrication work. Built to withstand extreme heat, spatter, and the demanding conditions of welding environments, these specialised clamps ensure accurate alignment and stable positioning throughout the welding process. MyToolShed.co.uk stocks a comprehensive range of welding clamps from trusted brands including Draper, Sealey, Faithfull, and Vise-Grip.

This category features specialist welding clamps that differ from standard workshop clamps, including earth clamps for electrical grounding, magnetic welding clamps for hands-free positioning, self-grip sheet metal clamps, and complete welding clamp sets. Whether you're working with MIG, TIG, or MMA welding equipment, having the right clamping solutions is crucial for achieving professional results and maintaining workplace safety.

Applications

Welding clamps are used across various trades and industries:

• Professional welders and fabricators working in manufacturing, construction, and metal fabrication shops
• Automotive repair and restoration specialists requiring precise panel alignment
• Structural steel workers and architectural metalworkers
• Agricultural and plant maintenance engineers performing repair welding
• DIY enthusiasts and hobbyists tackling home welding projects
• Sheet metal workers joining thin gauge materials
• Pipeline welders and pressure vessel fabricators

Choosing The Right Welding Clamps

When selecting welding clamps from MyToolShed.co.uk, consider these important factors:

• Clamp type: Earth clamps provide electrical grounding for 240v welding equipment, magnetic clamps offer hands-free positioning at various angles, whilst self-grip clamps secure sheet metal and thin materials
• Current rating: Earth clamps are rated by amperage capacity (typically 200A to 400A) – ensure your clamp matches your welding machine's output
• Magnetic strength: Measured in kilograms of holding force – stronger magnets provide more secure positioning on heavier workpieces
• Material construction: Look for heat-resistant materials, copper contacts for earth clamps, and robust steel construction for longevity
• Opening capacity: Check the maximum jaw opening or material thickness the clamp can accommodate
• Set options: Multi-piece sets offer versatility and better value for comprehensive workshop requirements

Safety Information

Always ensure earth clamps are securely attached to clean, unpainted metal surfaces to maintain proper electrical grounding. Inspect clamps regularly for damage, worn contacts, or compromised insulation. Never use damaged clamps with 240v welding equipment as this creates serious electrical hazards. Magnetic clamps should be positioned securely to prevent workpiece movement during welding. Wear appropriate PPE including welding gloves when handling hot clamps and recently welded materials.

Frequently Asked Questions

What's the difference between an earth clamp and a ground clamp?

These terms are interchangeable – both refer to the clamp that connects the earth return cable from your welding machine to the workpiece, completing the electrical circuit necessary for arc welding.

Can I use magnetic welding clamps on stainless steel?

Magnetic clamps work on ferrous (magnetic) metals like mild steel and cast iron, but most stainless steel grades are non-magnetic and won't hold reliably. Use mechanical clamps for stainless steel fabrication work.

How many welding clamps do I need?

This depends on your project complexity. Simple joints may need just 2-3 clamps, whilst complex assemblies benefit from 4-6 or more. Multi-piece welding clamp sets provide excellent value and versatility for varied fabrication work.
