5 Best Welding Ground Clamps: 2022 Buyers Guide & Reviews

Best Welding Ground Clamps – When a connection is established between the equipment enclosure and the ground, it ensures that the metal enclosure of the machine and the ground are at the same potential.

This is done so that a person can avoid getting an electrical shock when they touch both points.

If the enclosure is grounded, the voltage on the enclosure is limited. This can be seen as a precaution in case the equipment insulation fails.

If you can use the correct welding ground clamp, you will have the best projects. Besides, it protects you against welding current restrictions, Poor welds, and leakages.

You have to note that different welding projects might require various types of ground clamps.

Look no further to know about the best welding ground clamps. Down below, we have listed the best ground clamp for welder.

4. Tweco 9205-1120 GC-200 Welding Ground Clamp, 200-Amp Capacity

This welding clamp is available in both 200-amp capacity and 300-amp capacity.

This can be used in many forms of welding like submerged arc welding, gas metal arc welding, stick welding, and gas tungsten arc welding.

This welding ground clamp is perfect for light and medium-duty metal fabrication. The max jaw opening is up to 1 inch. It has a Ballpoint screw that helps secure the welding Cable to the ground Clamp.

The Tweco 9205-1120 GC-200 Welding Ground Clamp has a rugged and reliable copper cast design. It also has a ballpoint screw to secure the welding cable to the ground clamp. A heavy-duty insulated spring is also included.


Perfect for light and medium-duty metal fabrication

Amperage Capacity is ‎200 Amps

5. ESAB 92051130: GC300 300A JR Ground Clamp Copper

ESAB GC300 is available in either a 200-amp or 300-amp capacity.

This had to be included among the top 5 ground wire clamps. This one has a 300amp capacity and is a well-built and heavy-duty clamp. It also comes with a heavy-duty insulated spring.

This is a great upgrade option for people using lower-quality factory clamps that come with welding units. The ESAB GC300 is stout. It, therefore, requires huge grip strength to open all the way.

It can be used for submerged arc welding, stick welding, Gas metal arc welding and Gas Tungsten arc welding applications.

This clamp is copper cast and thus has superior conductivity compared to brass. However, this welding clamp comes with a higher price tag which is worth it, keeping in mind the performance increase, durability, and sturdiness.


Is of superior quality and ideal for heavy-duty use.

Amperage Capacity is ‎300 Amps

Things to consider while buying

You must keep in mind that all electrical welding current flows through the ground clamp.

If there is no suitable ground connection, the welder’s performance and the welding machine will not be that great. This will result in inferior welds.

Ground clams that do not work properly can cause current welding limitations and even leakages. In simple words, a ground clamp that works poorly will lead to a decline in welding output voltage.

To avoid falling into this situation, you need to have a reliable cable lug for your welding ground clamp. The lug has to fit the cable securely. This will keep the lug bolt or terminal from becoming loose. In addition, you would want to have a clamp accompanied by a firm cable connection that can withstand high cable strain.

You must keep a good look at finding a welding ground clamp manufactured with sturdy material and has a good clamp design.

Most welders prefer a solid brass cable terminal and Jaws. It is preferred by most because it provides a direct and reliable current flow. On a final note, you must have your clamp equipped with a solid clamp spring and clamp jaws that will not fall prey to corrosion.

Having a suitable lead work clamp is necessary for safe and proper welding. Many workers like using either brass or a bronze C-clamp style ground. Some also like using a magnetic ground with a rotary connection. The reason is that a high-quality spring clamp is less likely to cause disfiguration of the metal surface.

The copper strips connecting the cable to the clamp are generally not given much importance. Still, these copper strips play a role in reducing the heat buildup on your work lead clamp.

Some welders also look for line connectors with the “twist and lock” mechanism. This line connector connects a cable to cable or a cable to ground clamp. Also, it provides a more secure connection and can handle high electric currents of up to 150 amperes.

There is also another type of ground clamp, which is ideal for high current Welds. It is designed like a Screw clamp and is made of bronze.


From the beginning, we have mentioned quite a few times that safety should be paid the utmost importance in case of any welding process. However, a Welding ground clamp does more than just ensure the welder’s safety. A ground clamp plays a massive role in maintaining consistent welding currents throughout the welding process.

Before taking up any welding project, a welder should know all the basics of welding ground clamps. They should also know which ground clamp is best suited for which type of project.

Ultimately we would say that having a good weld is never possible with a lousy clamp in your possession.
