Below are my favorite welding clamps I like and use, updated December 27, 2022.
Maxpower F Clamps
The Maxpower F Clamp is a great clamp to use for welding. They are well-built and they work great for jigging and holding things down tight.
These clamps come in multiple sizes from 12″ to 24″ long. With a load rating of 2400 pounds, these clamps are going to hold up to almost any project you have.
Best of all these are priced cheaper than the normal Bessy clamps and do just as good of a job.
