What Is a Spot Weld Cutter?
A spot welder is a tool that transfers heat through copper alloy electrodes to weld two or more sheets of metal without the use of additional filler. The heat comes from an electrical current.
Spot weld cutters are specifically designed to remove those spot welds without using a rotary cutter, making the job neater, faster and easier.
Spot welding is one of the oldest welding methods, and it works best with thin sheet material, which is why you see it commonly used in the automotive manufacturing industry. It is also an ideal method of making temporary welds.
How To Choose the Best Spot Weld Cutter
It is a challenge defining what makes the best spot weld cutter in one word. Several factors are at play here, but there are some basics you should consider.
How To Use a Spot Weld Cutter
Locate the spot welds you want to remove, and using a drill and small bit, drill a pilot hole in the center of the spot weld. Sweep away any strands of metal. Insert your weld cutter into the same drill, and using the pilot hole as a template, drill down until the teeth have ground away from the weld material.
Some kits have centering tips included to make neater and more accurate cuts. The best cutters will leave the spot weld smooth and burr-free.
