Spot Welding Electrodes
Press these electrodes onto the tips of spot welders to change the size and shape of your weld. Their shank is tapered for easy press-fit installation.
Pointed electrodes are the most common electrodes. All are good for most applications, including small welds. Those with offset tips are best for spot welding near edges and corners. Others with double-bend tips can reach over a lip or into tight, enclosed areas where straight tips are not able to access both sides of your metal.
Flat electrodes create larger welds than pointed electrodes and are best when the weld appearance is less important. Those with swivel tips compensate for misalignment and reduce markings on your metal.
Convex electrodes are for joining aluminum, brass, and bronze.

Cap-Style Spot Welding Electrodes
A two-part alternative to standard electrodes, these electrodes reduce waste since you can reuse the shank. For a complete electrode, you'll need a tip and a shank (both sold separately). Press complete electrodes onto the tips of spot welders to change the size and shape of your weld. When the tip becomes worn, only the tip needs to be replaced.
Pointed tips are the most common. They’re good for most applications, including small welds. When used with water-cooled spot welders, female tips are less likely to spill water than male tips when swapping them out.
Flat tips create larger welds than pointed tips and are best when the weld appearance is less important.
