    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 Tip—Pointed tip electrodes are the most common electrodes. All are good for most applications, including small welds.
    Flat Tip—Flat tip electrodes create larger welds than pointed electrodes and are best when the weld appearance is less important.
    Offset Tip—Those with offset tips are best for spot welding near edges and corners.
    Double-Bent Tip—Others with double-bent tips can reach over a lip or into tight, enclosed areas where straight tips are not able to access both sides of your metal.
    Swivel Tip—Those with swivel tips compensate for misalignment and reduce markings on your metal.

    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 Tip—Pointed tip electrodes are the most common. They’re good for most applications, including small welds.
    Flat Tip—Flat tip electrodes create larger welds than pointed tips and are best when the weld appearance is less important.
    Female—When used with water-cooled spot welders, female tips are less likely to spill water than male tips when swapping them out.
