Spot welding, or resistance spot welding, is a welding process used to weld sheet metal by applying heat and pressure with an electric current through a copper alloy electrode.

There are different types of spot welders, spot welders for 18650 batteries are different to hand held squeeze-type spot welders. Squeeze-type spot welders have large metal electrode jaws which go either side of the metal sheets, creating heat and pressure in a small spot to weld them together. Battery spot welders have electrodes on the same side and are typically used for connecting 18650 batteries.

This guide will explain all about Argon gas cylinders and which one is best for you. You will need to use a different type of Argon gas cylinder depending on your welding process. If you’re TIG welding, you’ll typically use 100% Argon. If you’re MIG welding, you’ll typically use an Argon/CO2 mixture.

Many beginner welders don’t realize the damage that can be caused to the eyes by not wearing the sufficient welding safety equipment. The welding arc produces harmful radiation which can damage the eyes and cause the unpleasant “welders flash.” Safety glasses are a way of blocking out UV light and infrared wavelengths emitted from the welding arc. Welding glasses are great because they also protect the eyes from any flying debris and can help reduce irritation from fumes. Updated March 4th 2020
