Welding of lead is very similar to welding other metals, except that there is no flux. Other than gas welding, these processes are not generally used. The color of unfinished surfaces (white to gray), newly fractured surfaces (light gray, crystal), and freshly filed surfaces (white) can all be used to identify lead. Example of Lead … Read more
This type of welding requires approximately twice the heat as the steel of similar thickness. Copper is very thermally conductive. A tip that is one to two times larger than the steel tip is recommended in order to offset heat loss. Additional heating is recommended when welding large sections with heavy thicknesses. This produces a … Read more
A 120V welder is a good choice for small shops or hobbyists. If you have a small welding business or hobby, you will need more power and the ability to weld thicker material. This allows you to increase your voltage to 240V without sacrificing the ability to weld thinner stocks. These needs are well met … Read more
