1. Definition: Manual arc welding is a welding method that uses the arc heat between the welding rod and the materialto melt the welding rod and part of the materialto form a weld.
2. Characteristics of manual arc welding:Manual arc welding has the advantages of simple equipment, flexible operation, low cost, and good weld ability. There are no special requirements for the assembly dimensions of the welded joints. It can be welded in various positions under various conditions and is suitable for a variety of steel materials and non-ferrous metals. Metal.Manual arc welding has strong arc light and smoke pollution, unstable welding quality, short and discontinuous welds, uneven weld widths, poor working conditions, high labor intensity, low productivity, and high technical requirements for workers.

3. Type of power supplyCommonly used manual arc welding power sources are divided into DC welding machines and AC welding machines according to the output current type.
