MMA Welding Machine
MMA Welding Machin
Although the manual metal arc (MMA) process has relatively basic equipment requirements, it is important that the Welding Machine has a knowledge of operating features and performance to comply with welding procedures for the job and, of course, for safety reasons.
Essential equipment
The main components of the equipment required for welding are:
- power source
- electrode holder and cables
- Welding Machine protection
- fume extraction
Tools required include: a wire brush to clean the joint area adjacent to the weld (and the weld itself after slag removal); a chipping hammer to remove slag from the weld deposit; and, when removing slag, a pair of clear lens goggles or a face shield to protect the eyes (lenses should be shatter-proof and noninflammable).
