Product details
An MMA (Manual Metal Arc) welding machine, also known as a stick welder or SMAW (Shielded Metal Arc Welding) machine, is a power source that provides electricity to create an arc between a coated electrode and the metal being welded. This arc melts the metal, creating a weld. The electrode's coating provides shielding from atmospheric contamination and forms a slag layer that is removed after welding.
