An MMA welding machine is a type of electric welding machine used for Manual Metal Arc (MMA) welding, also called stick welding or SMAW (Shielded Metal Arc Welding).
What it does
An MMA welding machine creates an electric arc between a consumable electrode (welding rod) and the metal you are joining. The heat from the arc melts both the rod and the base metal, forming a strong weld joint.
The rod has a special coating (flux) that:
Protects the weld from air contamination
Creates a shielding gas
Forms a slag layer that is chipped off after welding �
