All ARC/MMA Welding Machines, Spares and Cosumables
ARC Welding known as MMA stands for “Manual Metal Arc” this is an electric process by which an electric arc is struck between the welding electrode and the workpiece.
The central metal electrode or core wire provides a filler metal for the weld and the electrode coating provides a shielding pool made up of the weld slag.
This Welding process operates with DC or AC power sources, most commonly DC. MMA welding provides a limited amount of weld metal deposited from one electrode and electrodes need to replaced frequently, making it a less productive process than other methods of welding.
The MMA process is also used for hard surfacing, gouging, cutting of ferritic alloys.
