Arc

MMA or Manual Metal Arc Welding is a flexible and widely used welding process which involves striking an arc between a covered metal electrode and a workpiece. The heat of the Arc melts the workpiece and the electrode, forming a weld pool, which cools and forms the weld joint. As the weld is laid the flux coating on the electrode disintegrates giving off vapours that serve as a shielding gas which provides a layer of slag, both of which protects the weld area from atmospheric contaminants.

We supply a great range of arc welding products, including arc welders, consumables, electrode holders and clamps, which you can browse here.
