§4.3.3 Manipulation of electrode
In MMA welding, there are three
motions to being matched in the
end of electrode: the electrode
moving to the molten pool along
axes; the electrode swing right and
left; the electrode moving along
welding way.
The operator can choose the
manipulation of electrode based on
welding joint sharp, welding
position, electrode spec, welding current and operation skill, etc.
The details please refer to Welding Dictionary P69, Volume 1 of Edition 2.
