1.
Put the AC/DC alter switch to the “AC” position as the above1-4 instruction items; there is AC arc
welding for the aluminum.
2. Adjust the cleaning pulse width knob according to the oxidation degree of the surface on the work
piece: during the AC arc welding, the current alters continuously. When the current flows from the
tungsten to the work piece, the current is in the positive direction, the heat is concentrated and it is
apt for welding. When the current flows from the work piece to the tungsten, the current is in the
negative direction, and the tungsten can be cleaned and is helpful to achieve the excellent welding
effect. However, the tungsten may be burned on account of extreme heat. This knob is used to adjust
the time of positive and negative current.
3. Same as the above10-12 instruction items.
Note: (1) When the current is heavy, please choose larger pulse duty.
(2) AC argon arc is hard to initiate, please set the current value to 20A to weld.
