6.2.2 Welding Operation
(1) Adjust “welding current onto suitable value according to work piece
thickness and electrode diameter (refer to Table 8)”. Could adjust striking
arc current properly to ensure reliable striking arc.
(2) The machine uses inverter control by adjust “arc force” to control
stiffness of arc and change metal transfer process to ensure welding
process running stably.
(3) While welding on all position, adjust “arc force” value bigger to avoid
conglutination between electrode and work piece; while welding in large
current or flat welding, adjust “arc force” value smaller or onto zero
position to decrease splash.
6.3 GTAW operation
6.3.1 Preparation
(1) Connect machine according to FIG 3.
(2) Shift “MMA/TIG/CO2” switch onto “MMA” model.
(3) Switch on the power supply MCB, the machine’s “power” indicator turns
light, cooling fan begins running.
(4) Select suitable dock needle and filler wire according to work piece.
(5) Adjust welding torch flow switch and select suitable flow. Shift switch
onto “off” position when not use.
6.3.2 Welding Operation
(1)Adjust “welding current” onto suitable value according to work piece
thickness(refer to table 9)
(2)The operation is : contact tungsten with work piece, press torch switch,
scratch work piece and uplift torch, the arc is ignited. Uplift torch when arc
is broken, elongate arc, force to broke arc.
