10.1.5 Adjusting Welding Voltage
Using the VOLT. CONTROL key [14] allows you to select one of the following voltage
adjustment methods.
(1)Making the INDIVIDUAL Adjustment
The INDIVIDUAL adjustment can be achieved when the VOLT.CONTROL lamp (located at
the upper left of the VOLT. CONTROL key [14]) is off. In the case of the INDIVIDUAL
adjustment, welding current and welding voltage must be adjusted individually. When you
want to set welding voltage, make sure that the VOLT. CONTROL lamp is lit, then adjust the
welding voltage while turning the parameter adjusting knob [6]. When you want to set welding
voltage, make sure that the VOLT. CONTROL lamp is lit, then set welding voltage while
turning the parameter adjusting knob [6].
NOTE: When selecting HARD ALMINUM or SOFT ALUMINUM, the INDIVIDUAL
adjustment can not be achieved. The SYNERGIG adjustment function is automatically
activated.
(2)Making the SYNERGIC Adjustment
The SYNERGIC adjustment can be achieved when the VOLT. CONTROL lamp (located at
the upper left of VOLT. CONTROL key [14]) is on. For the SYNERGIC adjustment, the proper
welding current for the current setting is automatically set. When the VOLT. CONTROL lamp
is lit, welding voltage can be finely adjusted using the parameter adjusting knob [6]. In
addition, it is also possible to change over the display setting in the right display using the V/r
selector key [5]. The selectable display settings are the INDIVIDUAL mode (V) and the
SYNERGIC mode (r adjustment) . In the SYNERGIC display mode, the standard value is 0.
The setting range of welding voltage is 0 to r30 .
NOTE: Use of mixture gas other than the mixture ratio of the following gas may not
properly adjust welding voltage at Synergic control, etc.
