4.1.1 poWer sWItch
The front panel Power Switch energizes the primary of the
main transformer, the control circuits, the wire feed circuit,
gun trigger circuit and the cooling fan.
When switched to the "ON" position the machine is in the
ready to weld mode.
When switched to the "OFF" position, primary input voltage
to the main transformer is interrupted and the unit will be
inoperable. However, primary voltage will still be present
inside the cabinet up to the switch.
4.1.2 Voltage control (coarse range selector
and fine adjustment range selector)
Voltage control is by means of two high current tap switches
which connect the rectifier bridge to eight secondary
taps.
The coarse Voltage range selector is a three-position
switch, (1) LOW / (2) MED / (3)HIGH, which selects the range
of voltage (or heat, that determines the arc length) to be ap-
plied to the weld. It is a coarse selection control and is used
in conjunction with the Fine Voltage Adjustment selector
following. It must not be switched under load.
