B-2 OPERATION B-2
INVERTEC V200-T
Power Switch/Voltage Selector Switch - Controls
the power input to the machine. This rotating switch is
used to turn the machine on and off as well as to
select the input voltage. The switch is located on the
top right rear panel. When power is applied to the
machine the Power LED is on.
Welding Current Potentiometer - Potentiometer
used to set the value of the current required by the
welding process. This current setting will be displayed
on the Digital Display. When an Amptrol is used to
remotely control the welding current, this setting con-
trols the maximum welding current when the Amptrol
is fully depressed.
Voltage out of spec/ Overheated LED - This LED
will light up when:
A) The input supply voltage is not within limits
pre-set for correct operation.*
B) The machine is overheated as detected by
the internal thermostat.
* Note that input voltages that exceed 20% of nominal
may cause internal damage to the machine.
Output Terminals - These quick disconnect terminals
provide connection points for the TIG Torch and work
cables or electrode and work cables. For TIG welding,
connect the torch to the DC- terminal and the work
cable to the DC+ terminal. For stick welding positive
polarity connect the electrode cable to the positive ter-
minal and the work cable to the negative terminal. To
weld negative polarity reverse the electrode and work
cables.
Remote Control Connector - This receptacle will
accept a Lincoln Foot Amptrol, Hand Amptrol or Arc
Start Switch. See the ACCESSORIES section for
available options.
