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.
