Electrical Connection
Your Invertig 160DC can operate on either 110-volt or
single-phase 230-volt power. The machine comes from the
factory set up for 230-volt operation and is not shipped with
a plug. The input power cord has 3 wires. The yellow-green
wire is ground, and the blue and brown wires are the
hot leads.
To change the machine from 230-volt operation to
110-volt operation, follow the following steps:
1) Be sure the machine is un-plugged from the power
supply and the power switch is in the “0” position.
The power switch must remain in the “0” position
until the procedure has been completed.
2) Remove the phillips head screw which holds the
on-off knob on and remove the knob. (See Fig. 1)
3) You will see a plastic disc with 2 elongated slots in
it. The disc should be in the 230-volt position.
(See Fig. 2)
4) Flip the disk over so it is in the 110-volt position.
(See Fig. 3)
5) Replace the knob. Be sure the machine has the
correct plug installed and it is set for the voltage
which you will be using. Attempting to operate the
machine on the wrong voltage will cause damage to
the machine and is not covered under warranty.
6) Check to make sure the switch rotates to the correct
voltage before plugging your Invertig 160DC into
the power supply.
All electrical connections should be performed by a
qualified electrician in accordance with the National
Electrical Code and local codes and ordinances.
When set to operate the machine on 110-volts, do not
exceed 130 amps when TIG welding and 90 amps when
arc welding.
