ENGINE DRIVEN GENERATOR
The Inverter machine can be operated on engine
driven generators as long as the 220/230/240 volt
auxiliary meets the following conditions:
. The AC waveform peak voltage is below 400 volts.
. The AC waveform frequency is between 45 and
65Hz.
The following Lincoln engine drives meet these
conditions when run in the high idle mode:
●
Ranger 250,305
●
. Commander 300, 400, & 500
Some engine drives do not meet these conditions
(e.g. Miller Bobcats, etc). Operation of the Inverter
machine is not recommended on engine drives not
conforming to these conditions. Such drives may
deliver unacceptably high voltage levels to the
Inverter machine power source.
CONNECTIONS FOR TIG (GTAW) WELDING
TIG TORCH CONNECTION
Refer to Included Equipment in the Operation
Section of this manual for TIG welding
equipment which is included with the machine
The TIG Torch Twist-Mate and work cable
Twist-Mate Connectors are supplied with the welder.
To connect the cables, turn the Power Switch
“
OFF
”
. Connect the torch cable Twist-Mate plug
into the DC(-)
Electrode Receptacle on the front of the welder and
turn it clockwise until snug,(Do not Over tighten).
This is a quick connect terminal
To avoid receiving a high frequency shock, keep
the TIG torch and cables in good condition.
WORK CABLE CONNECTION
Next, connect the work cable to the
“
+
”
output
terminal in the same way.
To minimize high frequency interference, refer to
Machine Grounding and High Frequency
Interference Protection section of this manual for
the proper procedure on grounding the work clamp
and work piece.
SHIELDING GAS CONNECTION
Obtain the necessary inert shielding gas (usually
argon). Connect the cylinder of gas with the
pressure regulator and flow gage. Install the gas
hose between the regulator and gas inlet (located
on the rear of the welder).
CYLINDER could explode if
damaged.
Keep cylinder upright and
chained to a support.
Keep cylinder away from areas where it could
be damaged.
Never allow the torch to touch the cylinder.
Keep cylinder away from live electrical circuits.
Maximum inlet pressure 150 psi.
A cylinder is loaded by leaning it slightly sideways
and rocking it up on the platform, being careful not
to allow the Under-Storage Cart to roll. Secure the
cylinder in place with the provided chain. Unload by
following these steps in reverse.
ADJUSTABLE FOOT CONTROL CONNECTION
A Adjustable foot control receptacle is provided on
the case front of the welder for connecting a remote
control to the machine.
CONNECTIONS FOR STICK (SMAW) WELDING
A. NEGATIVE CONNECTION B . POSITIVE CONNECTION
STICK ELECTRODE CABLE AND WORK CABLE
CONNECTION
Refer to Field Installed Options in Accessories
Section of this manual for STICK welding
equipment which is available for use with the
inverter machine. An electrode holder with
Twist-Mate cable and Twist-Mate connector are
available separately for use with the inverter
machine.. Turn the Power Switch "OFF". Connect
the Twist-Mate quick connect plug into the
Electrode and turn it clockwise until it is tight. The
work cable and work clamp are factory connected.
