When in the TOUCH START TIG mode and when a
Amptrol is connected to the 6-pin Connector the OUT-
PUT dial is used to set the maximum current range of
the CURRENT CONTROL of the Amptrol.
The ARC CONTROL is not active in the TIG mode.
The DX300e (CE) can be used in a wide variety of DC
TIG welding applications. In general the 'Touch Start'
feature allows contamination free starting without the
use of a Hi-frequency unit. If desired, the K930-2 TIG
Module can be used with the DX300e (CE). The set-
tings are for reference.
DX300e (CE) settings when using the K930-2 TIG
Module with an Amptrol or Arc Start Switch:
• Set the MODE Switch to the TOUCH START TIG
setting.
• Set the "IDLER" Switch to the "AUTO" position.
• Set the "WELDING TERMINALS" switch to the
"REMOTELY CONTROLLED" position. This will keep
the "Solid State" contactor open and provide a "cold"
electrode until the Amptrol or Arc Start Switch is
pressed.
When using the TIG Module, the OUTPUT control on
the DX300e (CE) is used to set the maximum range of
the CURRENT CONTROL on the TIG module or an
Amptrol if connected to the TIG Module. (See Table
B.2.)
WIRE WELDING-CV
Connect a wire feeder to the DX300e (CE) according to
the instructions in INSTALLATION INSTRUCTIONS
Section.
The DX300e (CE) in the CV-WIRE mode, permits it to
be used with a broad range of flux cored wire
(Innershield and Outershield) electrodes and solid wires
for MIG welding (gas metal arc welding). Welding can
be finely tuned using the ARC CONTROL. Turning the
ARC CONTROL clockwise from –10 (soft) to +10 (crisp)
changes the arc from soft and washed-in to crisp and
narrow. It acts as an inductance/pinch control. The
proper setting depends on the procedure and operator
preference. Start with the dial set at 0.

OPERATION
For any electrodes the procedures should be kept
within the rating of the machine. For additional elec-
trode information see WWW.Lincolnelectric.com.
ARC GOUGING
The DX300e (CE) can be used for limited arc gouging.
For optimal performance, set the MODE switch to CC-
STICK and the ARC CONTROL to +10.
Set the OUTPUT CONTROL knob to adjust output
current to the desired level for the gouging electrode
being used according to the ratings in the following
Table B.3.

AUXILIARY POWER:
Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
regardless of the welding control settings providing no
welding current is being drawn.
Simultaneous Welding and Auxiliary Power Loads
While welding, the amount of 3-phase Auxiliary power
available is reduced. (See table A.4)
