SAFETY PRECAUTION
WARNING
ELECTRIC SHOCK can kill.
• Only a qualified electrician should
connect
Controller. Installation should be
made in accordance with the
appropriate National Electrical
Code, the local codes and the infor-
mation in this manual.
• Turn off the input power to the
power source at the disconnect
switch or fuse box before working
on this equipment. Turn off the
input power to any other equipment
connected to the welding system at
the disconnect switch or fuse box
before working on this equipment.
• Do not touch electrically hot parts.
----------------------------------------------------------------------------------------
WELDING VOLTAGE
Wire feed parts are electrically live while welding and
while feeding wire (with Touch Sense feature select-
ed). The electrically live parts are listed below:
Electrode
Wire Drive Motor
Gear Box
Wire Straightener
Welding Cables
CAUTION
• Do not touch electrically live parts or
electrodes with your skin or wet cloth-
ing.
• Insulate yourself from the work and
ground.
• Always wear dry insulating gloves.
MECHANICAL HAZARDS
• Welding fixture or wire feeder will
move during welding or inching. Keep
away from pinch points.
• Electrode reel and drive rolls turn during weld-
ing or inching. Keep gloved hands away from
areas that may catch the glove.

AutoDrive® 19 Controller

LOCATION AND MOUNTING

The AutoDrive® 19 is IP23 rated for use in an outdoor
environment. The AutoDrive® 19 Controller should not
be subjected to falling water during use nor should any
parts of it be submerged in water. Doing so may cause
19
improper operation as well as pose a safety hazard.
The best practice is to keep the controller in a dry, shel-
tered area.
The AutoDrive® 19 Controller should be mounted in
the vertical (upright) position and located where there is
little risk of impacts to the controller.
.

HIGH FREQUENCY PROTECTION

Locate the AutoDrive® 19 controller away from radio
controlled machinery. The normal operation of the
AutoDrive® 19 may adversely affect the operation of
RF controlled equipment, which may result in bodily
injury or damage to the equipment.
CONTROL CABLE CONNECTIONS
GENERAL GUIDELINES
These guidelines apply to all communications
cables including optional DeviceNet and Ethernet
connections.
• Genuine Lincoln control cables should be used
at all times (except as noted otherwise). Lincoln
cables are specifically designed for the communica-
tion and power needs of the Power Wave/
AutoDrive® systems. Most are designed to be con-
nected end to end for ease of operation.
• Always use the shortest cable lengths possible.
DO NOT coil excess cable. It is recommended that
the total length of control cable does not exceed
100ʼ (30.5M). The use of non-standard cables in
excess of 25ʼ (7.5M) can lead to communication
problems (system shutdowns), poor motor accelera-
tion (poor arc starting), and low wire driving force
(wire feeding problems).
• Best results will be obtained when the control
cables are routed separate from the weld cables.
This minimizes the possibility of interference
between the high currents flowing through the weld
cables and the low level signals in the control
cables.
