WELDING OUTPUT CABLES

With the engine off, connect the electrode and work cables to the
terminals provided. These connections should be checked
periodically and tightened if necessary.
Listed in Table A.2 are copper cable sizes recommended for the
rated current and duty cycle. Lengths stipulated are the distance
from the welder to work and back to the welder again. Cable sizes
are increased for greater lengths primarily for the purpose of
minimizing cable voltage drop.

MACHINE GROUNDING

Because this portable engine driven welder creates its own power,
it is not necessary to connect its frame to an earth ground, unless
the machine is connected to premises wiring (home, shop, etc.).
WARNING
To prevent dangerous electric shock, other equipment to
which this engine driven welder supplies power must:
• Be grounded to the frame of the welder using a
grounded type plug or be double insulated.
• Do not ground the machine to a pipe that carries
explosive or combustible material.
When this welder is mounted on a truck or trailer, its frame must
be securely connected to the metal frame of the vehicle. When
this engine driven welder is connected to premises wiring such as
that in a home or shop, its frame must be connected to the system
earth ground. See further connection instructions in the section
entitled "Standby Power Connections" as well as
the article on grounding in the latest National Electrical Code and
the local codes.
In general, if the machine is to be grounded, it should be
connected with a #8 or larger copper wire to a solid earth ground
such as a metal ground stake going into the ground for at least 10
Feet or to the metal framework of a building which has been
effectively grounded.
The National Electric Code lists a number of alternate means of
grounding electrical equipment. A machine grounding stud
marked with the symbol is provided on the front of the welder.
