Safety Precautions
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.)
• 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
have double insulation.
• 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.
Use a #8 or larger copper wire connected between the
machine grounding stud and the 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 enti-
tled "Standby Power Connections" as well as the arti-
cle on grounding in the latest National Electrical Code
and the local code.
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 water pipe going into
the ground for at least ten feet and having no insulat-
ed joints, or to the metal framework of a building
which has been effectively grounded.
The National Electrical Code lists a number of alter-
nate means of grounding electrical equipment.
A machine grounding stud marked with the symbol
is provided on the front of the welder.
SPARK ARRESTER
Some federal, state, or local laws may require that
gasoline engines be equipped with exhaust spark
arresters when they are operated in certain locations
where unarrested sparks may present a fire hazard.
The standard muffler included with this welder does
not qualify as a spark arrester. When required by local
regulations, the K894-1 spark arrester must be
installed and properly maintained.
An incorrect arrester may lead to damage to the
engine or adversely affect performance.
------------------------------------------------------------------------
LIFTING
The WELDMARK 225 weighs approximately 397.5
lbs. with a full tank of gasoline. A lift bail is mounted to
the machine and should always be used when lifting
the machine.
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer
’ s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.
