INSTALLATION FOR STAND-BY USE
Precautions must be taken to prevent
electrical back feeding into utility
systems. This requires isolation of
the electrical system. To isolate the
electrical system, perform the following
procedures:
1.
Turn off the main electrical system
switch prior to connecting the
welder / generators.
2.
In accordance with national and
local standards, a double throw
transfer switch must be installed in
the system.
Always shut off
main power prior to
temporary connection of the welder /
generators to a building electrical
system.
Installation of the
welder / generator
as a backup electrical source must be
performed by a qualified (licensed or
certified) electrical technician.

WELDING LEAD ASSEMBLIES
Welding leads assemblies are not
included with all units. Use copper
welding cables in the size specified in
Table 3.
GROUND CLAMP (SEE FIGURE 1)
1.
Strip 1/2 inch of insulation from the
end of one of the welding cables.
2.
Loosen hex nuts on work clamp.
3.
Insert the end of the welding cable
through clamp handle and slide the
bare wire under the clamp block.
4.
Tighten the hex nuts, securing the
cable in place.
ELECTRODE HOLDER (SEE FIGURE 2)
1.
Strip 1/2 inch of insulation from the
end of the other welding cable.
Slide the bare wire into the wire
sleeve.
2.
Loosen the phillips head screw
a few turns. Do not remove it
completely. Pull the insulated
handle off of the electrode holder,
and slide it over the welding cable.
