AUXILIARY POWER WHILE WELDING
Simultaneous welding and power loads are permitted
by following Table I. The permissible currents shown
assume that current is being drawn from either the
120V or 240V supply (not both at the same time).
Also, the "Output Control" is set at "10" for maximum
auxiliary power.

Not to exceed 40A per 120VAC branch circuit when
splitting the 240 VAC output.
STANDBY POWER CONNECTIONS
The WELDMARK 225 is suitable for temporary, stand-
by, or emergency power using the engine manufactur-
er's recommended maintenance schedule.
The WELDMARK 225 can be permanently installed as
a standby power unit for 240V-3 wire, single phase 38
ampere service.
WARNING
(Connections must be made by a licensed electri-
cian who can determine how the 120/240V power
can be adapted to the particular installation and
comply with all applicable electrical codes.) The
following information can be used as a guide by
the electrician for most applications (refer also to
the connection diagram shown in Figure 1.)
