Auxiliary Power While Welding

It must be noted that the above auxiliary power ratings
are with no welding load. Simultaneous welding and
power loads are permitted by following Table III. The
permissible currents shown assume that current is
being drawn from either the 115V or 230V supply (not
both at the same time). Also, the "Output Control" is
set at "10" for maximum auxiliary power.

Standby Power Connections
The Weldmark 225 is suitable for temporary, standby,
or emergency power using the engine manufacturer's
recommended maintenance schedule.
The Weldmark 225 can be permanently installed as a
standby power unit for 230V-3 wire, single phase 35
ampere service.
WARNING
(Connections must be made by a licensed electri-
cian who can determine how the 115/230V 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.)
1. Install a double pole, double throw switch between
the power company meter and the premises
disconnect.
Switch rating must be the same or greater than
the customer's premises disconnect and service
overcurrent protection.

35amp 230V double pole circuit breaker. Maximum
rated load for the 230V auxiliary is 35 amperes.
Loading above 35 amperes will reduce output
voltage below the allowable -10% of rated
voltage which may damage appliances or other
motor-driven equipment.
