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.

TABLE III

SIMULTANEOUS WELDING AND POWER

Output Selector	Permissible Power	Permissible Auxiliary

*Each duplex receptacle on CSA machines is limited to 20 Amps.

**Not to exceed 35A per 115VAC branch curcuit when splitting the 230 VAC output.

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.

2.Take necessary steps to assure load is limited to the capacity of the Weldmark 225 by installing a

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.

3.Install a 50 amp 115/230V plug (NEMA type 14-50) to the Double Pole Circuit Breaker using No. 8,

4 conductor cable of the desired length. (The

50 amp 115/230V plug is available in the optional plug kit.)

4.Plug this cable into the 50 amp 115/230V receptacle on the Weldmark 225 case front.
