WELDER OPERATION
WELDER OUTPUT
•Maximum Open Circuit Voltage at 3700 RPM is 80 Volts RMS.
•Duty Cycle is the percentage of time the load is being applied in a 10 minute period. For example, a 60% duty cycle represents 6 minutes of load and 4 minutes of no load in a 10 minute period. Duty Cycle for the WELDMARK 225 is 100%.

AUXILIARY POWER
The WELDMARK 225 can provide up to 9,000 watts of 120/240 volts AC, single phase 60Hz power for continuous use, and up to 10,500 watts of 120/240 volts AC, single phase 60Hz power peak use. The front of the machine includes three receptacles for connecting the AC power plugs; one 50 amp 120/240 volt NEMA
120/240 VOLT DUAL VOLTAGE RECEPTACLE
The 120/240 volt receptacle can supply up to 38 amps of 240 volt power to a two wire circuit, up to 38 amps of 120 volts power from each side of a three wire cir- cuit (up to 76 amps total). Do not connect the 120 volt circuits in parallel. Current sensing for the automatic idle feature is only in one leg of the three wire circuit as shown in the following column.

120 V DUPLEX RECEPTACLES
The 120V auxiliary power receptacles should only be used with three wire grounded type plugs or approved double insulated tools with two wire plugs.
The current rating of any plug used with the system must be at least equal to the current load through the associated receptacle.
MOTOR STARTING
CAUTION
Do not connect any plugs that connect to the power receptacles in parallel.
Start the engine and set the “IDLER” control switch to the desired operating mode. Set the “CONTROL” to
10.Voltage is now correct at the receptacles for auxil- iary power.
Most 1.5 hp AC single phase motors can be started if there is no load on the motor or other load connected to the machine, since the full load current rating of a
1.5hp motor is approximately 20 amperes (10 amperes for 240 volt motors). The motor may be run at full load when plugged into only one side of the duplex receptacle. Larger motors through 2 hp can be run provided the receptacle rating as previously stated is not exceeded. This may necessitate 240V operation only.
WELDMARK 225 Extension Cord Length Recommendations
(Use the shortest length extension cord possible sized per the following table.)
