Case Dimensions Series 150 -- 6.5" W x 8.5" H x 7" D
(See Series 150 Illustration)
Series 150B -- 6.5" W x 8.5" H x 9" D

(See Series 150B Illustration)
Series 200 -- 6.5" W x 9.5" H x 10" D

(See Series 200 Illustration)
Series 250 -- 7.5" W x 9.5" H x 9" D
(See Series 250 Illustration)
(Clear space clearance requirement -- including pulley, terminals, and mounting lugs)
Typical Voltage Output @ Full Power w/Arc Established 20-26V Ultra High Frequency DC (Typically 18,000-21,000 pulses/controlled wave form transitions per second)
Typical Voltage Output @ Full Power w/NO Arc Established 68-74V Ultra High Frequency DC (Typically 18,000-21,000 pulses/controlled wave form transitions per second)
Min. Power Generator Shaft Speed for Maximum Output Power Approximately 6,500 RPM (Higher shaft speeds up to approximately 16,000 rpm - have no detrimental effect on welding performance)
Typical Min. Engine Speed for Max. Output Power Approximately 2,400 RPM (Assumes typical engine drive pulley to Power Generator pulley ratio of approximately 2.5:1)
Direction of Rotation Series 150 -- Clockwise Rotation

Series 150B -- Bi-directional Rotation
(Clockwise Typical -- Hi-Efficiency Clockwise Option Available)

Series 200 -- Bi-directional Rotation
(Clockwise Typical)

Series 250 -- Bi-directional Rotation
(Clockwise Typical)

Series 150B, 200 & 250 NOTE
When operating a 150B, 200 or 250 series Generator in CCW rotation mode, a thread-locking chemical adhesive should be used to insure Power Generator Drive Shaft Nut to Drive Shaft fastener connection integrity.

Optionally, for high vibration applications, an anaerobic stud/bearing fixing adhesive can also be used to insure secure and continuous, Drive Pulley to Cooling Fan and Drive Pulley to Power Generator Drive Shaft Nut contact.
System Cooling High Efficiency Forced Air  
Expected Minimum Time Before Moving Component Failure 50,000 hours (rotating - welding load) NOTE:
50,000 hours = 2,083 twenty-four hour days (5.7 years of continuous operation)
Periodic Maintenance Requirement None NOTE:
Cleaning (with water and/or compressed air) may be required if operating in very dirty conditions, or if chemical contamination occurs.
DC Power Required (When Welding) 12 volts -- 7 amps. maximum (2 to 4 amps at average welding power settings in 12V electrical system)
DC Power Required (When NOT Welding) 12 volts -- .05 amps.
Control Circuit Protection Internal Fuses (2) (2 amp & 10 amp)
Welding Controls Internal, Solid State OR

External, Solid State
(Built into electrode holder/welding cable assembly)

(Various panel mount type control options)
Accessory Control Circuits

External Device Control Outputs --> Two Standard

(more control outputs can be provided)

Control outputs to control up to 3 separate ASC Series speed controls, and for up to 6 separate WC.12S Slave Power Control Modules.

(additional control outputs can be provided as an extra cost option)
