Product catalog summary
Overview: The document provides technical specifications and features of the Dialarc® 250 AC/DC Stick Welding Power Source by Miller Electric Mfg. Co., designed for light industrial applications such as production line work, plant maintenance, and vocational school training.
Specifications: The power source operates on single-phase power with rated outputs of 225 A at 29 V for AC and 175 A at 27 V for DC, with duty cycles of 30% and 50% respectively. It features a maximum open-circuit voltage of 70 for AC and 79 for DC.
Features: Key features include single-dial current control for easy weld adjustment, superior performance with 6010 and 7018 electrodes, power factor correction for reduced power demand, and infinite current control for precise weld output. The unit also offers two weld ranges for both AC and DC, a forced-draft cooling fan for extended product life, and optional remote weld output control.
Construction and Reliability: The power source is built with fully varnished magnetic amplifier technology for lower maintenance and reliability. It is warranted for 3 years for parts and labor, with main power rectified parts warranted for 5 years.
Accessories: Available accessories include various stick cable sets, remote current control facilities, remote hand and foot amperage controls, and running gear.
Performance Data: The document includes volt/amp curves and duty cycle charts for both AC and DC welding, illustrating performance across different ranges.
Dimensions and Weight: The unit measures 24-1/4 in (H) x 19 in (W) x 28 in (D) and weighs approximately 360 lb (163 kg) net.
Ordering Information: The document lists stock numbers for different configurations and accessories, along with a section for total quoted price.

Power factor correction is available for lower primary power demand. Industrial, weld output terminal cover. Infinite current control allows precise weld output adjustment; you always get the exact heat you need to produce a better weld. Two weld ranges for both AC and DC welding allow greater control of weld performance for changes in welding conditions. Fully varnished magnetic amplifier technology provides lower maintenance, and outstanding product reliability with fewer moving parts. Forced-draft cooling fan ensures a cooler running product, extending the life of the power source. Optional remote weld output control provides current control without going back to the power source—saves time and effort. Power source is warranted for 3 years, parts and labor. Original main power rectified parts are warranted for 5 years. Quick Specs High output and duty cycle allows unit to handle nearly all of your Stick welding needs.
