Common Questions
19 totalWhat is the rated output of the Dialarc 250 AC/DC?
The rated output is 225 A at 29 V for AC and 175 A at 27 V for DC. The AC rated output is at 30% duty cycle for low range and 50% duty cycle for high range. These ratings apply across all power factor correction configurations. (Page 2)
What are the welding amperage ranges available on the Dialarc 250 AC/DC?
Without Power Factor Correction at 60 Hz, the AC low range is 35–165 A and the high range is 105–300 A. The DC low range is 35–155 A and the high range is 90–265 A. These ranges allow greater control of weld performance for changes in welding conditions. (Page 2)
What is the maximum open-circuit voltage for AC and DC modes?
The maximum open-circuit voltage is 70 V for AC and 79 V for DC. These values apply across all power factor correction configurations at both 50 and 60 Hz. (Page 1)
What controls are on the front panel of the Dialarc 250 AC/DC?
The control panel includes an Amperage Adjustment Control, a Range Selector Switch, a Circuit Breaker, and a Power Switch. These four controls allow the operator to set and adjust weld output for both AC and DC modes. (Page 2)
Can I control the amperage remotely without going back to the power source?
Yes, an optional remote weld output control is available that provides current control without returning to the power source, saving time and effort. The RF-10 Remote Current Control Facilities must be installed first, and then either the RHC-3 Remote Hand Amperage Control or the RFC-23A Remote Foot Amperage Control can be used. (Pages 1, 3)
What is the warranty on the Dialarc 250 AC/DC?
The power source is warranted for 3 years, parts and labor. Original main power rectified parts are warranted for 5 years. (Page 1)

Processes Stick (SMAW) Air Carbon Arc (CAC-A) Cutting and Gouging Light Industrial Applications Production Line Work Plant Maintenance Garage/Job Shops Fabrication Vocational School Training Stick Welding Power Source Issued May 2015 • Index No. AD/2.1 Single-dial current control simplifies weld adjustment. Infinite current control allows precise weld output adjustment; you always get the exact heat you need to produce a better weld. High and low ranges for both AC and DC 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. Power source is warranted for 3 years, parts and labor.
