Stick Welders - Dialarc® 250 AC/DC
Single-dial infinite current control simplifies and allows precise weld output adjustment; you always get exact heat needed 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.

Forced-draft cooling fan ensures cooler running product, extending life of power source.

Superior 6010 and 7018 Stick welding performance offers wide range of electrode versatility; welds difficult-to-weld materials.

High output and duty cycle allow unit to handle nearly all Stick welding needs.

Optional remote weld output control provides current control without going back to power source - saving time and effort.

Optional Power Factor Correction with Dialarc 250 P for lower primary amperage demand.
