Miller SRH-444 Stick Welder # 900751

SRH-444 power source is the reliable favorite of the welding industry because of its history of proven durability. Welders have come to appreciate the SRH's ability to get the job done over a wide range of applications. Electrical amperage control gives operators fine tuning adjustment for a wide range of electrodes. Remote control capability allows operators the same fine tuning capability at an extended distance. High and low output studs offer welders two wide amperage ranges for better resolution and flexibility. Control Circuit overload protection protects main transformer from potential damage and reduces costly repairs. Hot Start used on some Stick (SMAW) machines to make it easier to start difficult-to-start electrodes. Used for arc starting only.
