Key Benefits

• Smooth, proven pure DC welding performance – The machine uses a hand-built pure DC generator with all-copper windings for a smooth, stable arc and better arc control in demanding field work.
• Excellent control for pipe welding – The 5-step current control and fine adjustment let operators dial in a digging arc for root beads or a softer arc for fill and cap passes.
• Multi-process versatility on the jobsite – With Stick, TIG, MIG, Flux-Cored, and gouging capability, this unit can handle a wide range of fabrication, repair, and construction tasks.
• Built-in CC/CV flexibility – The standard built-in CV output contactor helps support wire processes without needing a separate wire feeder module, reducing setup time and downtime.
• Fine heat-input adjustment – CustomArc on the Perkins model provides up to 150 RPM of engine speed adjustment, giving welders extra precision when tuning arc characteristics.
• Long run time for remote work – The 16-gallon fuel tank is designed to extend operating time in the field, which is especially valuable on pipeline and remote construction jobs.
• Cold-weather readiness – A standard on-board block heater helps pre-heat the engine for use in low-temperature environments.
• Reliable diesel durability – The Perkins Tier 4 turbo diesel platform, heavy-duty construction, and Lincoln’s long-established rotating armature/field coil design support dependable daily operation in harsh working conditions.
