The Vantage 322 delivers exceptional compact versatility with up to 400 amps (IEC rated at 300 amps) of welding current to tackle numerous welding and carbon arc gouging applications. Operators can select from five basic process modes including CC-Stick, Downhill Pipe, DC Touch Start TIG, CV-Wire, or Arc Gouging mode, which maximizes output for up to 5/16 in. (8.0 mm) carbon rods. This multi-functional machine also provides impressive generator output with up to 11 kW of continuous three-phase power to run industrial tools such as plasma cutters, pumps, or inverter welders, making it an all-in-one solution for diverse jobsite requirements.
Built with patented Chopper Technology, the Vantage 322 delivers premium arc performance with minimized spatter for stick or pipe welding as well as enhanced gouging performance that prevents the engine from stalling, resulting in smooth material removal. The unit is engineered for reliable operations with field-proven ruggedness and durability to meet the most challenging job site needs and harshest environments. Powered by a 22 hp, naturally aspirated Kubota diesel engine, the Vantage 322 runs smooth and quiet while meeting EPA Tier 4 Final compliance standards. The innovative service access features include a lockable and removable sliding access door to service the engine and internal components, a battery drawer on front of machine for quick access, and a top-mounted radiator cover that provides convenient maintenance access. With a large 20 US gal. (75.7 L) fuel tank compared to smaller 11 US gal. (41.6 L) tanks in competitive machines, operators can run longer between fill-ups, maximizing productivity and reducing downtime on demanding job sites.

The Vantage 322 Welder/Generator (Kubota) supports Stick (SMAW) and TIG (GTAW) welding as standard processes. Many engine-driven models in this family also support MIG (GMAW) and flux-core (FCAW) welding when paired with an optional wire feeder. Check the spec sheet for the exact output range and recommended wire feeder compatibility.
Yes. Lincoln Electric engine-driven welders in this class include AC generator power — typically 120V and 240V auxiliary power outlets — making them ideal for jobsite use where power tools, lights, or other equipment need to run alongside welding operations. Refer to the spec sheet for exact generator wattage.
Lincoln engine drives in this class are available with Kohler, Kubota, or Perkins diesel/gasoline engines depending on the specific model variant. The engine brand and displacement is listed on the product label and in the owner's manual. Contact WeldingMart if you need to confirm the exact engine for a specific unit.
Duty cycle varies by amperage setting. At maximum rated output the duty cycle is typically 100% — engine drives are designed for continuous, all-day operation in demanding field environments. Refer to the spec sheet for the duty cycle curve at specific amperage levels.
Yes — this is a factory demo or low-hour unit directly from Lincoln Electric. Units may show light cosmetic marks from display use but are mechanically sound. Each unit includes any applicable remaining Lincoln Electric warranty. Contact WeldingMart for warranty status on the specific unit number.
Factory demo engine drives typically include the base machine and standard accessories as specified by Lincoln Electric. Consumables (electrodes, gas cylinders) are not included. See the product listing details or contact WeldingMart to confirm what is included with your specific unit.
