K5622-1 - Lincoln Elevate SLi Cordless Stick/TIG Welder with Rolling Case

Revolutionary Cordless Welding Technology

The Lincoln Electric Elevate™ SLi Battery Powered Welder (K5622-1) represents a significant leap forward in portable welding technology. Designed for professionals who demand performance in the most remote and challenging environments, this machine eliminates the tether of power cords and the bulk of portable generators. At its core is a cutting-edge Lithium Iron Phosphate (LiFePO4) battery, chosen for its superior safety profile, long cycle life, and consistent power delivery. Unlike standard lithium-ion batteries, the LiFePO4 system provides stable thermal performance and rapid charging capabilities, reaching a full charge in approximately one hour using 120V input power.

Industrial Performance in a Compact Package

Despite weighing only 33 lbs (15 kg), the Elevate SLi does not compromise on power. It delivers a robust output range of 20-145 Amps for Stick welding and 4-145 Amps for TIG welding. Utilizing Lincoln Electric’s proven Chopper Technology®, the machine ensures an extremely smooth arc with low spatter and excellent bead appearance. Operators can fine-tune their welds with advanced features typically found on larger shop machines, including adjustable Arc Force to control penetration profiles and Hot Start for reliable arc strikes. The unit is capable of running essential electrodes such as E6010 for cellulosic applications and E7018 for structural repairs, handling diameters up to 5/32 inch (4.0 mm).

Ultimate Mobility with the Rolling Case Package

The K5622-1 package is specifically curated for the mobile welder. It includes the Heavy-Duty Rolling Carrying Case (K5548-1), which transforms the unit into a go-anywhere welding station. This case is engineered to withstand harsh job site conditions, featuring a water-resistant silicone gasket, heavy-duty locking latches, and an impact-resistant shell. With a telescoping handle and 6-inch all-terrain wheels, transporting the welder, cables, and accessories across gravel, dirt, or concrete is effortless. The case interior is organized with an accessory tray to keep your electrode holder, work clamp, and cables secure and ready for deployment.

Hybrid Power Flexibility

Versatility is key with the Elevate SLi. While it excels as a cordless unit, it also features hybrid functionality. When access to power is available, the machine can be plugged into a standard 120V outlet to charge the battery while simultaneously welding. This ensures that downtime is minimized and productivity remains high, regardless of the power situation on site.
