Lincoln MAXsa 22 Feed Head (U2370-2) is a heavy-duty submerged arc wire feeder designed for hard automation and semi-automatic SAW applications. It delivers accurate, high-traction feeding of large-diameter submerged arc wire — up to 7/32 in. (5.6 mm) — with a top speed of up to 500 ipm. This is a Lincoln Electric factory demo unit, inspected and certified before sale.
Designed specifically for hard automation applications, the MAXsa 22 Feed Head delivers accurate wire feeding of large-diameter submerged arc wires. Based on Lincoln's proven gearbox and cast aluminum feedplate, the MAXsa 22 features a 40VDC permanent magnet, high-torque motor that delivers substantial traction to push up to 7/32 in. (5.6 mm) diameter solid wire. A top speed of up to 500 ipm (12.7 m/min) can be achieved by changing the gear ratio.

This MAXsa 22 Feed Head (U2370-2) is a Lincoln Electric factory demo unit — used in controlled demonstration or trade show environments and returned to Lincoln Electric for inspection and certification prior to sale. It has not been run in a production environment. Lincoln Electric factory technicians verify all demo units meet new-machine performance standards before they are offered for resale through authorized dealers like WeldingMart.
- Factory-inspected and certified by Lincoln Electric technicians
- Demonstration use only — not a field or production-operated unit
- Significant savings vs. new retail on a high-value automation component
- Ships from WeldingMart with full packaging
- WeldingMart is an Authorized Lincoln Electric Dealer
- Automated submerged arc welding (SAW) — designed for hard automation fixtures on heavy fabrication, pressure vessel, and structural beam work
- Tandem and Twinarc SAW — supports multiple arc configurations for high-deposition-rate applications
- Heavy structural and pressure vessel fabrication — handles large-diameter wire required for thick base metal joints
- Shipbuilding and heavy equipment manufacturing — commonly used in high-volume, high-deposition environments where consistent bead quality is critical
The MAXsa 22 is designed for large-diameter submerged arc wires, capable of feeding up to 7/32 in. (5.6 mm) solid wire. Gear ratio conversion kits can be used to optimize feed speed for different wire diameters and deposition rate targets.
Yes. The MAXsa 22 supports single, tandem, Twinarc, and multiple arc setups, making it one of the most flexible feed heads in Lincoln's submerged arc lineup.
The MAXsa 22 Feed Head is designed to work with Lincoln's MAXsa controller series. Contact WeldingMart at 920-659-6177 to confirm controller compatibility for your specific automation setup.
Lincoln Electric demo units are used at trade shows, training centers, and customer demonstrations — never run in a production environment. After use, they are returned to the factory, inspected by Lincoln technicians, and certified to meet new-unit performance standards before sale through Authorized Dealers.
