Lincoln Electric AC225 K1170 is a 230 V AC stick welder for home workshops, farm repairs, maintenance and light fabrication. The K1170 configuration is distinct from the 220 V, 50 Hz K1290 version described in the same manufacturer sheet.
Key Features and Benefits
- A 40–225 A current selector supports the documented K1170 welding range.
- The AC output is intended for suitable stick electrodes.
- An input cable with a NEMA 6-50P plug is supplied for K1170.
- Included electrode and work connections provide the documented welding cables.
