Lincoln Electric K1170 Arc Welder 225A 230V

Product Description

The LINCOLN ELECTRIC K1170 is a single-phase AC arc welder rated at 225 amps, designed for stick welding applications in both residential and light commercial settings. It draws 230 volts of AC input current and delivers a smooth, consistent arc suited to a wide range of mild steel welding tasks. At a 20 percent duty cycle at 225 amps, this unit handles intermittent welding work typical of farm, shop, and light fabrication environments. Weighing 106 pounds and measuring 17 inches wide by 24.5 inches high, it is a floor-standing transformer-based welder built for straightforward, no-frills operation. Licensed welders and experienced trades professionals are the primary installers and operators.

The K1170 is well suited to single-phase 230-volt service found in residential garages, farm shops, and light industrial bays. It is intended for shielded metal arc welding (SMAW) using coated stick electrodes on mild steel. The 20 percent duty cycle at full output makes it appropriate for short bead work, tack welding, and repair jobs rather than continuous production welding. Its straightforward controls and smooth arc characteristic make it accessible to operators with varying skill levels working in field or shop environments.

Key Features

• 225-amp output at 20 percent duty cycle supports a broad range of stick electrode sizes

Compatibility

Designed for use with standard coated stick electrodes on single-phase 230-volt AC power supply circuits typical of residential and light commercial installations.

Installation Notes

Installation and operation should be performed by a qualified electrician or certified welder familiar with NFPA 70 (NEC) requirements for welding equipment circuits. Verify that the supply circuit is properly sized for 230-volt single-phase service before connecting. Always shut off and lock out the power supply before making any input wiring connections. Operate in a well-ventilated area and follow all applicable safety guidelines for arc welding, including proper eye protection and grounding of the work piece.
