Lincoln Electric Precision TIG 225 AC/DC TIG Welder, 230V Single-Phase, K2533-2

The Lincoln Electric Precision TIG 225 AC/DC TIG welder is a 225-amp inverter machine for TIG and stick welding in fabrication shops, small automotive shops and vocational training. This base model runs on 230 V single-phase power, delivers 5-225 A DC TIG and 5-200 A AC TIG, and uses patented Micro-Start II technology for steadier starts, arc stability and crater fills.

AC frequency adjusts from 20 to 150 Hz and AC balance from 15 to 85% electrode negative. For aluminum welding, AC Auto Balance sets the mix of cleaning and penetration automatically, and it can be bypassed for manual control on thicker material or heavy oxide layers. Arc starts use high frequency, with Lift-Arc available on DC, post-flow gas is adjustable, and the simple interface only asks for mode and polarity before welding.

The TIG pulser (0.1-10 Hz, DC only) limits distortion from excess heat input and helps keep filler deposition and bead appearance consistent. As a stick (SMAW) welder it runs electrodes up to 5/32 in. (4.0 mm), including Fleetweld 5P+ (E6010), and 115 V receptacles can power a water cooler or other tools. The machine carries CSA and CE certifications.
