Get the widest operating range in its class (5 to 230 amps) with the durable, professional-grade Precision TIG 225 AC/DC TIG welding machine. Experience enhanced arc starting, optimal arc stability, and accomplish more precise welds and superior crater fills with our patented Micro-Start™ II technology. The convenient built-in 115V auxiliary receptacles enable you to power a water cooler, grinder, or other power tools directly at your workstation for increased productivity. Ideal for small automotive repair shops, fabrication shops, maintenance operations, and vocational training schools requiring versatile, reliable TIG welding performance.
SIMPLE TO USE, EASY TO CUSTOMIZE
Simplicity
Intuitive easy-to-use operator interface - simply select welding mode, set polarity, and begin welding with confidence. When welding aluminum materials, the innovative AC Auto Balance® technology automatically provides the optimal mix of cleaning action and penetration depth for superior weld quality without manual adjustment.
Adjust for Any Welding Situation: Cleaning, Penetration and Pulse
When welding thicker aluminum material requiring increased penetration depth, or when requiring increased cleaning action to break through heavy oxide layers on contaminated surfaces, bypass AC Auto Balance® and adjust manually for full operator control and customization. Enable the advanced TIG pulser feature to minimize material distortion from excessive heat input on thin materials. The precision TIG pulser can also help moderate filler metal deposition for consistent bead appearance and professional-quality results.
Superior Stick Welding Performance
Also offers outstanding stick welding (SMAW) capabilities with exceptional arc performance, including the ability to use up to 5/32 in. (4.0 mm) diameter stick electrodes - even with demanding cellulosic electrodes like Fleetweld® 5P+ (E6010) for pipeline and all-position welding applications.
