Lincoln Electric, K3946-2, TIG Welder, 375 A, AC/DC, Inverter/Chopper, Water-Cooled

ADVANCED TECHNOLOGY MADE SIMPLE. A quality weld is always important. Choose a TIG welding machine that meets the demanding quality standards of the aerospace, motorsports, shipbuilding, education and fabrication industries. The Aspect® 375 is the perfect choice for mission critical welds, especially on applications that must stand up to the most rigorous testing requirements.

Features

• AC Wave Shape Control - Enables you to customize the arc for critical aluminum welding requiring: a higher degree of penetration on thicker materials, increased cleaning action in breaking through heavy oxide layers, or narrower arc profile enhancing control around corners and other tight configurations.
• Customization When You need it. - Manage AC frequency, balance and offset to modify arc profile, cleaning action or penetration
• Simplicity When You Want It - Activate Intellistart™ technology to automatically provide for softer starts and minimal distortion on thinner materials and hotter starts required for thicker materials.
• Effortless Arc Control - Extremely fast arc response and stability for the smoothest and most efficient weld possible.
• Optional AC Auto Balance® Technology - Offers simplicity by automatically providing the optimal mix of cleaning and penetration when welding aluminum.
• Ready-Pak ships fully assembled with the CoolArc 47 water cooling system, cart, TIG torch, cable cover, expendables kits, coolant, Foot Amptrol™, regulator and hose kit, and necessary adapters and connectors.
