Lincoln U5126-1 (K5126-1) Square Wave TIG 200 TIG Welder Features

• Advanced Features Yet Easy to Use The user interface makes machine setup easy. Available features, such as Pulse, which provides a drumbeat-like rhythm for filler metal deposition, make you become a better TIG welder – faster
• A Great TIG Machine for Aluminum – For a wider or tighter welding bead, users can easily adjust AC Frequency Control. AC Balance can be adjusted to provide more cleaning action on dirty aluminum or to maximize penetration on thick materials.
• TIG and Stick from One Power Source – The multi-process machine can TIG weld when precision and bead appearance are important. Users also have the advantage of stick welding capability for outdoor work or thicker materials.
• Take it Everywhere, Plug in Anywhere.™ – Plug in the Square Wave TIG 200 where you need it – a standard 120V circuit or 230V for maximum output. Portable and convenient to use, only 46 lb (21 kg).
• AC Frequency 60-150 (Hz) – A lower frequency results in a wider bead. A higher frequency results in a more focused bead
• AC Balance 60-90 (%Electrode Negative) – A lower AC Balance (%EN) results in an arc with increased cleaning action. A higher AC Balance (%EN) results in an arc with higher penetration
• Pulse 0.1-20 (Pulses per second) – Lower pulse frequency helps moderate filler metal deposition. A higher pulse frequency helps manage heat input and minimize material distortion
