Lincoln Aspect 230 Ac/Dc TIG Welder (K4340-1)

Sold here as the bare power source, the Lincoln Aspect 230 (model K4340-1) is a lightweight, portable AC/DC TIG machine with built-in high frequency for clean starts on aluminum. Peak output sits at 230A, and Lincoln rates the duty cycle there at 35%.

What it does

Because this listing covers only the power source, a torch, foot control, and cart are each a separate purchase before it can strike an arc. Once wired up, the machine will weld material as thick as 1/4 inch and holds saved settings in memory, so a shop can recall a procedure instead of redialing it. For aluminum, four AC wave shapes are on tap: Soft Square for a controlled puddle, Sine for a quieter arc sound, Square for quicker travel speed, and Triangular when heat needs to stay low on thin stock.

Features worth knowing about

Intellistart eases the start on thin material while still giving enough heat to strike on heavier pieces, and the power supply itself will take anywhere from 120 volts up to 460 volts, cycling at either 50 or 60 Hz, on single-phase or three-phase service without any manual switch. AC Auto Balance keeps the cleaning-versus-penetration mix dialed in on aluminum without operator input, a fan spins up only when cooling is actually needed, and the machine drops into a standby mode after ten minutes sitting idle.

Common questions

Does it come with a torch or cart? No; as the power source alone, a torch, foot pedal, and cart all need to be added. How much does it weigh? Roughly 50 lbs, light enough to carry between bays. Like most welding power sources, this one is labeled under California's Proposition 65 rule.
