How do you tig weld aluminum
WebAluminum has a low melting point -- 1200° F compared to 2600° F to 2700° F for steel. Because of this low melting point, many operators think they only need light duty equipment to weld the aluminum. But, the thermal conductivity of aluminum is five times that of steel, which means that the heat dissipates very quickly. WebAluminum tig requires AC (most of the time). AC welding needs high frequency to start and maintain the arc (every time the arc crosses zero and extinguishes, it's restarting). HF needs a foot pedal to know when to go. It might be possible to weld aluminum with scratch start, on DC, without HF, but I wouldn't do it on a professional application.
