The AC/DC TIG 200P welder is a powerful aluminum TIG welding machine that offers welding with TIG AC Square/Triangular/Pulse Square/Pulse Triangular/DC Pulse/DC/STICK methods. It can be used for welding various metals, including aluminum, steel, stainless steel, carbon steel, and copper.
The technology improves arc striking speed, welding efficiency, and results, while the pulse, square, and triangular waveform functions prevent material burning, minimize distortion, and improve bead appearance. The digital control system makes the machine reliable and stable, and the large LED display allows for easy parameter adjustment.
The TIG200P AC DC Pulse Tig Aluminum Welder is lightweight and compact at only 12 kg (26.5lb). Plus, included safety features like VRD, over-current, over-voltage, overload, and over-temperature protection make it user-friendly and reliable.
Moreover, you can choose between 2T/4T/Spot welding TIG torch control and foot pedal remote control methods for a more versatile welding experience. This is a great choice for pro welders!

FAQ
Where is it shipped from?
From local warehouses in the US and Canada, with fast and free delivery.
Can it weld aluminum?
Yes. TIG200P ACDC supports AC TIG mode designed for aluminum. It handles thin sheets (as low as 0.9 mm) and thick plates up to 6 mm with stable arc and clean beads.
What types of metals can it weld?
Aluminum, stainless steel, mild steel, copper, and more. Use AC TIG for aluminum and DC TIG for other metals.
What’s the difference between AC and DC TIG?
AC TIG is for aluminum and magnesium; DC TIG is for steel, stainless, and copper. The AC wave cleans the oxide layer on aluminum for a smooth, shiny weld.
What gas should I use for TIG welding?
Use 100% Argon gas. For aluminum, pure Argon at 15–20 CFH works best. For steel or stainless, the same gas can be used.
What voltage does it work on?
It’s dual voltage 110V/220V.
What is the maximum output difference between 110V and 220V?
Output power is capped when running on 110V to prevent standard home breakers from tripping. For maximum performance, use a 220V outlet.
110V Max Output ：TIG Welding 120 Amps | MMA/Stick Welding 110 Amps
220V Max Output：TIG Welding 200 Amps | MMA/Stick Welding 160 Amps
What kind of tungsten should I use?
For aluminum (AC): 2% Zirconiated (White) or 2% Lanthanated (Blue).
For steel (DC): 2% Thoriated (Red) or 2% Lanthanated (Blue).
How long is the warranty?
5 Years. A 5-year warranty applies to the core components of the unit, effective from the date of purchase by the consumer. Wear parts and structural components are not covered under the warranty.
Does it come with a foot pedal?
Not included in the base unit — but you can add it directly via the "Welder + Foot Pedal" option above.
Does it have Pulse TIG? What is it for?
Yes. Pulse TIG lets you control heat input and arc stability — perfect for thin metals and precise welds. It improves appearance and reduces burn-through.
