#4 LOTOS TIG200ACDC 200A Aluminum Tig Welder
This TIG welding uses an electric arc to weld metals and plastics together and is typically used for spot welding, seam welding, and plastic components. A TIG torch is a hand-held device that transfers an electrical arc from a non-consumable electrode, usually tungsten, to the welded material. The arc melts the base metal, creating a molten puddle that mixes with filler material (metal).

The TIG200ACDC is a 2.0Ah Li-ion rechargeable battery pack (Tough pack). It can deliver 200A continuously for 4.5 hours; it can be connected to a power supply with a rated output of 200A. However, this welder includes two channels (a TIG channel and a stick/arc channel). Its two channels have a digital power meter for accurate power monitoring, allowing users to adjust welding speed and current for optimal results.
The TIG200ACDC has 3 buttons for the TIG channel; ON/OFF/AUTO, which allows the user to choose the right position of the electrode (TIG electrode and stick electrode), the welding temperature (400-600°F), and arc length.
Machine IncludesHowever, the TIG200ACDC also includes 5 switches to control the DC stick channel; AUTO, ON, T1, T2, and T3, with a maximum output of 15A. With this high power, TIG200ACDC is suitable for welding aluminum, stainless steel, and other materials with high strength and toughness.

FAQs
Can you TIG weld thin aluminum?
Yes, you can TIG weld thin aluminum. However, you must use a smaller tungsten electrode and a higher welding current.
What is the thinnest metal you can TIG weld?
The thinnest metal you can TIG weld is typically about 0.020 inches thick. However, it’s important to note that the thinner the metal, the more difficult it is to weld properly.
What is the minimum thickness for TIG welding?
The minimum thickness for TIG welding is about 1.5mm.
How do you weld super thin aluminum?
Welding aluminum is possible with a TIG welder but requires a higher heat input and a slower welding speed than welding steel. The weld puddle will be more fluid, and the weld bead will be narrower than welding steel.
