Advantages of 200A Inverter Dual TIG Welder

Dual-Process TIG/MMA Versatility for Specialty Fabrication

As a TIG/MMA alloy welding machine, its integrated dual welding modes eliminate the need for multiple equipment for different welding tasks, greatly improving the equipment utilization rate of specialty fabrication enterprises. TIG mode is optimized for precision welding of non-ferrous metals and thin sheets, while MMA mode meets the basic welding needs of structural parts, realizing one machine for multiple professional uses.

Precision Arc Control for Specialty Alloy Materials

The microprocessor-controlled arc system and adjustable pulse TIG function enable precise control of weld bead size and shape, a critical feature for welding aluminium, titanium and nickel-based superalloys. The inert gas shielding in TIG mode avoids oxidation and porosity of non-ferrous metals, maintaining the original material properties such as conductivity and corrosion resistance— the core demand for alloy processing businesses.

Advanced HF Striking & Welding Process Customization

Equipped with HF arc start technology, the welder achieves arc ignition without electrode contact, avoiding scratch marks on the surface of precision workpieces and ensuring the aesthetic of high-end fabrication products. The customizable welding time, interval time and gas blowing time allow users to adjust the welding process according to different materials and thicknesses, meeting the personalized precision welding demands of specialty manufacturing users.

Comprehensive Protection & Professional Accessory Compatibility

Built-in thermostatic, overcurrent, overvoltage and undervoltage protections ensure the safety of the welder and workpieces in long-term precision fabrication. The remote control connector enables flexible operation for large workpieces, while the complete TIG welding accessories (including welding torch, gas regulator and ground clamp) provide a one-stop solution for professional TIG welding, reducing the accessory matching cost for enterprises.

Uses of 200A Inverter Dual TIG Welder

Non-Ferrous Metal Alloy Welding

The top choice for aerospace, automotive and marine fabrication enterprises, it is used to weld aluminium, copper and magnesium alloy parts for aircraft components, automotive engine parts and marine equipment. Its precise arc control ensures perfect welding for thin non-ferrous sheets without burn-through, maintaining the material’s mechanical and physical properties.

Stainless Steel Precision Fabrication

Ideal for food, pharmaceutical and chemical industry equipment manufacturers, it is applied in the welding of austenitic/ferritic stainless steel processing equipment, medical devices and decorative stainless steel products. The smooth and clean welds are easy to polish and sanitize, meeting the strict hygiene and corrosion-resistance standards of these industries— a key benefit of this precision dual-process welder for non-ferrous metal fabrication.

Thin Sheet Metal Professional Welding

Suitable for electronic enclosure manufacturing and automotive panel repair teams, it is used to weld 0.5mm+ thin gauge ferrous and non-ferrous sheets. The adjustable pulsed current prevents warping, distortion and burn-through, the common problems of thin sheet welding, ensuring the precision and flatness of thin-walled components.

On-Site Specialty Alloy Repair

Used by industrial machinery maintenance teams and power plant repair teams for the on-site precision repair of specialty alloy components such as power plant turbine blades and oil/gas downhole parts. Its portability and precise welding performance ensure minimal damage to surrounding materials, with high accuracy for repairing delicate high-quality alloy components in tight industrial spaces.
