Inverter DC TIG Welding/ Air Plasma Cutting Machine



image alt


* In addition to this product (welding power source), a torch and gas regulator are required for welding.

Key functions

  • This three-in-one machine for TIG welding, manual welding, and air plasma cutting increases operation rates

  • Versatile waveform control tailored to applications

  • Allows quick switching between cutting and welding

  • Compact and lightweight machine ideal for on-site welding


Concerns about mediocre performance of a multi-purpose machine

In addition to TIG welding, this product supports DC manual welding. It is equipped with versatile waveform control, and possesses sufficient functionality even as a machine specialized for welding.

Concerns about the initial investment for a multi-purpose machine

This product is less-expensive than purchasing a welding machine and cutting machine separately. It requires a storage space for only one unit.

Concerns about the usability of a multi-purpose machine

Customers can use the cables and torches they are accustomed to using.

Strengths and Features

Three-in-one machine applicable in various situations

Three-in-one machine applicable in various situations

TRC can be used as a TIG welding machine, a DC manual welder, and an air plasma cutting machine. Users can switch functions between cutting and welding while the cables are connected. Equipment expenses can be reduced compared to cases where machines are purchased separately. The storage space can also be saved.

High-performance and stable arc

High-performance and stable arc

Arc convergence and stability have been improved by the control that is 1.6 times faster than conventional inverter machines. A stable arc performance can be achieved from 4 A to the rated current. Furthermore, by adopting a new circuit, the startup speed has been approximately doubled, enabling more efficient welding.

Versatile waveform control that can be selected according to the application

Versatile waveform control that can be selected according to the application

Equipped with various welding waveforms for middle pulse control (effective for thin plate welding) and low pulse control (optimal for medium to thick plate welding) as well as initial current control and other control for uniform welding. Settings can be performed on the front panel.

Air plasma cutting can be applied to plates with thicknesses ranging from 0.1 to 35 mm.

Air plasma cutting can be applied to plates with thicknesses ranging from 0.1 to 35 mm.

Capable of cutting thin to medium plates (contact and non-contact) with thicknesses ranging from 0.1 to 35mm. The unit is compact and lightweight, making it ideal for on-site welding.
