200BL3 Catalog
* This product is sold as a set. A welding power source, torch, and gas regulator are included.

Key functions

  • Lightweight and compact body that is easy to use on site

  • Stable welding quality

  • Simple and easy-to-use operation


Achieving higher quality welding

Full digital control enables a good arc start and precise welding current setting. This series prevents variations in welding conditions and enables high-quality welding.

Portability for on-site welding

Despite its all-sheet-metal structure and robust body, it weighs only 9 kg. Comes with a metal fitting to prevent it from overturning, making users feel free to bring it to locations for on-site welding.

Usability during on-site welding

Equipped with welding condition storage and reproduction functions (9 channels) as standard. The functions are convenient for frequent on-site welding, enabling users to manage welding conditions for each joint shape or plate thickness, or standardize the setting conditions to ensure stable quality.

Strengths and Features

200BL3 compact body

Compact body designed for on-site welding

The main unit width is kept to 95 mm, making it easy to carry around with one hand. Although this product possesses a robust body with an entirely sheet metal structure, it has achieved a compact and lightweight body weighing only 9 kg. The input voltage range of 170 to 253 V allows a stable operation regardless of the on-site power supply conditions.

Equipped with DC pulse functions as standard

Equipped with DC pulse functions as standard

Enables the setting of 0.5 to 500 Hz. Achieves high-quality welding tailored to the workpieces.

BL3 series equipped with arc spot functions

Equipped with arc spot functions

Enables the digital setting of 0.1 to 5.0 seconds (in 0.1-second increments). Stabilizes the welding quality with a uniform bead appearance and good penetration.

200BL3 operation panel

Easy to operate with an LCD and simple button layout

This product can be operated with a large jog dial and three buttons. The welding condition memory (9 channels) enables storage and reproduction of welding conditions according to the workpiece.


  1. On-site welding: As a data bank to manage welding conditions for each joint shape and plate thickness
  2. Light work: As a notepad to keep track of welding conditions
  3. Production site: For standardizing welding conditions to ensure stable quality
  4. Skill training: As a tool for passing on skills for managing difficult settings for TIG welding
