The "Gas Atekun" is a revolutionary welding tool designed to prevent oxidation that occurs on the backside during welding. When welding without a back seal, oxidation can cause black marks on the reverse side. Traditional back seal tools used to prevent this have issues such as difficulty in sealing due to size and shape, and the hassle of slag removal. This product allows anyone to achieve a clean finish simply by blowing shielding gas directly onto the backside of the weld. 【Sales Contents & Price】 ■ Gas Atekun Straight: 1 unit ■ Gas Atekun 60°: 1 unit ■ Gas Atekun 90°: 1 unit ■ Regulator: 1 unit ■ Connection Hose 10m: 1 unit ■ Connection Hose 2m: 1 unit ■ Instructional Video: 1 piece Price: 160,000 yen (excluding tax) 【Features】 ■ The tip is made of copper, which is less likely to damage the product ■ The body and pipe are made of corrosion-resistant titanium ■ Available in three types: Straight, 60°, and 90° *For more details, please refer to the PDF document or feel free to contact us.
