![KR Type Direct acting X gun](https://www.dengenshatoa.co.jp/wordpress/wp-content/uploads/welding-guns-series2-product02.png)
Features
- Our unique high rigidity X-gun, which employs a KR unit in the drive section
- Hight rididity of KR unit makes it possible to bigger throat opening and replace with X gun
- Approach to the welding point is easy because the motion to the welding point is linear rather than rotary.
- Linear motion prevents core misalignment due to electrode wear
