Series Features

  • 01

    The optimal pressure can be set for each welding spot

  • 02

    Their soft touch hardly ever leave dents, and produce little noise

  • 03

    Exhaust air does not come out, so air does not get dirty.

  • 04

    Cycle time can be shortened by synchronized operation with the robot.

  • 05

    Various variations (reduction gear type, KR direct acting type, light weight type) are available for various applications

Reduction gear type X gun

Reduction gear type X gun

Features

  • DGT's proprietary high-rigidity gun with a reduction gear in the spindle
  • Suppressing core misalignment and backlash
  • Maintenance-free without bushing or thrust washer (greasing once every 5 years)
  • Slim and compact gun body
  • Reduction of spare parts by standardization of parts
  • Dust-proof and drip-proof structure improves durability

KR Type Direct acting X gun

KR Type Direct acting X gun

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
