High -power high fusion penetration TIG welder

The utility model relates to the field of welding technique, especially, relate to a high -power high fusion penetration TIG welder. This TIG welder includes the main rifle body, the rifle body, insulator, tungsten extremely press from both sides and the baffle isotructure down. The utility model discloses a high -power high fusion penetration TIG welder leads to electromagnetic force that overcurrent formed to the dual compression of electric arc compression and gaseous weak compression to electric arc, has reduced the diffusion angle of electric arc, has improved the energy density of electric arc to improved the fusion penetration penetration capacity of electric arc, realized that stable high fusion penetration welds. 本实用新型涉及焊接技术领域，尤其涉及种大功率高熔深TIG焊枪。该TIG焊枪包括主枪体、下枪体、绝缘体、钨极夹以及导流体等结构。本实用新型公开的大功率高熔深TIG焊枪通过大电流形成的电磁力对电弧压缩以及气体对电弧的弱压缩的双重压缩，减小了电弧的扩散角，提高了电弧的能量密度，从而提高了电弧的熔深穿透能力，实现了稳定的高熔深熔透焊。
