Base plate on, and communicated with the lower end of the conductive body of rod.
Further, the powder feeding mouth of powder input channel is located at the top board of water collar, and its meal outlet is arranged on water collar
Base plate.Powder input channel thoroughly solve material by performance impact can not into silk and tubular filament by filler than being restricted；Powder feeding material
Material can be according to design requirement from metal or the powder such as nonmetallic.
Further, the meal outlet goes out the base plate that powder mouth is removably mounted at water collar.Prevent because splash is blocked
Meal outlet, influences powder.
Further, the water inlet and delivery port of water collar can be effectively protected the connection safety of water pipe in top board
And reliability, prevent from overheating caused loosen or softening.
Further, the conductive body of rod is made of copper.Copper conductive body of rod conduction is good, heat transfer is fast.
Further, the first internal thread is provided with conductive body of rod lower end, is easy to the installation of ignition tip.
Further, the lower end of the conductive body of rod is provided with the second internal thread for installing gas shield cover, according to requiring different installations
Corresponding protective cover.Splashing is effectively improved and reduced, is caused while effectively reducing oxygen uptake, the suction nitrogen of metal bath before curing etc.
Material property change.
Further, the upper end periphery of the conductive body of rod is provided with perpendicular fastening end face, and fastening end face is to be formed from steel
's.Because the self-strength of steel is much larger than copper material, connect then more reliable using steel part.
Compared with prior art, the beneficial effects of the utility model are：
1st, improved welding gun described in the utility model effectively improves electric conductivity by water collar, solves ignition tip because crossing heated filament
Button loosens, and causes resistance to increase, welding current, spread of voltage；Ignition tip is solved because overheat wearability declines to a great extent, it is conductive
Nozzle aperture easily becomes big and produces irregular circular hole, and arc center floats, and directly contributes welding current, spread of voltage, and welding
There is the defect of various uncertainties in surface.Extend the service life of ignition tip, reduce rifle mouth and splash knot.
2nd, improved welding gun described in the utility model, for the characteristic of the excessive heat energy in molten bath produced in welding process,
Employ directly to molten bath powder feeding, one effectively reduces the shrinkage stress that welding is produced, secondly making many original lumbering technologies
The combination of materials that can not be realized, becomes easy, can facilitate by this method and effectively create many new composites.
