Fiber tube.
Preferably, the material that the main changeover mechanism, the water inlet pipe and the outlet pipe use is copper alloy, because of copper
Alloy has excellent thermal conductivity, electric conductivity and corrosion resistance.
The beneficial effects of the utility model are:
(1) cooling body is arranged on the outside of protection tracheae in the utility model, takes away pipette tips by cooling water and is transmitted to main turn
Heat on connection mechanism, quality problems caused by avoiding welding gun from stopping welding halfway due to overheat, extends the activity duration of welding gun, this
Protection tracheae in utility model is flat tube, increases the contact area with water inlet pipe and outlet pipe, improves cooling effect.
(2) pipette tips in the utility model are threadedly coupled with main adapter, and the body of a gun is bolted with main adapter, are not needed
Excessive repacking is carried out to former torch body, and dismounts convenience, also avoids being equipped with the damage of former welding gun compared to remanufacturing
The body of a gun of water cooled pipeline, not only cost of manufacture is lower for the utility model, and the scope of application is wider.
(3) size of switching part is little in the utility model, slender construction, and increasing welding gun can weld the range in hole.
