Hot wire TIG welding, is to install hot-wire device additional on the basis of traditional machine structure, by independent before welding wire feeding welding pool
Welding wire power supply is preheated to welding wire, can accelerate the burn-off rate of welding wire and mother metal, improves welding efficiency, arc stability, weldering
Seam uniform in shaping is attractive in appearance, function admirable.But during being preheated to welding wire, preheating temperature is uncontrollable.If
Heat time is long so that welding wire preheating temperature is too high, then welding wire is introduced into molten bath and then melts, it is impossible to carry out normal weld, very
The adverse consequences such as burn-through are overheated to welding wire is caused；If the heat time is too short, welding wire preheating temperature is too low, easily causes heated filament
TIG is welded to no effect, and the problems of welded quality such as lack of penetration, undercut are easily caused in welding process, therefore the preheating temperature of welding wire is
One key issue of hot wire welding, it directly affects the efficiency and quality of welding.Therefore, we have proposed a kind of temperature-controllable
Hot wire TIG welding's auto-power-off device.
Utility model content
The purpose of this utility model is the hot wire TIG welding's auto-power-off device for providing a kind of temperature-controllable, with solution
State the problem proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of hot wire TIG welding of temperature-controllable is automatic
