In the present embodiment, which further includes hinge 12 and head hoop 13, and hinge 12 connects head hoop 13 and mask body
1, mask body 1 is rotated relative to head hoop 13 to be user-friendly for wearing, compares hand screen, the electric welding
Mask can liberate the both hands of user, so as to both hands cooperation, coordinative operation.
Image before the present invention will be welded by two photographic devices and in electrode welding process is presented on liquid crystal display in real time
On, it is directly observed without human eye, thus avoid human eye direct-view electric arc and the injury by harmful arc light, specifically:
Image when preceding electric welding and striking can be clearly shot by zero diopter photographic device 4, operator passes through the image energy
The position of solder joint, the position deviation of solder joint when striking being avoided to operate are checked in time；
The speed of arc manipulation, direction and the state in molten bath when can obviously observe weld job by optical filtering photographic device 5,
More preferably to guarantee welding quality；
Liquid crystal display 8 image captured by two photographic devices can be presented in real time, it can be achieved that double screen, single screen show from
By switching；Since the arc process time is short and can issue infrared ray, ultraviolet light and high-intensitive visible light, convenient for behaviour when shuangping san
Author operates striking step, smooth transition striking and arc manipulation step；
Photovoltaic battery panel is a kind of semiconductor material, and greater band gap can be the ultraviolet light in electro-welding arc to infrared light
All luminous energy be converted to electric energy；Charge-discharge control circuit plate 223 can be according to the generated energy and electricity consumption of equipment of photovoltaic battery panel 21
Amount, the charge and discharge of real-time monitoring photovoltaic battery panel 21 and battery 222.Meanwhile after work, which is placed on
According to power generation is shone under the sun, electricity can be used for the use of the electric appliances such as mobile phone, mini fan, can also be by alternating current to battery
222 charge, and then use using the electric welder's helmet as mobile power source.
The above is only the preferred embodiment of the present invention, the range implemented of the present invention that therefore, it cannot be limited according to, i.e., according to
Equivalent changes and modifications made by the invention patent range and description, should still be within the scope of the present invention.
