Abstract

Disclosed is a welding helmet with a protection cover for a cartridge, being manufactured in various forms and capable of covering a cartridge of the welding helmet and thereby protecting the cartridge from welding heat and preventing melting of the cartridge. According to the present invention, the welding helmet comprising a helmet body covering an operator's face, an opening formed on a front of the helmet body, and a cartridge connected with the opening and equipped with an LCD panel which intercepts light emanating from a welding operation to protect the operator's eyes, further comprises a heat transmission interception unit formed on a front of the cartridge of the welding helmet to prevent surface deformation caused by welding heat.

Claims (6)

1. A welding helmet comprising:

a helmet body covering an operator's face, an opening formed on a front of the helmet body;

a cartridge connected with the opening and equipped with a rechargeable solar cell and an LCD panel to intercept light emanating from a welding operation to protect the operator's eyes; and

a protection cover formed on a front of the cartridge of the welding helmet to prevent surface deformation caused by welding heat, the protection cover comprising a front cover removably connected to an outer facing surface of the cartridge, the front cover including a first opening for the LCD panel at a lower part thereof and a second opening for a rechargeable solar cell at an upper part thereof.

2. The welding helmet of claim 1 , wherein the protection cover is made of any one material among silver foil, a heat resistant resin plate, a heat resistant film, a heat resistant coating layer, and a heat resistant metal plate.

3. The welding helmet of claim 1 , wherein the protection cover is formed by vacuum-deposition coating a partial or the whole surface of the LCD panel formed at the cartridge.
