1. Cotton canvas fabric should be selected. In welding work, polyester or other chemical fiber fabrics will become liquid and stick to the body when heated, which is easy to cause burns; Cotton work clothes are resistant to high temperature, and even after burning, they will only turn to ashes without deformation. Rongyi has several pictures of work clothes made of cotton canvas fabric, which are wear-resistant and high temperature-resistant, and are the first choice for electric welding work clothes. 2. In terms of color, it is recommended to choose white. Because welders' clothing should be fire-proof, it is generally cotton fabric, but the color fastness of cotton fabric is not easy to control, and the color will turn yellow or red after strong light irradiation, while white (usually bleached) is highly reflective and brighter, which can protect the body more effectively. 3. All-position welders shall be equipped with leather work clothes. 4. When welding and cutting at high altitude, in order to prevent sparks and slag from splashing on the head and shoulders, the welder should put a towel around his neck and put on shoulder pads, long sleeves, aprons and shoe covers made of flame retardant materials. 5. The work clothes worn by welders should not be wet, and the length of pants should cover the vamp. There shall be no damage, holes, gaps or grease on the work clothes.
