5. The chemical properties should meet the requirements.
6. Metal parts should not be connected between the outer and inner materials of the glove to prevent electrical conduction.
Classification
Welder protective gloves are divided into two types according to their performance.
Class A: Low flexibility (with higher other performance)
Type B: High flexibility (with lower other performance)
size
The minimum length of welder’s protective gloves should meet the requirements of the following table:
skills requirement
1. Structure:
