Environment-friendly welding device convenient to adjust

The invention discloses an environment-friendly welding device convenient to adjust. The device comprises a base, and an annular groove is formed in the top face of the base. The invention relates tothe technical field of machining. According to the environment-friendly welding device convenient to adjust, most of a welding area can be shielded through cooperation of a supporting mechanism and aprotection mechanism, harmful light radiation generated by the operation area can be filtered out while the observing of the operation area from the periphery is not affected, and it is avoided that the harmful light radiation affects body health and operation of other personnel; and most of light radiation can be filtered, the protection area is more comprehensive, the protection effect is better, an operator does not need to wear too much protection equipment, operation of the operator is facilitated, and meanwhile the protection mechanism can follow the operator to adjust the direction according to the actual operat
