Welding clamp

Abstract

Electrode holders comprise a machine body; the machine body comprises a steel bar clamp and a main body; the front part of the main body is a welding rod clamping part, and the back part of the main body is a welding wire connecting part; one end of the steel bar clamp and the end part of the welding rod clamping part are in a non-aligned state to cooperate to clamp a welding rod tightly; the other end of the steel bar clamp is fixed on the main body; through-holes are formed in the welding wire connecting part, and the welding wire is connected through the through-holes; a thermal protective device is arranged on the welding wire connecting part. The electrode holders have the advantages that the product structure is simple, the possibility of damaging components is reduced, and a thermal protective device designed to be concave-shaped is adopted at the welding wire connecting part. By utilizing the elasticity of the steel bar clamp to cooperate with the iron main body to clamp the welding rod, the shape shifting is simple, the cost is reduced, and the possibility of damage is reduced.

Description

technical field [0001] The invention relates to the technical field of welding tools, in particular to an electric welding tongs. Background technique [0002] At present, electric welding tongs on the market are generally composed of a main body pressure rod and a spring. The main body and the pressure rod are connected by a shaft, which is easy to be lost and damaged during operation, making it unusable. The spring is easily damaged by fire during operation, and the elasticity is seriously weakened due to long-term use, resulting in loss or inconvenient use. Secondly, the electric welding tongs are pulled during operation, coupled with the thermal loosening effect, it is very easy to cause the electric welding tongs to heat up and cause the service life to be shortened or damaged. Furthermore, when the electric welding pliers touches the fire when the contact is poor, it is easy to cause damage to the position where the welding rod is clamped, making the electric welding...
