Electric welding holder

Abstract

This invention relates to an electrode holder, which comprises electrode holder body, spout cable grip and cable grip for connecting the electric welding machine, wherein the electrode holder body comprises connecting sleeve, knob inner and outer sleeves, and tong spout; between the connecting sleeve and knob inner sleeve, and between the inner and outer sleeve are sealed by collar seal individually; the up spout is hinged in the press handle through screw; the T-shape connectors of two kinds of cable grip are fixed and connected through protective adaptor, and the spout cable grip has up and low split-conductor cables, which connect up and low spout individually. Such structure can ensure the temperature of handle external surface perfect when working, and decrease the caloric power greatly; besides, it can obstruct and damp heat conduction between each part.

Description

technical field [0001] The invention relates to an arc welding device, in particular to a non-hot electric welding tongs with high welding efficiency using alternating current and direct current. Background technique [0002] At present, the welding tongs sold in the domestic market, after a period of continuous welding, the temperature of the outer surface of the handle will exceed 40°C, which makes the operator's hands feel uncomfortable, and sometimes has to suspend welding due to hot hands, reducing production efficiency. The main reasons for this hot hand phenomenon are unreasonable design and structure of welding tongs; defects in manufacturing process; inability to effectively block and dissipate heat, and inability to reduce heat conduction and other factors. The various electric welding pliers currently used mainly have the following problems in design, manufacture and use: [0003] 1. In the structure of the existing electric welding tongs, there are mostly three ...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to provide a kind of electric welding tongs, which has a reasonable structural design, can effectively solve the defects of suspending welding and reducing production efficiency due to hot handles in the prior art, and ensure the temperature of the outer surface of the handle of the electric welding tongs during the actual continuous welding process Moderate and not hot, significantly reduce the heat generated by the parts of the welding tongs, block and weaken the heat conduction of the parts of the welding tongs, fundamentally improve the welding working conditions and improve work efficiency
