Description

{WIRE PROTECTION GUIDE FOR FAIL-PACK}

This wire devise is related to a wire protection guide for a fail-pack, and in particular, a wire is drawn out to the outside through a flexible wire drawing member provided inside the fixed guide member.

Generally, CO ₂ arc welding uses carbon dioxide gas instead of inert gas such as argon or helium. Since such carbon dioxide gas is not an inert gas, a high-temperature arc is highly oxidative. Therefore, when an uncoated electrode is used, Blow holes and defects tend to occur. Therefore, a wire containing a deoxidizer is used to solve this problem.

In this case, since an uncoated wire is used for carbon dioxide gas welding, a device for preventing oxidation even if the wire contains a deoxidizer is required. In the conventional case, a wire reel in which a wire is wound is left in the atmosphere, And it is already oxidized by the moisture contained in the atmosphere by simple use by putting it in a protection hole, and welding defect is generated from this.

In order to solve such a problem, a wire protecting apparatus for carbon dioxide gas arc welding of Registration Utility Model No. 20-0423772 (August 4, 2006) has been proposed, and the proposed wire protecting apparatus has been proposed A heater is installed and a temperature controller connected to a heater is installed outside the main body to prevent oxidation due to moisture.
