Narrow Groove Gas Metal Arc Welding Torch

1 . A narrow groove gas metal arc welding torch, comprising:

a. a power block having electrical, feed welding wire, water cooling, and shielding gas connections;

b. a dielectric attached to the power block;

c. a gas shield attached to the dielectric that defines an annulus between the shield and dielectric;

d. a contact tip attached to the power block that receives and controls the curvature of a feed welding wire; and

e. a shielding gas diffuser provided on the dielectric.

2 . The narrow groove gas metal arc welding torch of claim 1 , wherein the portion of the contact tip in contact with the welding feed wire has a radius of curvature smaller than the natural radius of the feed welding wire.

3 . The narrow groove gas metal arc welding torch of claim 1 , further comprising a shielding gas outlet port provided in the dielectric such that shielding gas is delivered in the annulus defined between the molded dielectric and the gas shield.

4 . The narrow groove gas metal arc welding torch of claim 1 , wherein the contact tip is formed of copper.

5 . A narrow groove gas metal arc welding torch, comprising:

a. a power block having electrical, welding wire, water cooling, and shielding gas connections;

b. a dielectric attached to the main body portion, said dielectric having an outlet for shielding gas;

c. a gas shield attached to the dielectric that defines an annulus between the gas shield and dielectric;

d. a diffusing gas outlet provided on the dielectric to deliver shielding gas in the annulus defined between the dielectric and gas shield attached to the dielectric.

e. a contact tip attached to the power block that receives and controls the curvature of a welding feed wire, with the portion of the contact tip in contact with the welding having a radius of curvature smaller than the natural radius of the feed wire; and

f. a diffusing gas outlet provided on the dielectric.
