1, adhere 1/4-3/8 inch wire rod elongation (length of wire protruding from the welding torch head).

2, the use of small diameter wire welding sheet metal; welding thick plate using large diameter wire and large current welder. Check welder referral introductions.

3, use the correct wire welding workpiece. Stainless steel wire, welded stainless steel, aluminum aluminum welding wire, steel wire steel.

4, the use of the proper maintenance of gas. The carbon dioxide is very suitable for welding steel, but for welding sheet can be high temperature, should be the use of a mixed gas of 75% argon and 25% carbon dioxide welding thinner. The welded aluminum you can only use argon gas. Welded steel, you can also use a combination of three kinds of gases into a mixed gas (helium + argon + carbon dioxide).

5, reaches manipulating weld bead should adhere to the wire connected directly aligned with the weld pool marginal.

6, when the time division (vertical welding, horizontal welding, overhead welding) welding operation in a non-normal orientation, should insist on a small molten pool to reach the best handling of the weld bead, and the use of the smallest diameter of the wire as possible.

7, ensure that you use wire scale sets of mouth, liners, drive rollers match. Imported pumps

8, often finishing gun liner and drive rollers to adhere to the welding torch mouth no splash. If the welding torch obstruction perhaps wire feed ring true, it will replace it.

Welding, try to stick to the welding torch vertical to prevent the wire feed problems.

10 hands also use theMig Welding Electrodeoperation in order to ensure the stable welding torch, and do to be able to do so. (This same applies to the stick welding, TIG welding and plasma cut).

11 spools of wire feeder and drive wheel tightness conditioning just meet wire feed, do not overtighten.

12, when not in the wire, save it in a clean and dry, address, prevent being contaminated and affect the     Mig Welding Wires.

13, the use of DC reverse polarity DCEP power.

14 drag (pull) The Welding Torch techniques can achieve deep penetration and a narrower weld. Push gun techniques can achieve a shallower and wider penetration of the weld.
