Satisfactory welding joint can be obtained both in root pass welding and arc welding. It can also weld some low alloy steel, such as 09Mn2Si, 16Mn, 09Mn2V. etc. Instructions: a.Suitable for using shielding gas at the speed of 20-25 liters per minute. b.Windshield must be set up in the welding zone, due to gas porosity may be caused by strong wind.
For GMAW-CV the welder selects the wire feed speed (WFS) on the wire feeder unit and an appropriate voltage on the welding power supply. The internal circuitry of the power supply then supplies an appropriate amount of welding current necessary to maintain a stable arc.
This constant power source also controls the welding voltage/current association, since in MIG, the wire feed speed determines welding current, and the power source voltage level controls arc length. MIG welding guns – 2 types of welding guns There are two

Semi-automatic welding: Welding with equipment that supplies continuous wire feed with or without means for mechanical travel. Manual manipulation by the welder of one or more of the variables of speed of travel, guidance, and direction of wire is involved during
11/7/2019· In MIG welding, the electrode wire is continuously fed through a cable liner in the welding gun, and typically you need a spring steel coiled liner for steel appliions. Because these liners are steel, they are rigid, resist buckling, and have a long life.
CO2 is a good choice for welding thick material which requires deep penetration. If cost is a major factor, it is the least expensive shielding gas to use. Argon / CO2 MIX: The ratio of Argon to CO2 can range from 75 percent to 95 percent Argon mixed with 5 percent to 25 percent CO2.
The principles of MIG welding are outlined including process characteristics, metal transfer modes, shielding gas types and process appliions. For droplet or spray transfer, a much higher voltage is necessary to ensure that the wire does not make contact i.e
A. Proper Welding Wire dimensions. With regard to thin materials employ a smaller size wire and then for thicker materials an increased gauge wire. For a guideline, for 22 to 26 gauge material utilize.024″ wires, for 20 gauge to 1/8″ materials utilize.030″ wires and also 1/8″ up to …
