Carbon dioxide gas shielded welding MIG gas shielded welding 1. Maintain 1/4-3/8 inch wire rod extension (the length of the welding wire from the torch head). 2. Use a small diameter wire when welding thin plates; when welding thick plates Use a large diameter wire and a high current welder. Check the specific performance of the welding machine recommendation introduction. Carbon dioxide gas shielded welding MIG gas shielded welding

1. Maintain 1/4-3/8 inch wire shank extension (the length of wire coming out of the torch head).
2. Use small diameter welding wire when welding thin plates; use large diameter welding wire and high current welding machine when welding thick plates. Check the specific performance of the welding machine recommendation introduction.
3. Use the correct wire to weld the workpiece. Stainless steel welding wire welding stainless steel, aluminum welding wire welding aluminum, steel welding wire welding steel.
4. Use the correct shielding gas. Carbon dioxide is very suitable for welding steel, but it can be too hot for welding thin plates. A mixture of 75% argon and 25% carbon dioxide should be used to weld thinner materials. For welding aluminum, use only argon gas. When welding steel, you can also use a combination of 3 gases (helium + argon + carbon dioxide).
5. For best bead control, keep the wire directly aligned with the bonding edge of the weld pool.
6. When the welding operation is in an abnormal position (vertical welding, horizontal welding, overhead welding), the weld pool should be kept small to achieve the best control of the weld bead, and the wire with the smallest diameter should be used as much as possible.
7. Make sure the wire size you are using matches the tip, liner, and drive rollers.
8. Clean the torch liner and drive roller frequently to keep the torch muzzle free of spatter. If the torch mouth is clogged or the wire feed is not smooth, replace it
