The second welding is called carbon dioxide gas shielded welding, and the argon arc welding (TIG) is called tungsten arc welding. The second welding is a fusion electrode welding, and TIG is a non-fusion electrode welding. Second, the welding spatter is relatively large, and can weld low carbon steel, low alloy steel, low alloy high strength steel, etc. TIG generally welds thin plates or do bottom welding, and AC power can weld aluminum.
Second welding: using wire reel, in addition to gas cylinders, wire feeding system is also attached. The gas meter needs to be electrically heated. Otherwise, anti-frost is blocked. The mediation parameters are air pressure, current, air supply advance time, air supply delay protection time, and wire feed speed.
