However, before using the co2 welding torch, it is also necessary to clean up the groove of the co2 welding torch and the oil stains, paint layer, oxide scale and iron metal and other debris on the surface of the two sides.
2. Check the equipment: Check whether the power cord of the quality co2 welding torch is damaged and whether the grounding of the ground wire is reliable. Whether the contact tip of the co2 welding torch is in good condition and whether the wire feeding mechanism is normal. The polarity of the quality co2 welding torch has been selected correctly.
3. Check the gas path: the gas and the gas path system of the quality co2 welding torch includes carbon dioxide gas cylinder, preheater, dryer, pressure reducing valve, electromagnetic gas valve and flowmeter. Before use, check whether the connection of each part of the quality co2 welding torch is leaking, and whether the carbon dioxide gas of the co2 welding torch is smooth and whether it can be sprayed evenly.
