1. Instructions for using argon arc welding:
The instructions for using argon arc welding are as follows: Prepare an argon gas cylinder and flow meter: Before welding, ensure that the argon gas cylinder is filled with argon gas and install an argon flow meter.. Connect the argon cylinder to the air inlet on the back panel of the welding machine using a gas tube, ensuring that the connection is tight to prevent air leakage. Connect the welding gun and welding machine: Connect the argon arc welding gun, gas connector, cable quick connector, and control connector to the corresponding sockets of the welding machine. The workpiece is connected to the "+" terminal plug on the welding machine through the welding ground wire. Connect the power cord and check the grounding: Connect the power cord of the welding machine to ensure reliable grounding to prevent electric shock accidents. Select welding mode: Depending on the welding needs, choose AC argon arc welding or DC argon arc welding. Synchronize the line switch and control switch to the corresponding AC or DC mode. Set welding method: Set the welding method switch to the "argon arc" position. Adjust argon flow rate: Open the argon cylinder and flow meter. Pull the gas test switch to the "gas test" position, check if gas flows out of the welding gun, and adjust the airflow accordingly. After debugging is completed, pull the gas test and welding switch to the "welding" position. Adjust welding current: Use the current adjustment handwheel to adjust the size of the welding current. Clockwise rotation reduces the current, while counterclockwise rotation increases the current. The range of current regulation can be limited by changing the switch of the current sens
2. Is mandatory calibration required for argon gas cylinder flow meters used in welding?
Yes. According to the verification regulations for flow meters, it is necessary to conduct mandatory metrological identification for argon gas cylinder flow meters used in welding. Argon gas is used for inflating light bulbs and for arc welding of stainless steel, magnesium, aluminum, etc. with infiltration, also known as "Tan Sunji argon arc welding". Kaicong

4. Conversion between hydrogen flowmeter and argon flowmeter
The conversion core between hydrogen flowmeter and argon flowmeter lies in the difference in gas density, which can be quickly calculated through standard density values and conversion formulas.. 1. Conversion principle Flow conversion is based on the same operating conditions, where the volumetric flow rate is inversely proportional to the square root of the bulk density of the gas cylinder. The formula is Q ₁/Q ₂=√ (ρ₂ trapped/ρ₁), where Q is the volumetric flow rate and ρ is the gas density
. 2. Key parameters: Under standard conditions (0 ° C, 101.325kPa), the hydrogen density ρ H ₂ is 0.0899 kg/m ³ and the argon density ρ Ar is 1.784 kg/m ³. If the actual working conditions dev
