What is the Knowledge of Argon Arc Welding Machines that Novice Welders Must Know?

The argon arc welding machine is a machine that uses high-pressure breakdown arc starting method for welding. Argon arc welding is tungsten inert gas shielded arc welding, which refers to a welding method that uses industrial tungsten or active tungsten as non-melting electrode and inert gas (argon) as protection, referred to as TIG. Commonly used for welding of 6~10mm thick plates, double-sided single-sided forming back cover welding of thick plates. 160V TIG Welding Machine Classification According to the different electrodes, argon arc welding machines can be divided into melting electrode argon arc welding machines and non-melting electrode argon arc welding machines. Non-melting electrode argon arc welding Non-melting electrode argon arc welding refers to the arc burning between the non-melting electrode (usually tungsten electrode) and the workpiece, and an inert gas (usually argon gas) flows around the welding arc, which does not chemically react with the metal to form protecti

How to Adjust the Argon Arc Welding Machine?

1. Turn the DC and pulse switch to pulse. This switch is used to switch the output of the welding machine to DC or pulse. When the switch is in DC, the output of the welding machine is DC, otherwise, it is pulse output. It must be placed in DC state during manual welding. 2. "Base current" adjustment knob: This knob works in pulse state. Used to adjust the magnitude of the arc current maintained during pulse welding. 3. "Pulse frequency" adjustment knob: this knob only works in pulse state, it is used to adjust the number of pulse welding current (fast or slow). The higher the pulse frequency, the denser the welding ripple, and vice versa, the thinner it is. 4. "Pulse Width" (Duty Cycle): This knob only works in the pulse state. It is used to adjust the duration of the pulse welding current. The wider the pulse width, the relatively wide and deep welding seam, otherwise it is narrow and shallow. DC TIG Welding Machine Pulse duty cycle: It is only used duri

the Argon Arc Welding Machine Affect the Welding Effect

You must know that the argon arc welding machine is a kind of high-tech welding application equipment, which performs this series of spot welding steps in the form of high pressure. When I was studying physics in junior high school, I was exposed to the knowledge of electricity. Among them, the magnitude of current is also the most concerned point of electricity, because the magnitude of current will affect the normal operation and operation of various devices. Any kind of equipment has a certain voltage range and current range, and the size of the power is also determined according to the range of the two values. Therefore, the current size of the argon arc welding machine will affect the welding effect to a certain extent. DC Welding Machine The current and voltage of the AC arc change their direction every half cycle, and the arc discharge conditions change periodically, so it has an important impact on the stability of the arc and the work of the welding power source. The case is
