Q: Aluminum welding. Argon arc welding machine can weld aluminum, aluminum welding and argon arc welding which is cheaper: AC / DC argon arc welding machine can, argon welding should be cheaper, use less electricity, not the high technical content of aluminum. Do not know if you do not understand, ha ha, do not understand, ask me,

Q: AC and DC pulse square wave argon arc welding machine operation method?: This problem can be formed in many ways1. the current is too small2. argon is insufficient or not opened3., the input power line is too small or too long, resulting in insufficient flow4. switch improper adjustment, according to the material needs spot welding, or to blow welding, tune 2T or 4T function [various welding machine function is different, look at several instructions]5., the main problem is more experience, practice there is a touch, and more advice to the bottom of the master6. uniform solder joint without welding wire welding conditions can keep gold. Blue. A word is passed to any white when mixed to 6000 to 1W.RMB per month.7., you choose this function of welding machine is still very wise, two words easy to use...

Q: The current is too small to the maximum, indicating more than 300 or not: Adjust the flow of argon argon flow is too small, weak and feeble protection gas, protection effect is not good, easy to produce and weld defects such as oxidation pores; if the gas flow is too large, prone to turbulence, the protection effect is not good, but also affect the stability of arc burning. The welding of position 1 does not require argon protection to the parts, only the gas flow of the welding gun is adjusted, and the flow rate of argon is adjusted to 7~10 l/min.

Q: The difference between AC argon arc welding machine and DC welder: The difference between AC argon arc welding machine and DC welder:1, DC TIG welding, the DC positive connection with argon gas protection, with between the electrode and the welding arc in certain requirements (welding current), heating and melting of the parent material, adding wire wire to melt into the molten pool, the formation of weld cooling.In addition, 2 pulse argon arc welding, DC TIG welding specification, can independently adjust the peak current, base current, pulse width, pulse period or frequency parameters, compared with DC argon arc welding has the following advantages:(1) increasing the depth to width ratio of the weld, the width of the weld can be increased to 2:1 when the stainless steel is welded(2) to prevent burning, in the thin plate welding or thick plate backing welding, with the peak current through the time, the weldment is welded through, before the pool obvious subsidence, go to the base value current, make the metal solidification. Also, there is a small current to maintain the arc until the next peak current is circulating.(3) reducing the heat affected zone and welding the heat sensitive material, reducing the pulse current through the time and the base current value can reduce the range of the heat affected zone to the minimum, so that the welding deformation is small.(4) increase the stirring of the molten pool, at the same average current value, current value than a constant current high current pulse peak, so the arc force, strong mixing effect, which helps to reduce joint at the bottom of the hole and may not fusion phenomenon. In small current welding, the higher pulse current peak current enhances the arc stiffness and eliminates the arc drift phenomenon.

Q: Why argon arc welding only fires without current?: There may be a high pressure package will be bad, but generally not high voltage package failure. Argon arc welding machine is not a simple welder with argon gas protection. On the one hand, the no-load voltage is low; on the other hand, it is possible to reduce the capacitive capacity of the high voltage arc ignition circuit.Argon arc welding machine slow ignition, this normal. After pressing the switch of the welding torch, the electromagnetic valve in the welder is started.Argon arc welding machine, are ahead of its protection role of gas welding. Argon is used to blow air around the weld line of the workpiece to be welded so as to avoid penetration of the weld through the air. The arc then starts and enters the normal welding process.Each brand of each model of argon arc welding machine, the delay time is different, some welding machine can be adjusted.Argon arc welding, that is, tungsten inert gas arc welding, refers to the use of industrial tungsten or activated tungsten as non melting electrode, inert gas (argon) as the protection of welding methods, referred to as TIG.

Q: Welding aluminum parts by argon arc welding, I made a control cabinet, servo motor to drive the welding torch to move, and control welding current, control welding stop,There are 2 servo motors in the cabinet,.1 PLC. When I arc, the high frequency of the welding machine will affect my welding machine, and the servo motor will run around,PLC the first second inputs X1.X2 will flash. When the control panel is out of power, the welder will start arcing, and the alarm light on my Cabinet will flash (no power is on)The alarm beeps, too. Put awayA filter in front of my PLC with the servo driver, but the driver in front of hell no isolation transformer, alarm lamp in front of no isolation transformer, servo driver CN1 input port with no shielding line: 1, do power isolation, control circuit power supply, servo motor power supply must go through the isolation transformer;2, at the same time, the input signal of the PLC (especially from the welder) must be isolated;3, PLC output to the welding machine parts have to be isolated by relay;4, select the appropriate PLC, design and installation wiring should be standardized.

Q: Can argon arc welding machine be used as DC welding machine?: It's difficult to estimate.Because argon arc welding is usually less current, only a small arc is produced. The ordinary welder needs a larger current.

Q: What is a rectifier arc welder?What advantages does it have?: In brief, the rectifier arc welding machine is in the AC arc welding machine after the secondary winding, plus a set of high-power SCR rectifier system, used to adjust the output voltage to adjust the welding current. It is used for welding stainless steel, low and medium carbon steel and ordinary low alloy steel parts. The utility model has the advantages of light weight, fast reflection speed, large current adjustment range, etc..

Q: What's the difference between WSM argon arc welding machine and TIG argon arc welding machine?: WSM is DC pulse argon arc welding, which has more pulse function than TIG.

Q: What does the base current and the peak current mean on an argon arc welding machine? How to adjust?: The range of the maximum no-load voltage is not good. The machine itself is set up
