Q: Taobao online selling Songle welding machine and welding machine which 250 Andre

Songle welding don't buy, I bought a Taobao Songle argon arc welding machine using 250A on the bad days, looking for customer service, the woman does not understand what a power connection is wrong, not warranty, in someone's home I two welder welding bars are in use, a beacon. It is not the first day, he found it strange that an excuse to call, he hung, now at home, nine hundred of the welding machine, this didn't earn, the boss still curse the comments, it is a shame, who buy Songle is silly B

Q: What is the reason that argon arc welding machine doesn't strike fire?

Check the control switch and the circuit is short, if not, then look inside a gap is too large surface is clean. No problem, according to the line has been checked. Some welding machines are set up without air flow and arc free. If the arc striking device is striking the arc, check the gun belt.

Q: Welding machine model is WSM-315G, without water cooling, can be connected with water welding gun, because there is a warehouse

To see your current use, even if the interface is the same, do not recommend, water-cooled argon welding torch cable diameter of not more than 18 square, and 315 machines etc should be equipped with more than 35 square wire

Q: I want to weld pressure 3.52MPa pipe, argon arc welding, manual welding cover surface. In the online search WS WSM, argon arc welding and WSME three models, it is not clear which is suitable for professionals to give guidance, please, thanks in advance!

Inverter: ordinary argon arc welding, you welding is suitable.Pulse: argon arc welding with many pulsed functions, which can be soldered to an automatic arm (pulse).Square wave TIG welder: argon arc square wave function, using square wave welding aluminum oxide layer on the surface of the square wave (open aluminum oxide layer with high melting temperature, need to open the square wave, the internal aluminum low melting temperature).

Q: Can tig200s argon arc welding machine weld aluminum?

Able to weld aluminum, but can only be welded, need to be fully polished before welding and welded in 10 minutes to avoid oxidation of aluminum.For long welded seams, WSME argon arc welding machine is recommended for welding. For long welding, there is an oxide film on the surface of aluminum, and the oxide film needs to be broken during welding. If the oxide film fails to break, it will cause slag inclusion and cracks. And aluminum melting point temperature is low, heat dissipation, welding technology is not enough, often lead to welding wear phenomenon, so the need to use pulse, reduce heat input.E means alternating current has the function of breaking oxide film, and M indicates pulse, which is very suitable for welding thin plate.Thick plate, then WSE250 can, the price is almost 2500-3000 (mid-range welding machine). The generic one is WSME315, but it's a bit expensive.

Q: Commonly used electrical welding machine (AC) why, some of the object is AC welding machine, and some of the object is AC arc welding machine, what is the difference between the two; do not pull useless, I am not high culture, thank you for your cooperation!

The two standard methods have the same meaning, and the standard method has the following:AC welderAC arc welding machineArc welding transformerRefers to the same thing, is the simplest welder, the AC through the transformer to reduce voltage, you can welding. There is nothing profound. Absolutely. I participated in the naming standard of the electric welding machine.

Q: There are several argon arc welding machines in our factory. There is a problem with it. To put it plainly, sometimes it can lead to arc. Sometimes it is very close and can not arc. Abnormal welding. Come on, master!

First, it may be too high or too weak or high frequency! Second, tungsten quality is poor, third welding torch copper wire open!

Q: Argon arc welding machine automatic leakage, how to repair?

First of all, the power off state, look, out of breath Two cases. First, vent, OK, you're lucky, but the solenoid valve is broken. Change a few tens of dollars. Two, do not vent the gas, the circuit is out of order, you need some electrical knowledge. 1, check line, along the two lines of solenoid valve to the circuit board, control its relay, replace it. If it's not good, then if you're a little level, you'll continue to know how to do it at this step. If you don't know, then I'll say yes. Recommend professional maintenance.

Q: Can argon arc welding machine weld copper?

Can. But the cost is high. It is difficult to weld brass (including zinc) by argon arc welding.

Q: What is the optimum distance between the arc striking of argon arc welding machine?

Two discharge points per discharge point 0.1~0.3mm, isoelectric point 0.2~0.5mm is suitable for delivery.
