Q: What are the characteristics of rotary DC arc welding machine?: The machine is composed of engine (diesel or gasoline generator (drive), single-phase or three-phase AC arc welder,) and composition, is a set of power generation, power supply and power as an independent power system, can be used as a generator, and can be used as a welding machine, which is called generating welding machine.

Q: Can argon arc welding machine be equipped with automatic wire feeding device?: Can. There are now automatic argon arc welding (such as Zhejiang, Kell, NZA-200).

Q: Some people say that 300 of people say 400-500, because we are out of the product, so the work time is relatively long, 6-7 hours a day, and sometimes work overtime, perennial welding, so the durability requirements are relatively high! Which brand is better? How much is it? (it used to be 315 electric welder, and now it's all replaced by argon arc welding machine.) Don't advertise. Please give me some pertinent advice. Thank you！！: Suggest you use the New Asia WS series, you can use WS-315A. Because our company perennial use welding machine, choose more varieties, or New Asia, feeling good, you can try

Q: What do you mean by "ground arc" of argon arc welding machine? Is it because it doesn't arc or is it connected directly to the ground to prevent electric shock?: Some of the ground wires come from the positive electrode, some from the negative electrode, and the electrodes are marked or referenced. The electrodes are directly connected to the welded metal objects before welding.

Q: Shanghai Dayang WSE5-315 wsem and Shenzhen Jiashi of square wave AC DC inverter argon arc welding of WSE315, the function is the same? Can it be completely replaced? If welding, auto cylinder and cylinder head can be used? Why is the former heavy 195KG and the latter only 38KG?: Difference between SCR and invert argon arc welding1, SCR rectifier is AC rectifier 50HZ into DC output, by changing the thyristor conduction angle to change the size of the output, the output waveform is not smooth, so the welding effect is not very good, the arc and other control functions slightly worse.Inverter argon arc welding machine is AC rectifier, through IGBT inverter, the intermediate frequency transformer step-down, after two times the rectified output, output waveform, change the output by the pulse width modulation control of IGBT inverter conduction time size. The arc striking and thrust current are easy to control.2 、 SCR rectifier welding machine is bulky, bulky, inconvenient to carry and move; and inverter argon arc welding machine inverter frequency as high as 20-30KHZ, so the transformer is small, light weight, easy to handle.3, inverter welding power inverter than the argon arc welding machine power saving of about 30%.4 、 inverter arc welding machine control and main circuit is relatively simple, high reliability, little trouble, easy maintenance.

Q: Can the inverter DC argon arc welding machine weld aluminum?: If helium is used, aluminum can be welded and operated in the same manner as argon arc welding;If argon is used, the usual method of operation can not be soldered to aluminum;If argon is used to weld the tungsten electrode, it is possible to solder the aluminum, but the tungsten is burned rapidly and can be used temporarily, especially when the current is relatively small, such as under 50A.Of course, it's better to use AC argon arc welding machine.

Q: Argon arc welding machine general how much money? Which brand is better?.: Wuxi Han God, Wuxi Fenghua, buy about 800 on it.

Q: What do you mean by "WS.TIG.ZX7." on argon arc welding machine? What are the characteristics of each?: WS and "TIG" are the meaning of "argon arc welding". The domestic use of WS means "TIG" in foreign countries, and "ZX7" means "hand arc welding".

Q: How to weld aluminum material with argon arc welding machine: 1) AC argon arc welding machine shall be used. The use of a cathode crushing needle in the process of welding produces three aluminium oxide (two aluminum oxide).2) the choice of black glass. Should be more than you usually weld stainless steel lenses plus one to two, in order to better see the molten pool.3) suitable material selection. Select the suitable filling material according to the aluminum material.4) the choice of gases. Rich argon gas (nitrogen + argon) and argon gas can be used in two ways.5) current selection. According to your personal habits, you can meet the requirements
