Best Selling in Past 6 Years
1. Mature and reliable main circuit with balanced reactor and thyristor in dual inverse-star form, each moment has two thyristors work in same time, high efficiently
2. Rigorous process design, regardless of harsh environments or reload will operate properly
3. End voltage and current adjustable, regulate that help to make up the crater defects at the end of welding
4. With voltage and current adjusted separately/simple synergic function, whether newbies or skilled welders can easily operate.
Tips: If welding cable is longer than 5m, dual-driven wire feeder will be a better choice to reach better welding performance.

- Q:What is the straight line mark on an argon arc welding machine?
- A straight line is an ordinary DC output gear. The the Great Wall icon is the AC square pulse output chart. 2T is the switch on the welding torch, manual control welding machine switch. 4T is automatic welding without welding gun switch control.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:Can argon arc welding machine weld copper?
- Tolerable。TIG TIG welder MIG TIG welding machine can weld copper and copper alloy material workpiece.
- Q:It is not water-cooled argon arc welding machine, but the welding torch is water-cooled. Can it be connected with water cooling?
- No, it's not necessary.Welding torch for water cooled argon arc welding machine, suitable for high current welding operation. The welding gun is relatively bulky.Common natural air-cooled argon arc welding has a small working current and can be cooled by itself.
- Q:When argon arc welding, the old arc is what causes the current to be smaller, so the arc begins when the gear is turned up!
- 1, to see if you are using pulse argon arc welding machine.2, if yes, that is, you adjust the switch wrong, using the pulse up.3, if not, you said that the current is smaller, just as the switch begins, the arc begins.4, the reason is argon arc welding and manual arc welding machine welding machine is dropping characteristic and we use the same current voltage is high, can maintain the arc burning, current voltage drop, low voltage normal combustion can not keep the arc start off the arc.5, for these reasons, I estimate that the power of your welding machine is small, the range of use is already its limit, so the high current is always broken.
- Q:Can the direct current welder be used as an argon arc welding machine?
- ZX7 inverter series DC welding machine can be used as argon arc welding. Arcing mode is contact arcing!
- Q:What causes leakage when welding argon arc welding machine?
- Surface treatment has an impact on spatter, but it won't be as serious as you say. Heavy wire and welding current should be considered. For many reasons, such as the workpiece is not polished clean, rust, oil, argon impurities, and so on
- Q:How to use the reallink argon arc welder WS200S gas delay switch?
- 2.5S and 5S conversion, how long will it take to use?
- Q:How can argon welding be used to weld copper material? What do you need to have? Is the argon arc welding machine OK?
- The manual argon arc welding of brass can be made of standard brass wire: wire 221, wire 222 and wire 224, and it can also be used as filling material with the same material as base metal.Welding can be done by DC or AC. When welding by alternating current, the evaporation of zinc is lighter than that of direct current. Usually, there is no need to preheat before welding. Only when the thickness of the plate is relatively large can it be preheated. Welding speed should be as fast as possible. The weldment shall be annealed at 300~400 degrees after welding to eliminate the welding stress so as to prevent the weldment from cracking during use.No other things, general argon arc welding machine can be.
- Q:What's the price of argon arc welding machine?
- From hundreds to thousands, or even tens of thousands.1 、 brand welding machine:The production of welding machine manufacturers at home and abroad very much, have a well-known brand abroad such as Lincoln, Miller, Pegasus PL, domestic use very much; such as domestic Jiangsu Fenghua, Shandong, Beijing, Shenzhen Aotai era, Guangzhou raylink peak fire and Shanghai Weiteli welding machine and other domestic.2, non brand welding machine, especially 220V, also a few hundred dollars.
- Q:What is the reason that argon arc welding machine doesn't strike fire?
- The electrical switch is not connected, or there is a potential inside it.
