Technical Parameters

Q:Argon arc welding machine automatic leakage, how to repair?: Could you explain in detail where the leak is?

Q:Argon arc welding machine for the first time. Can you tell me how to cut it?What's the gas for?: Same as argon arc welding. When purchasing the plasma cutting hand, watch the size of its control socket, the key models are many.

Q:I bought an argon arc welding inverter, DC, but I can't find the place where argon is filled. Can I use the argon needle and plug it directly?: No, like carbon dioxide welding, argon protects and keeps the arc. You don't use argon to weld it all. It doesn't work well.As for the following 0.2mm only plate welding, it is obvious that the mechanical properties of the requirements are not high, you can first test, if possible, the best. But we always use protective gas for welding.

Q:What is the cause of the no ignition in the DC argon arc welding machine?: Not only a gas argon arc welding, argon arc welding and gas protection, before use to check whether the line of gas pipeline, is not fully open, the welder is not FM correctly, if no problem, that is the machine fault, I hope to help you

Q:It's only a small electrical shock when soldering..: Check if the discharge device is sparking or not

Q:What are the biggest differences between DC and arc welding machines? What characteristics do they have? They are good at welding what kind of metal materials: Alternating current welding machine: it is a special step-down transformer which is produced by alternating current through the welding machine, and then it is welded with low voltage and high current power. The utility model has the advantages of simple structure, convenient maintenance, no magnetic deviation when welding, and wide application. Use ordinary electrode, stainless steel electrode, cast iron welding rod, power welding machine, can barely use 506 welding rod. The base metal that can be welded is also extensive (only gold, silver, copper, tin and other special materials can not be welded)Direct current welding machine: the electric energy can be welded by alternating current through rectifier to dc. The utility model has the advantages of small size and light weight. Its structure is a little complicated, and the maintenance is difficult. But its performance can replace the AC welder completely, and the application is more extensive. Both special materials and special welding electrodes can be welded.I spent 17 years as a welder, hope I can help you.

Q:I want to buy an argon arc welding machine. I don't know which manufacturer is good. Please let me know, and the price. If so, thank you very much.: I want to buy an imported argon arc machine. I don't know which one is good. Thank you

Q:How much electricity does an argon arc welding machine use in a day?: Less than the electric welder, look after the welder marked

Q:That kind of argon arc welding machine can weld copper and solder aluminium. What brand is good, and what's the price?: You can choose WSE-400-1, this machine is ok. You can search it online!

Q:You ask about the quality of argon arc welding machine which brand is good, the requirements of aluminum welding, welding and cutting thickness below 20mm, 12mm can also be used, or DC inverter AC / DC, what model is appropriate, about how much the price, thank you!: Salesman to answer, are deceptive, the market share of the most is the best.
