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 about Panasonic argon arc welding machine in Tangshan? Detailed point! Thank you: I think one price per share, you say?

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?: In order to form a loop, not a safety problem, the welding gun is an electrode and the ground wire is an electrode, so as to form a welding arc

Q: Isn't it? I feel OK, the first time there is no argon, the air can be usedThe nitrogen reacts with the air after the arc is electrically shocked, producing nitric oxide and starting to act as a protective agent. Wrong, this reaction occurs only at the periphery, and the reaction at the nozzle is pure nitrogen. There is no such problemHarmful gases can be solved by ventilation. What I care about is that if the metal nitrides are produced during welding, they will get very good welding hardness and corrosion resistance. Can they do so?The pure air did not work, and the tungsten electrode was soon ablated,: Argon is an inert gas that blocks air and protects the workpiece from oxidation at high temperatures. The nitrogen reacts with the air after the arc is electrically shocked, producing nitric oxide and starting to act as a protective agent.

Q: I have a 380V three-phase DC argon arc welding machine, can not be changed to 220V single-phase DC argon arc welding machine? Thanks for your help!: It's better not to change it. Transformer is a difficult problem

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

Q: Argon arc welding machine starting indicator light is not bright, fan turn is how, can not welding: Check the circuit

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.

Q: Argon arc welding machine on the ignition, note: switch is not bad, what is the matter?: The high frequency arcing part is out of order, mainly the high frequency arc starting control loop. So that it has no arc command (press the welding switch), the arc circuit has been connected.

Q: I bought an argon arc welding machine on the current, frequency, gas and so on how to adjust? Thanks: The current is according to what you want to use the welding materials, general material is thin, you need a smaller current; the frequency is not the duty ratio is? If it is to have a product object welding flaps only need the extension; gas is you press the torch switch, the gun will the "gas" as one sound, you open more, when you continue to end things after welding gun argon on longer, I personally think it is not recommended to switch too, is a waste, one is not too easy to play. Flint fire easily after the injury is not blowing material. You know there is no arc current machine, gas testing switch

Q: How to weld aluminum material with argon arc welding machine: No thorium tungsten or cerium tungsten welding steel pole with pure tungsten, alternating current, welding wire and base metal components. Similar aluminum heat quickly, the temperature of the base metal with the welding process in the continuous increase, to grasp the welding speed and wire feeding speed (generally with the welding process, to speed up the best lining pad. Flow) the welding pool of aluminum is not good, not easy to end with the best fusion butt welding arc plate and arc plate. Aluminum easy arcing, should pay attention to stopping.
