Q:How to use invert arc welding machine?: Note: when the first input line arc welding inverter is 220 volts if input is connected with a live wire, a zero line, if the input is 380 volts, is connected with 3 wire grounding, a yellow green color line welding machine shell and distribution box;At the same time, because the output of inverter welding machine for DC output, so that the output end of the wiring direction, normally welding positive line welding machine output, anode ground wire welding machine output, so called DCRP, is a common MIG welding normal connection; welding for DC output the electricity does not zero breaking arc, so not only can use the common acid electrodes, can also use the low hydrogen welding electrode and stainless steel and cast iron welding rod, the output current of more than 630 can also be used to make carbon arc gouging;The other is that when welding DC and AC is different can produce partial arc processing General in addition to changing the grounding position and change the electrode tilt direction to offset the blow, is slightly reduced in current, because the degree of current and magnetic blow is directly proportional to the square of the current, so slightly reduced, magnetic bias it may greatly improve the degree of blowing.

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.

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:Which is the best welding torch for argon arc welding machine?: No best, only suitable, unsuitable.Usually under 200A welding machine, welding current is not more than 100 amperes, lighter air cooling welding gun is adopted, the welding gun is light in weight and can reduce the labor intensity of welding personnel. Suitable for welding small current thin parts.Welding torch larger than 100A welding current and high power industrial tungsten arc welding torch. With more complex water-cooled welding torch, the loss of tungsten and other vulnerable parts can be reduced due to water cooling, and the arc column stability is stable. Suitable for welding heavy workpieces and high current continuous welding. The disadvantage is that the welding gun is bulky, increasing the labor intensity of welding personnel; the welding gun is more expensive; the water pressure must be up to the rated value before welding.

Q:What is the problem of inverter type hand arc welding machine without arcing?: Check the following possible: diode bad, circuit board bad, power supply phase missing, power supply insurance burned, the template is bad.Manual arc welding, referred to as hand arc welding, is a manual welding method that uses the heat produced by the arc to melt and welding electrodes.There are many health hazards in welding operations, which can be divided into two major categories: physical and chemical factors. The former has high temperature electric arc generated ultraviolet, infrared and so on. The latter is the various components of the welding aerosol, solid state has a variety of metals iron, manganese, aluminum, chromium, lead, nickel, radioactive elements, etc., the gas phase of manganese oxide, hydrogen fluoride, nitrogen oxides and other gases such as [1]. High temperature, vibration and noise are not obvious.The dispersion of welding aerosol is very high, and its biological activity is obviously higher than other dust. Welding electrode and welding method are different. The composition of the welding aerosol varies greatly, and the biological activity is also different. The biological activity of [2] is related to the solubility and freshness of the welding fume

Q:Argon arc welding machine why arc small, current is small, how can I solve?: You use or old-fashioned power rectifier argon arc welding bar, small current is auxiliary superimposed power supply, the main circuit of the electric output, which is not specific, and suddenly said it is not clear.

Q:Can argon arc welding machine be used as cutting machine?: No, it can be used as an electric welder. You want to make a cutting machine. Buy a plasma bar with that!

Q:What are the differences between an electric welder and an arc welder?: Lies in an AC dc. Arc welding can protect oxygen from inert gas. It can weld thinner construction.

Q:Why does the argon arc welding machine burn the black stick?: There are many reasons for tungsten burning:1, check and between tungsten argon arc welding torch position: clearance clamping with the clamping seat or between the gun body is too large, if it leads to poor conductivity, when in lighting, too close to the metal, the instantaneous current greatly, concentrated heat, not only will stick the needle, and will lead to loss; in addition, position is not correct, will lead to poor cooling, can also cause damage. So try to tighten the cap and check whether the tungsten electrode is reliably fixed. When purchasing, it is necessary to choose a closer clamping and clamping seat.2, check whether the standard AR (four 9 standard, namely the purity of argon must reach 99.99% or above), if the argon impure, cause of tungsten inadequate protection, easy burning; in addition to check whether the leak; one of the factors also affect the quality of tungsten.3, according to the welding machine AC and DC to correct wiring.(1) if it is a direct current welding machine, the ground wire is connected to the positive pole, the welding torch is connected to the negative pole; if the connection is reversed, the tungsten electrode is burnt out;(2) if AC and DC welding machines are used, the burning of tungsten will be more serious in the case of ac;

Q:Which is good for mould argon arc welding machine Ws and TIG?: WS and TIG are tungsten inert gas welding, welding die workpiece are generally relatively thick, suggest to buy machine output current of more than 400A, IGBT welding module, IGBT tube, field effect transistor (MOS) module, IGBT machine best but the price is high,IGBT single tube and field effect tube (MOS) prices are similar, cheaper, maintenance costs are low.
