Q:How to use the arc welding machine?
Aluminum can focus on argon arc welding argon arc welding of Odin Wei, Wei Odin have special customer service and debugging
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:What do you mean by "WS.TIG.ZX7." on argon arc welding machine? What are the characteristics of each?
ZX7-*** inverter direct current welder:Z denotes DC (arc welding rectifier)X indicates the drop characteristic (the instant arc voltage is about 70 volts, the arc is successful and the welding voltage drops rapidly to about 30 volts.)7 represents inverter type, including third generation inversion of MOS field effect tube, IGBT (IGBT single tube, IGBT module), fourth generation inverter.
Q:What about the current of argon arc welding machine is too small?
Argon arc welding welding current adjusting welding current of TIG welding is usually chosen according to the space position of the workpiece material, thickness and joint, when the welding current is added, the penetration depth increases, the weld bead width and height increased slightly, but little increase, the welding current is too large or too small will cause the poor weld shape or welding defects, the position of the welding current to 80 ~ 110A is better, the ideal current value is 90A, when the spot welding current to 150 ~ 180A is better, the ideal current value is 160A.
Q:How can argon welding be used to weld copper material? What do you need to have? Is the argon arc welding machine OK?
Gas welding speed is relatively good brass, molding difficult aspect. Red copper or nickel copper alloy can be welded by argon arc. Welding wire is right. No brass welding wire can be used.
Q:AC and DC pulse square wave argon arc welding machine operation method?
If the black needle tune too close to the outside, a welding is easy to stick, the Ukrainian needle transferred to the porcelain mouth inside 1-2 mm, and then welding will not stick, and welding out of the effect is better.Argon arc welding argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form molten pool, the metal to be welded and the welding material to a welding technology of metallurgical combination, also known as argon gas shielded arc welding. Argon arc welding is divided into two kinds of argon arc welding and non melting argon arc welding according to the different electrodes. Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form molten pool, the metal to be welded and the welding material to a welding technology of metallurgical bonding, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.
Q:What gas does argon arc welding machine use?
Argon gas arc welding machine, the most commonly used inert gas is argon. It is colorless and odorless. The air content is 0.935% (by volume), the boiling point of argon 186 C between boiling point between oxygen and helium. Argon is a by-product of oxygen production by liquid oxygen from an oxygen plant.Bottled argon is used for welding in China and the filling pressure is 15MPa at room temperature. The cylinder is painted with gray paint and marked "argon". The chemical composition of pure argon requirements: Ar = 99.99%; He = 0.01%; O2 = 0.0015%; H2 = 0.0005%; the total amount of carbon less than 0.001%; the water is less than or equal to 30mg/m3.Argon is an ideal protective gas density than air in 25%, is conducive to the protection of welding arc welding, reduce the consumption of protective gas. Argon is a chemically inert gas that does not react with metals even at high temperatures, without alloy oxidation, burning, and a range of problems. Argon is also insoluble in liquid metals and hence does not cause pores. Argon is a monatomic gas that exists in an atomic state and has no molecular decomposition or atomic absorption at high temperature. The specific heat and heat conduction capacity of argon are small, that is to say, the amount of absorption is small, the heat to the outside is less, the heat in the arc is not easy to dissipate, the welding arc is stable and the heat concentration is concentrated, which is beneficial to the welding.The disadvantage of argon is that the ionization potential is higher. When the arc space is full of argon, the arc ignition is difficult, but once the arc is ignited, it is very stable.
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:The difference between AC argon arc welding machine and DC welder
The difference lies in the use of different welding and argon arc welding machine with gas tank, and DC welder need only electrical and conventional electrodes. Argon arc welding of metal material processing is very thin, and DC welding processing thickness less than 3MM material processing inconvenience. TIG welding wire electrode is disc type electrode. The different DC welder.
Q:What parameters should we pay attention to when purchasing argon arc welding machine?
The first statement I am not manufacturers, 160/200A can meet the requirements of the brand, United is good, price is a little expensive, good quality and less maintenance, reduce the time you spend a lot of money is to buy the machine, but also made. Please forgive me, but the price is really unknown now.
