Q:The argon arc welding machine doesn't adjust the current. Is there a problem?
Or adjustment switch is a problem, and then either 380 of the welding machine connected to 220 of the power supply, and the last case, high voltage package problems.
Q:Beacon TIG-160 argon arc welding machine is difficult to cause arc, all other normal, who can help me point out?
There may be tungsten or card to the heart is not good, with sandpaper tungsten surface slowly, check whether the replacement of the heart,
Q:How can the argon arc welding machine adjust the operating voltage range?
When the argon welder is constant current, the operating voltage varies with the operating current, and no adjustment is needed. If the work voltage is changed forcibly, the welding machine will not work properly
Q:Argon arc welding is the best brand of that brand.
Can think of Taobao to buy electric welding machine, that is, the convenience of the map, the so-called brand of good welding machine, there is a rangeIf it is a professional welding work, factory level, most of them will not recommend the use of Taobao, several hundred thousand yuan under the welding machineBut that being said, not to say that Taobao's small portable welding machine can not buy, think of cost-effectiveIf you just weld, or remodel an iron flower rack, use it at home and buy a small, hundreds of dollars welding machineOr, as a professional welding learning, you can buy a try a hand,Taobao welding machine. Purchasing experienceSingle edition (single chip circuit) welding machine. This kind of big manufacturers of goods more stableMulti plate welding machine, front and rear, up and down the separation of the plate composed of. Better structure. Good heat dissipation. Easy maintenanceIf you buy the brand in the brand name, do not buy the first, try to choose the welding machine with multi plate structure,Moreover, the power and output of Taobao multi welding machine are virtualIf you really want to buy a portable, single edition, try to buy a larger brandIf you don't consider is inferior.
Q:That type of inverter, pulse argon arc welding machine is easy to use
It is made in China and has poor exhaust molding and high failure rate.
Q:Can the invert manual welder be argon arc welding machine?
I am a professional engaged in welding machine R & D. Tell you exactly: no!
Q:Should the DC arc welding machine be equipped with electricity saving, shock proof and leakage protector?
In principle, all electrical appliances need to install anti electric leakage switches (especially metal shells, electrical equipment) at the power input terminals, and the same with the welder.If the anti welding output of electric shock, you don't have to worry about this, on the market in the sale of the DC welder basically has the electric shock prevention function (VRD), the anti shock function after opening, the welding output load is generally not higher than 20V, two hands and two are positive and negative contact welding output terminal, there will not be any shock feel very safe. You can buy Welding machines with this function.As far as energy saving is concerned, it is only when the electric welding machine does not work for a long time, turn off the power supply to save electricity. Now with the inverter DC welding machine, transformer AC welding machine compared to old-fashioned, no-load loss is much smaller, if only a short period of time without welding, no need to put what sort of economizer, if it is a long time without welding, mind you directly off the welding machine.
Q:What's the equivalent of 17KVA's AC arc welder?
1KVA is not equal to 1KW, but also multiplied by his power factor, domestic is generally 0.8, said only 13.6KW. Plus no-load and sometimes voltage fluctuations are basically 14KW
Q:Argon arc welding machine sometimes cannot cause arc, why?
First, it may be too high or too weak or high frequency! Second, tungsten quality is poor, third welding torch copper wire open!
Q:Who used the three Joe brand argon arc welding machine? What's the quality?
Now for personal use, cheap machine, 1000~2000, 60% "general election" reallink machineOther brands of machines, if they haven't heard the name at all, are not,Only nominal 200A may actually be 180A, can use 5 years can use 2 years, is the copper wire all changed to aluminum...The cost is greatly reducedBut when you change, you just throw it out
