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 uses computer to black screen
It should be possible to load a computer with a UPS
Q:Argon arc welding machine in use, the current becomes smaller, how to adjust there is no, the current is not big, what is the reason?
The experience is likely to be on the signal line shunt loose, or loss makes the feedback signal increases, resulting in reduced output control program, so how do you control are useless, do not recommend themselves Oh, to find someone to spend money, not a few. Code words are not easy. They want to be useful to you
Q:Can the inverter DC argon arc welding machine weld aluminum?
Not, recommend the use of hand straight wave current argon arc welding machine. Han Shen's WSME series, the effect is good, you can try
Q:What are the differences between invert DC hand arc welding machine ZX7-200T and ZX7-200?
ZX7-200T generally refers to the ZX7-200 shrink edition, that is, the internal Jerry built machine models, the actual output of less than 200A, only 160A or 140A, so the price is cheaper than ZX7-200!ZX7-200 general can reach 200A, but some black manufacturers also have the deficiency of power, shoddy!
Q:What is the function of an argon arc welding machine with current attenuation function?
Yours is a dual purpose welder. Is used to welding electrode, sometimes the current is small, welding rod is not good, arc will be sticky when. Adjust the thrust, the current is good, the arc started. To put it bluntly is to help lead the arc. Also in use, that is, vertical welding or overhead welding is to help the particles transition. Under normal circumstances, it doesn't help much. Generally do not open. You'd better not open the assembly to increase splash
Q:Argon arc welding machine does not arc, ground wire, welding torch is normal, what's the matter?
1: welding current is too small. Increase the welding current.2, the tungsten electrode burns badly, and the tungsten electrode is seriously oxidized, which leads to high resistance and difficult to arc. Regrinding tungsten electrode can be done.3, high frequency plate, high frequency ignition, discharge electrode burning, or serious oxidation, resulting in weak discharge. Use fine sandpaper to polish the electrode and replace the new electrode when necessary.4: welding machine in the high-frequency version of aging or damage. Check and trouble shooting, replace high frequency board when necessary.
Q:How does the argon arc welder overheat protection?
See if the fan is not good, use the compressed air to clean the dust inside the machine, the machine is overloaded, the power is too small (for power point welding machine or increase cooling capacity)
Q:Argon arc welding machine does not arc, and the surface of the welding brush contact reaction.
Looks like I'm a newbie, too
Q:Inverter type argon arc welding machine can not be welded without squeaking sound
The gun line of positive and negative power supply is broken.
