Technical Parameters

Q: How do I get the power from 380V?: 380V-0V-220V means can use BX6-315 AC arc welder 380V and 200V, as long as you in the 0 terminals and 380 terminals connected to 380V power supply can be used, such as some places without 380V power on the 0 terminals and 220 terminals that can also access 220V power, saying simply is BX6-315 AC arc welder is AC arc welder with 220V tap

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?: Hello, ground wire and ground wire, grounding wire to prevent leakage from the welder shell to the earth line, safety protection. The wire or workpiece line is used to form an arc circuit with the welding torch

Q: What effect the quality of Andre micro argon arc welding machine?: The quality is very good! I bought it for more than two years and it's still good to use. It's the same as the new one.

Q: High frequency is normal (between two points of spark is not small), arc can also be wiped, the current is not small (adjustable). It is difficult to start the arc.: That is, there is something wrong with your needle. Some of the machines are just the beginning of the time. The current is unstable and the current is steady

Q: The normal function of argon arc welding welding, arc not normal, press the switch can hear the fire place in the machine (what is I do not know the name, like the discharge gap? Is the two small pieces of metal plate - like contact not contact place) with loud no problem before, there are sparks. Some people say that the problem is the high frequency don't ask the master, the arc, which is the problem, can repair? Is worth repairing? Can not repair welding repair in our county those people say. Thank god!: The problem is one of several 12V relays on the circuit board. After the power is switched on, the switch of the gun is pressed, and it is known by the multimeter.

Q: Common faults and maintenance methods of DC invert manual arc welding machineWho has the relevant circuit diagram?For example, the market style: ZX7-200, MMA-160, ARC-200 and other modelsWhat does the letter "ZX7 MMA ARC" mean?Are they all invert DC manual arc welding machines?: ARC is the meaning of identifying arc weldingMMA manual metal arc manual metal arc, that is, electrode arc weldingInverter welding machine with ZX7 DC down characteristic

Q: When argon welding machine welding aluminum, how to set?: Welding aluminum must be exchanged unless the edges are polished by direct current welding

Q: Mainly used for welding stainless steel anti-theft network, doors and windows can be portable, please say specific parameters, brands, and the approximate price! Thank you. The answer is satisfactory!: Small machine Ruiling okay, but is the MOS tube (these are civilian level), with a feeling of not less than IBGT arc stiffness.Inverter welding machine is light and energy-saving. But not as durable as wire packs.Buy welding machine mainly see temporary load duration, general, but 60%, if the target is small, indicating that it is smaller than similar power. (if the manufacturer is not blind.).The price of MOS tubes should be around 1000.

Q: How much electricity does an argon arc welding machine use in a day?: 315 welding machine 12KW, 400 welding machine 15kw., this is full load when the power, output current is different, the total power consumption is different, and welding always has a pause, so the power consumption is uncertain!

Q: WSM-200A inverter DC pulse argon arc welding machine access voltage, what parts of the assembly damage?: Wsm-200's machine is 220V, and if you receive 380V, usually burn the insurance first, and if you don't burn the filter, the filter capacitor is the first one to go wrong, and the most wrong power I've got is the capacitor.
