Q:Is there not a hot electric welding electrode holder? Which brand for a long time is not hot? Price and contact information!
We entered a batch of electric welding wang'er the day before yesterday, have not used, we see the factory in use this brand of pliers basically have replaced this seems to be good, we bought 75 yuan each, the dealer said later to have 5 pieces of money so that we use early.
Q:Electric welding electric welding hot is what reason
1: the holder of poor quality. Only to buy new premium holder.2: welding current is too large so beyond the rated load. Reduce the welding current; or the purchase of a large holder.3: welding tongs and cable not connected. Cable clamp and re tightened firmly.4: welding cable or welding line is not too thin; special cable; replacement of large diameter cables.5: welding cable socket or fastening screws loose, bad contact. Re tighten it.
Q:In welding, welding hot very much is going on? This way?
General cable clamp and poor contact resistance caused by too much. Methods: to ensure good contact with the cable holder!
Q:In the field of electric welding machine to clamp connection generally do not use what types of wire, or what type of commonly used wire
YH natural rubber sheath electric welding machine cableYHF chloroprene or other equivalent synthetic rubber elastomer sheath welder cable
Q:The wire for electric welder is connected to one end of the electrode holder, at least how many meters
There are standard, specific, I do not know, seems to be 5 meters.
Q:You need to apply grease holder CPU
Yes, it's the same as before
Q:An AC welder can receive the simultaneous use of two tongs
1, due to the common AC arc welder with temporary load rate is very low (below 30%), the two holder is not acceptable to use at the same time.2, AC welding machine is actually a special transformer, transformer is AC welding or welding transformer. Usually made into single-phase, cooling way for air self cooling, intermittent work, from no-load to short circuit, and from sister road to no-load, the load current changes rapidly.3, when welding arc circuit is in short circuit state, the voltage drop sharply, the current needs; to arc arc, this electrode and the pool containing solution or short circuit transition state, voltage or current is decreased; after the transition in the normal welding state, the voltage rise, the current decline.
Q:A hand holding a wire holder line will be charged.
Answer: danger!Reason: welding machine no-load (welding machine does not work) the voltage is about 70 volts, the safety voltage is 36 volts. If the holder, the grounding wire insulation is not good, it is easy to add in the hands of about 70 volts voltage, current will pass through the way hand -- hand -- heart the most likely to make them deadly.
Q:What kind of electric welding pliers? It's pure copper, durable
Brand new nice wang'er electric welding, especially the three generation power tongs, heating electrode, low wear resistance and fall
Q:What are the requirements for electric welding welder
Electric welding machine power bigger its thawing depth becomes deeper, conductive copper plate welding tongs must be copper, because the copper conductive function, copper to be thick, with a long time will not.
