Q: A hand holding a wire holder line will be charged.: Dry environment, dry palms will not be the case.

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: 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: Have positive and negative electric welding machine, electric welding pliers with which side up to the: There are positive and negative output points of the machine, the machine is said: DC welding machine;You mentioned the pliers, you can determine which is a DC arc welder;Want to know the DC hand arc welding machine, which output head ground wire, which output first welding line, please look down;When welding operation, there were two kinds of connection method: straight connection method and reverse connection method two kinds;Positive welding - welding workpiece welding machine output power positive electrode, welding rod welding machine output power negative electrode wiring method, also called positive polarity.Reverse connection - welding workpiece, welding machine output power negative pole, welding rod welding machine output power positive pole wiring method, also called reverse polarity.Generally speaking, the principle of polarity is used:Reverse welding is used for basic electrode welding;Because the basic electrode welding by hand welding, arc combustion instability, splash, arc sound is very hot, and easy to produce porosity. When using reverse connection, arc combustion is stable, splash is small, and the sound is even and even.The positive welding method is adopted for the manual welding of acid welding rod;The welding pool is deep welded by the positive welding method. The weld seam is narrow and the welding height is high;Reverse welding, welding, welding pool shallow, weld width, Han Duiping (short);Connect / reverse connection does not affect the function, only affect the welding effect;For occasions where the requirements are not high, some welders try both positive and negative, and it is good to try them at ease;

Q: You need to apply grease holder CPU: No, in addition to the high temperature CPU and graphics card and radiator need direct contact cooling with other grease by accelerating natural cooling on it

Q: Is there not a hot electric welding electrode holder? Which brand for a long time is not hot? Price and contact information!: The three generation of welding tongs - million in hand you worry, we also know that, when started in February to buy

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: 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: 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.

Q: Who knows the welder wireless holder?: There's no way. The current is too great
