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: 220V welding machine is common (or 380 power) if I put it with a positive line divided into 2 with two words two tongs holder can also work with voltage afford it

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 step-down transformer, AC welding transformer, or called "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: An AC welder can receive the simultaneous use of two tongs

Yes, but at the same time work will be much less current, very bad to use, it is best not to use two.

Q: What is the 500A electric welding welder

Yes, electricity welding machines are available

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!

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 what method

So the quality of the market is the holder of iron copper resistance, heat resistance, so too large. Do not remind you of copper core holder, because copper is too soft, not several times will be too large jaw not live clip electrode, the market is clamoring for a copper holder is a lie. Do the holder must use special brass, brass hardness and wear resistance, and conductivity are suitable for welding. Should buy a real casting brass tongs.

Q: How to configure the welding line of electric welding machine

According to the power of the welder, there are usually 35 square and 50 square lines.Electric welding machine cable (YH cable) full name high strength rubber sleeve electric welding machine cable, commonly known as welding wire, is YC cable (Universal rubber sleeve cable) one kind. Specifications of the model has 16 square, 25 square, 35 square, 50 square, 70 square, 95 square, 120 square, etc..The structure of the cable for the welder is single wire core, usually composed of copper wires and copper wires. The group of copper wires make up the conductor part of the welding machine cable, so the YH cable is thicker and hundreds of copper wires. A plurality of groups of copper wires are wrapped around a layer of heat-resistant polyester film. The insulating layer is pure natural rubber and the copper wire is oxygen free copper, so as to ensure the good conductivity of the wire core and the safety of the cable.

Q: Who knows the welder wireless holder?

Still to be invented later.
