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

Generally requires construction within 30 meters. 100A with less than 25 square millimeter of copper wire, 200A~300A current with 35 square millimeter copper core wire, 300~400A current with 50 square millimeter copper core wire.

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

According to the power of your welding machine

Q:In welding, welding hot very much is going on? This way?

With the cable holder or poor contact with the electrode contact, the former can be screwed or welded, the latter may be holders and contact between the electrode plate can not change it.

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

Not because of the design of electric welding machine is selected and the linear size are required if you divided into two holder words is not only a challenge to the line, he the power factor is also a challenge because the power factor of electric welding machine originally is very low

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:Electric welding electric welding hot what method

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:What kind of electric welding pliers? It's pure copper, durable

Elephant brand?! The clamping force of pure copper is good enough and the component holder, good workmanship can also on-line. Our factory has been using this, it changed a lot of brands have been eliminated by us!

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.
