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: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

The standard is not too long, but in actual use, there are usually 10 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:Have positive and negative electric welding machine, electric welding pliers with which side up to the

Fine！ The manufacturer's instructions are mostly negative!

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:Who knows the welder wireless holder?

Still to be invented later.

Q:An AC welder can receive the simultaneous use of two tongs

The arc is difficult to produce and the welding current is unstable. I tried

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: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.
