Answer: welding, melting portion of the mother material in the weld metal in proportion.

Answer: welding, the welding heat source is input to the unit length of weld heat input energy, also known as the "".General use J / cm (J / cm) said.

Answer: welding, welding wire end from the tip end of the distance.

Answer: unit time to complete the weld length, generally with the cm / min (cm / min) said.

Answer: the arc ends (two electrodes) between the voltage drop, generally use volts (V) said.

Answer: when welding, the welding current flowing through the loop, generally with the ampere (A) said.

Answer: when welding, the welding quality is ensured and the selected various physical quantities (such as: the welding current, arc voltage, welding speed, energy etc.).

Answer: wire melting coefficient is the unit of unit current wire melting rate.(g / Ah)Wire finer and finer, the melting coefficient is bigger, the higher the efficiency of both.
