Question:

Welding 1.2 plate should be used in what diameter of the electrode and the current strength?

Welding 1.2 plate should be used in what diameter of the electrode and the current strength?

Answer:

Welding 1.2 mm sheet, electrode diameter and current strength and other parameters are as follows:    ZX7 inverter DC welding machine (with the characteristics of arc stability, compared to the welding machine is more suitable for thin pieces of welding), the use of reverse (ground clamp negative pole, welding clamp positive +) polarity.    Electrode: 2.5 mm in diameter (the market is relatively easy to buy, theoretically diameter 2.0 electrode is difficult to buy to, and the price is much more uneconomical), welding current between 65-75 amps.    Welding methods and precautions: the electrode as far as possible tilt angle (to avoid the arc blowing on the formation of 1.2 plate burning), the use of rapid spot welding (arc welding), can not even arc welding, or will burn. With a cap to observe the molten pool cooled to less than the welding rod diameter re-arc welding.

Under normal circumstances, certainly with the 2.0 electrode, welding current in 50 ~ 60A on it. You try, should be no problem, 1.2mm has enough thickness! Do you have a small welder? We specialize in producing welding machine.

Theory is feasible, First say, where to buy special welding electrodes. 1.0mm of 1.2mm. Have to find a good current transfer of the welding machine, have to be able to arc. General welding machine, or no-load voltage is high, can lead arc, but the current tune is not small, or adjust the small instability, short arc. Or is a small stability, but no-load voltage is also followed by low, bad arc.
