How many workpieces will be mercilessly ruined before a novice welder masters the art of thin metal welding? One careless movement and now a thin part is already perforated with an electrode! Few can learn how to cook thin products at a snap. Therefore, if you take up a welding machine, it will not be superfluous to remember about three relatively simple and very effective methods.
Method one - return
The essence of this method is to drive the tip of the electrode with a constant return. To do this, markings are made along the entire length of the future seam: risks are applied with a step of 5 mm. Once the boil has started, the electrode is pushed forward to the next mark each time enough metal has been deposited. After applying the first seam, you can make another one, completely repeating the boiling mechanics described above.
Method two - straight
The fastest and most efficient way to melt thin metal. The heated electrode is brought to the joint of the parts so that the tip remains at the holder. To obtain a wide seam, the electrode is gently guided along a wave-like path. In this case, before starting to cook, you must first make sure that the welding machine (current strength) has been adjusted to the current metal thickness.
Method three - separation
This method is generally similar in its implementation to the one that has already been described above. The work with the electrode is performed in the same way, with the only difference that the hot equipment necessarily comes off the seam for one instant every 0.5-1 cm. The seemingly insignificant pause actually allows the metal to cool down. The critical temperature drops sharply and no further burning occurs. For novice welders, this method is perhaps the most optimal. At the same time, the pauses should not be too long.
