Pack of 2,5 kg steel welding basic electrodes

Steel welding electrodes in practical blister packs.
The special coating on the electrodes gives it an excellent basic material depuration capacity which leads to top quality welding operations that guarantee significant mechanical sturdiness.
Moreover, these electrodes do not contaminate the pool with hydrogen.
The fluorite content in the coating makes the arc less stable and the pool less fluid; the arc must therefore be kept very short due to the low level of volatility of the coating itself; this mean the welders need to be very experienced in such operations.
The slag produced can be very hard and difficult to remove; it must however be removed if it is necessary to repeat the operation.
These electrodes are ideal for welding in vertical or overhead positions and welding must be performed using Inverted Polarity continuous current (positive with electrode holder clamp).
