Which of the following is true about shielded metal arc welding? Correct Answer cannot be used for metal sheets under 1.5mm thickness

The following are some advantages of shielded metal arc welding : (i)low equipment cost, (ii)welds many different metals, (iii)welds can be performed in any position, (iv)process less affected by wind, (v)can be performed under most weather conditions. SomeThe disadvantages are : (i)not suitable for metal sheets under 1.5mm thickness,(ii) entire electrode cannot be used, about 25-50mm electrode is wasted.
