Name and method of assembly
Point to be checker before use
• The center of Upper and Lower electrodes needs to be in line within 0.5mm and make sure not to be angled. If electrodes are misaligned more than 1 mm, it may cause a misalignment of nut.
• Check the condition of electrode cooling. There are possibilities of loss of Nut Checker and poor insulation due to burn out of insulator or O ring.
• Check if outside diameter of upper electrode is within +0.1 -0mm of Nut Checker size. If the diameter is bigger, it is difficult to assemble Nut Checker which may cause a loss of Nut Checker. (It is also possible to manufacture Nut Checker to meet the used electrode size. Please consult with us.)
