According to spot welding wire diameter of different specifications and shapes of solder points, for select different welding tip.Welding tip is enameled wire welding in key components of paint removal and welding work, It consists of two parallel electrodes,  parallel electrode tip are made for constant resistance welding ohmic contact, according to the different welding wire diameter size and the different parts to process different shapes, and follows customer requirem.1, welding, please adjust the three sets of welding parameters, the attention is on the adjustment parameters, should follow the principles of regulating :small to large (universally adjust from initial values: 0.80v, 6.8ms, 12oz to increase, for reference only)Be careful to operate , make sure  head against the enameled wire and the parts in order  to ensure the welding quality and life.2.Forbidening empty solder, Otherwise it will burn out the welding tip 3.AS the different parts and enamelled wire line widths, Under the condition of normal use, usually each head can be welded 5000----50000 joints unequal. After using welding head if there have welding unreliability that we can increase the welding parameter, if the results are not good, you need to replace the spot welding 4.The welding tip clip according to the different requirements of welders, welding tip available with parallel type, L type and welding type
