I、Maintenance of the die type 1 and type 2

Each set of die consists of 4 blocks(two A blocks and two B blocks),6 pins and 4 pieces of springs. The size of block A and block B are different and the same sized blocks are diagonally aligned, as indicated in figure 1.Notice:There is no letter "A"or"B"on the real blocks.

The die must be cleaned if the parent wires can not be effectively welded after aperiod of application. The cleaning details are as follows:

1.Take out the die from the welder with the driver.Be careful of the springs to avoid scattering.Rub every faces of the blocks with a piece of clean cloth,esprcially wiping away the metal particles,Remove the lubricant completely welded because of sliding mocement.

2.Match one block A and one block B with springs and pins between the two blocks and hold them with fingers.Assenble another block A and block B with the same method.

3.Match the above four blocks with spring-precoated pins. Pinch the four blocks with fingers to test their movement.There will be no abnormal obstruction on the mocement if the four blocks are perfectly matched.

4.Hold the four assembled blocks with the die driver or insert them into the welder.

II、Maintenance of the die type 3

Each set of die consists of 4 blocks,2 long pins and short pins,as indicated in figure 3.
Disassemble the die if necessary and rub every faces whith a piece of clean cloth ,especially wiping away the metal particles.Assembling of the diw can be easily accomplished by aliging the blocks according to the original numbe mark and the instaling the pins to hold .

III、if the die will be idle temporarily,lubricate and keep it in the die box to avoid rusting.Remove the bubricant in the wire groove before the die id used again.
