We have finally received an answer from ETS, the supplier of the Melting Machine.
It could not be fixed, please see below. I have also asked if we could sell our machine for parts but ETS do not want it.
We would like to replace the machine with similar one in the market.
The melting machine is used to melt metal scraps for refinery instead of manually heating with a torch. We run this process about 23 times per week.
It is also used for melting / making metal bars to make findings and wires.
The melting machine saves 50% of the time comparing to the torch but most importantly it is safe and clean, plus metal loss is minimum.
A new machine will cost roughly $10,000.
