7. Master control board:The control circuit used one single master control board, it designed to be whole, and reduced connecting line greatly, fixed reliability, so avoided safe failure. This control circuit board is high degree of integration, the αangle automatic adjusted especially, that let power output of the equipment always was on constant condition, and electric power can be saved over 3% in comparison with same kind product. Safe start-up and automatic frequency-sweep.
8. Customer service: Free debugging (at home), all the costs of seller's experts go and work at abroad for return air tickets, accommodation and meals, will be borne by the buyer. The debugging ,the buyer shall compensate the experts at USD 150 per day for delaying time. The seller should be responsible for the scene testing; After normal melting the seller should be responsible to guarantee repair or change of the faulty components in 6 months, such as master control board,reaction,compensate capacitor,hydraulic device,breaker,and furnace shell (except for lining break through, stoppage or shortage of cooling water supply for components).
