Please help -- machine blowing fuses! Recently i just bought a letterpress machine from USA. The electrical requirement of the machine is as follow: 1) 115V 2) 2.6A As i am living in singapore which has a different voltage, i bought a transformer to step down Singapore's 240V to 110V, which close to the US voltage. The tansformer model i bought is ST 500. Which is able to give 2 output voltage, 110V and 220 V. when i on the letterpress machine, the transformer fuse burnt instantly. i had alrdy tried with 3A and 4A ampere fuse, but it all burnt instantly after on the machine. Please advise on the value of ampere fuse i should use. Million thank!!!!!!!!
