I am in the USA Ray.B
I seen a guy (Richard UK ) having some solder stuck in his new Hakko FR-300 in the UK. His website was on You Tube "We Conclude the Hakko FR-300 and put it to rest," "Richard UK". He also had a previous You Tube video on his Hakko FR-300 before this one. I mentioned to him that he should have sent the Hakko in for repairs which was under warranty. You have to watch the video and shudder.
Richard said that he measured the mains voltage at his area and it was 240 Volts, the Hakko FR-300 was set to 220 Volts on the board that he had. I was wondering if the difference in voltages would cause the resistor to arched over. Richard also said that he was having trouble trying to clear out a solder blockage in his Hakko FR-300 and overstressed the motor. He was very mad about the problems he was having with his 300 dollar learning experience. He probably can't get his Hakko repaired because of all the damage he did, but he could replace the PWB, the board is listed under B5012 for the 220-230 Volt version and a B5013 for the 240 Volt version. I don't know the differences, and probably the 220 Volt version is the only one the UK is authorized to use, even though he has 240 Volts in his area. He also was asking about the motor, he could power it up with 35 Volts AC on the leads to see if it worked, ( the motor is the only thing that Hakko won't replace, only internally.) (In my post I mentioned that he could use a isolation transformer and variac to test it.) Richards topic was about six months old. Later Ray.B
