You just need a step up transformator. It is available on the market

    That's fine but changing the Power Supply Unit is risky because you might have to change other electrical parts too, copy lamp and fuser lamp must be changed to 110 V but i'm not certain if you have to change any of PWB boards.

Miller trailblazer 302 it has 110 volts but no 220 volts


Both sets of the 120? If both of those are there (all 4 outlets), then the machine is producing 220v. So get a flashlight and look into the holes on the 220 receptacle, or check the wires on the backside of the receptacle. All that 220 is, is two 120 volts out of phase.

I bought a machine from the US last week with 110V specifications and used a step down converter for use in Pakistan which has 220V specifications. When plugged in and turned on, there was a pop sound...


It sounds like something blew in a big way. Likely to be the main power supply board. The step down transformer should have reduced it to the 110 volts you require. Check the transformer to make sure it does actually reduce from 220 to 110 vac. Also check the hertz , (hz) ( cycles) Australia uses 50 hz at 240 volts ac. im unsure what hz USA or Pakistan is. Confirm your transformer output meets the electrical specification of the coffee machine. There may be a local Nespresso machine repairer who will convert yoru USA spec machine to Pakistan voltage thus negating the need for a transformer. It may be a bit expensive replacing all the electrical comonents though, it may still be worthwhile.

I have philips hts8100 from usa , can I plug it in 220 volts or 110 volts


The Philips HTS8100 is designed to use 120 Volts AC. You could use a 220 Volt AC to 120 Volt AC Step Down transformer to power this using a 220 Volt outlet. Here is what you will need:

Will it be okay to connect a 110 volt laptop to a 220 volt LCD projector?


What voltage is your mains supply?
The laptop's adapter should be a multi-voltage type 110 to 240 volts input.
If your mains is 110 volts AC then the 220 volt AC LCD projector won't work unless you connect it to a step up transformer (110 to 220 volt transformer).
If your mains supply is 220 or 240 volts then both the laptop and the LCD projector will work without any problems.

What is the polarity and voltage setting for the hot water on demand system


Well if you buy a 220 system it will be 220 volts.
All the bigger systems like for whole house will be 220.
some smaller under sink models will be 110.
There is no polarity since it is AC. If you find something that says polarity on a on demand water heater then somebody at the factory is smoking something.
110 has 3 wires. all tests need done with a multimeter on the AC setting.
Black wire will be 110 volts AC, White wire is neutral and green wire is ground.
220 system also has 3 wires. Colors can vary a bit here but usually it goes like this.
Red wire is 110 AC - Black wire is 110 AC and white wire is Neutral or ground.
Test to ground they read 110 Volts AC test to each other they read 220 AC because they are out of Phase to each other.
PLEASE note. Always get a certified electrician to work on these units. If you feel you are just as good as any electrician, please make sure you have a family member nearby with a phone that can dial 911. 110AC can kill you and 220 AC can kill you faster and deader.

To know whether any particular unit is 110 or 220 we would have to have the model number to look it up. Some can be either and in this case the only way to know is to take the junction box apart. If it is just plugging into a regular wall outlet then it is 110. If it looks like a special plug or like a dryer plug then it is 220.
Hope that helps. Have a great weekend.
