100 watts is likely sufficient for a typical home machine, but you will have to check power requirements of the specific machine.

As to performance and software, if you operate the voltage converter beyond rated capacity, the machine will likely experience "brown out" or lost cycle power interrupt conditions and the resulting low power faults that occur with any embedded processor controlled equipment operating under poor power conditions.

Good rule is to use a converter rated at twice the maximum load equipment power requirements. It will increase the life of both the converter and load (sewing machine).

SOURCE: How many Watts does my machine have?

Watts is Current ( listed in Amps and normally shown on a tag of some sort on your machine ) times Voltage ( 120Vac) so if you had
For example.. if it listed 10A as in 10 amps @ 120 V then you would have 10 x 120 or 1200 watts.. This should get you in the ballpark.. If you can provide the exact model number of your machine.. I couold get the specs on it and give you a better answer.. Hope that helps...

SOURCE: sewing machine stops sews a minute slows down or stops then starts up

I suggest having the machine checked at a sewing machine shop
to see if there is something wrong with the motor, or the foot pedal
but first check to make sure the power cord & foot pedal are
connected correctly

SOURCE: Can sm1 plz help and tell me what watts brother HC1850 use cuz am tryin to buy a step down transformer for my sewing machine but I cnt find the watts it use.plz help

wats , or Power = I x E E= volts , if you unit shows the amperage that is I the voltage is 110 that is from the wall outlet, or 120
so 110 volts times your amperage, would = your wattage
if your product says 20 amp and you know your wall outlet has 120 volts then you will also know that you have 2200 wats

I have a singer 7422 sewing machine which is made in canada. I want to use it in india. So, what type of step down converter do i need and how much watt.


Hello Gargi Sarkar
The power supply voltage in India is between 220 V and 240 V. Your machine will be ruined if you plug it directly into the power supply in India. There are two options:
1. Use a step down adaptor to 'reduce' the 220 - 240 V to 110V which is what your machine can handle. This may be more practical and economical AND you can use the step-down adaptor for other Canadian electronics.
2. Your sewing machine motor can be changed for a 220 - 240 V motor, but often other parts will need to be changed as well. Also more costly.

Caan u pls help me I bought brother HC1850 from US and I live in Nigeria,in my excitement I didn't check to see what voltage it I Jst plugged it,it came for a second then give popping sound and then nothin...


If you're lucky only the power board is toasted. If it's bad luck then you'll have to replace both the power board and the main logic board. The good news is both parts together retail for under $100 US, so you should be able to find them on Aliexpress for a lot less. The bad news is the powerboard is not robust; if you want to use the Brother in Nigeria's 240V electrical environment I'd recommend using a 240v-120v step down transformer connected to a 120v UPS / Line Conditioner. Brother doesn't recommend that any of their computerized (sewing) equipment be used in poor power conditions or with step down transformers, the power circuits aren't built to be that strong.

Hai I bought kenmore before 2yrs .At that time I was in Us .Later in 2009 feb we shifted 2 India .Now I am living in Chennai,Tamil nadu.Because of volts problem unable 2 work here.What 2 do? should I get...


So your machine is designed and manufactured for 110 volts but India operates on 220 volta at 50 cycles per second. So you will need a voltage converter as well as a plug adapter.

There are three types of Voltage converters:

Resistor-network converters
This type of converter usually supports approximately 50 -1600 Watts. They are lightweight. You can easily use this converter for high-wattage electrical appliances like hair dryers and irons. But, you can use them for short periods only and they are not ideal for digital devices.

Transformers
Transformers support low watt rating, around 50 - 100 Watts. Generally, you can use them continuously. Also, they provide better electricity for low wattage appliances like battery chargers, radios, laptop computers, cameras, mp3 players and camcorders. Their drawback is the low wattage and heavy weight.

Combination converters
Combination converters are also manufactured by some companies. They are a combination of a resistor network and a transformer in the same package. You can easily switch between the two modes. If you need both types of converters, then it is better to buy this combination converter.

So you should check the model plate on your machine and see what the wattage it draws are to ensure you are using the corect type of converter.

Hello, My name is David.. I have moved to the uSA


No you cannot, the transformer will work for a while and it will get very hot and cound catch fire. You should get a transformer at least 100 W to 120 W. It can be an auto transformer which is not so bulky as an isolating transformer, but be careful how you wire it up.

Also have look on the machine it self to see how many watts in consumes. The number on the pedal may be the handling capacity of the pedal control.
