The Power Cord On Your Sewing Machine by David Trumble
Before the dawn of electric motors, the sewing machine depended on human power. This usually took the form of foot or hand drive mechanisms.
The treadle sewing machine has been manufactured for over 150 years. Janome International continues to produce treadle sewing machines for third world settings lacking electricity. Those groups of people like Pennsylvanias Amish who prefer not to use electric powered sewing machines continue to seek this design. Many hundreds of sewing machine models were also manufactured using hand crank mechanisms.
In the early 1900s, the sewing machine exchanged the physical power for electrical power. Small electric motors were mounted next to the sewing machine and a belt drive replace the treadle belt and hand crank.
Electricity costs less today, you know, than it did so long ago. At least that is what the little bird said in the old ads for Edison Power And Electric. When it came to the sewing machine, it actually cost a bit more money than those old treadles, but it sure did save on human efforts. Sewing machines added electric motors that drew their power through a cord plugged into the wall. So easy! The United States used a 120 Volt AC system, while the Europeans used a 240 Volt AC system. The important thing is that the cord and motor match the power source. Otherwise, watch out for sparks, shocks, and smoke.
Accommodating the different power systems is fairly simple. You may purchase a power transformer to alter the power system to match the power required for your sewing machine. Plug the transformer into the power outlet and connect it to the sewing machine. If everything is in order, you are ready to sew.
It may seem a small thing, but the sewing machine power cord is a very important and delicate part of the sewing machine. Over time the sewing machine power cord may become worn. The insulation may crack or even brake away from the wire. The two wires may become exposed to each other creating a dangerous electrical problem. Not only can shorts or opens cause your sewing machine to fail and cease operating. Shock and electrical discharges can cause fires, ruin motors, destroy circuit boards, and generally mess everything up.
Be alert. You need have not fear, when you have prevented problems. Examine the power cord frequently. Feel it. Look at it. Flex it. Do you see any cracks? Does it have any cuts, or spots that are pinched? Does it have wires exposed. Are the prongs straight? Be proactive.
You may find spots on the cord that are not real bad, but could become a problem. There might be slight cuts, nicks, or cracks. You can fix these by wrapping them with electrical tape. Be sure that you wrap a little above and below the abrasion.
If you see cracks or an obvious break in the power cord, repair the cord by cutting the bad spot out of the power cord. Join only good ends by separating the two wires on each section. Make sure the insulation is intact. Attach the appropriate ends together. Remember you are working with AC voltage so as long as the wire is continuous after joining, they will work. You may solder the ends or use wire nuts to join the wire. Once the wires are joined, cover the joint with electricians tape thoroughly to prevent further wear.
If the cord is badly worn, replace it. Do not continue using faulty sewing machine power cords. In most cases, you can install a new power cord without replacing the foot control. Yes, many cords do attach to the foot control, but the foot control may be disassembled and the ends of the new cord installed.
If you power cord is faulty, replace it. Check with you local independent sewing machine dealer or a wholesale parts dealer like Tacony Corporation for availability. Older cords will probably need to be replaced with aftermarket new ones. The foot pedal can also be replaced, but if it is older, you may need to opt for a generic foot control.
Caution: Fix or replace bad power cords. Save you home and your life.
