I have a Viking 630. What numbers should the tension dial be on so the top thread does not show on the bottom when the bottom thread is a different color from the top thread.


There is no really correct or wrong answer here. It's trial and error, and experience with your machine. The reason? WAY too many fabrics and variations on threads. The wear in the tensioners and even the needle all make a difference. When in doubt, start with everything set in the middle of the range and test a few runs.

Stitches to loose


You need to tighten the bottom and top stitches both. First, tighten the bobbin slightly. Now, tighten the top stitches the same amount of pressure as the bobbin. The attempt is to have both the bottom and top stitches exactly the same so the final stitch ends up in the center of the fabric. Observe the stitch and readjust if necessary.

Can't get tension right have adjusted tension dial but when you pull the thread it just pulls out like tacking stitch


make sure that it is threaded correctly between the tension plates
correct tension is when you pull the thread as if to thread the needle there should be a slight resistance to you pulling the thread

Upside down stitching


Am having a difficult time picturing this. Sounds like the upper thread is creating loops under the fabric and the bobbin thread is showing on the top of the fabric.

Make sure to use a brand new needle.

Remove the thread from the machine
ALWAYS raise the presser foot and rethread the upper thread.
Make sure the thread path is correct.

Check that the bobbin is turning the correct direction in the bobbin case and the bobbin thread is threaded through the bobbin tension correctly.

Set the upper tension to the midway point (factory standard), however, this setting may need to be tweaked for your particular machine.

Bring the bobbin to the top of the project Before beginning to stitch.
How and Why to Bring up the Bobbin Thread

Retest--begin sewing slowly.

If the upper thread is still showing on the other side of the fabric, the tension is too loose. If it is pulling the bobbin thread up to the top of the fabric, the upper tension is too tight

OR the bobbin thread tension is too loose. (CAUTION: make only small adjustments to bobbin tension--1/8 of a turn at a time!!! It also helps to mark the screw groove location with magic marker on the bobbin case BEFORE making any changes so you can back it out and return to the original setting.)

How to adjust tension?


Consult the owner's manual. Be sure to always RAISE the presser foot when threading the upper thread.

Test the stitch. If the thread is looping under the fabric, the upper thread tension is too loose. If the bottom thread shows on the top of the fabric, the upper tension is too tight. The tension is correct when the two threads (top & bobbin) meet in the middle of the fabric.

NOTE: when you change needle/thread/fabric, the tension should be tested on a piece of the project's scrap fabric and readjusted before beginning the project. Tension is static and should be adjusted every time a project is changed. (One tension will not work for every project, so get comfortable with tweaking.) Be sure to change needles frequently (damaged needles are an inexpensive fix for a lot of sewing issues). Making sure needle/thread/fabric are compatible is very important. All About Needles

I can not get the tension right - the manual is not helpful at all - please help?


Be sure to RAISE the presser foot BEFORE threading the upper tension. This releases the tension disks so the thread will seat properly.

Start out with the upper tension set at the mid-point. This is generally the factory setting. Then test and adjust. If the thread shows loops under the fabric, the upper tension is too loose. If the bobbin thread is showing on the top of the fabric, the upper tension is too tight. Test and adjust until the top and bottom threads meet in the middle of the fabric.

Bottom thread seems too tight!!! Help!!!


If the bottom thread is tight there should also be loops on top and this means that the upper tension is too tight.
Get out your manual (http://www.singerco.com/uploads/download/1198_8763-efs.pdf) and turn to page 24. Under "ADJUSTING TOP THREAD TENSION" it tells you that if you're having thread tension issues, change the tension control dial on the top of your machine from auto. It also shows you a diagram with your problem illustrated on the right side of the page. The bobbin tension is set at the factory, so all tension problems can be solved with top tension adjustment. Set it manually and if it loops on top, loosen the tension a little. Test again. Repeat until loops are gone.
Using different colours on top and bobbin and a contrasting fabric (e.g. black top, white bottom, light blue fabric) means you can easily see what's happening. A perfect stitch is when you see exactly the same stitch pattern on both sides of the fabric. On top, the bobbin thread colour appears between stitches as a tiny dot and on the bottom, you see the top thread dot between stitches.
If it's impossible to get the tension right, take it to a technician, because it's a sign that the hook timing needs attention.

Adjust tension


The tension of the top thread and bobbin thread are in a "tug of war". If the top is "winning" or too high then the bottom thread will be showing on the top of the fabric. If the top is "loosing" or too loose then the top thread will be pulled through the fabric and show a lot on the bottom. They must be evened out so the "tug of war" is even so the knot is in the middle of the fabric.
START WITH BOBBIN FIRST: Remove bobbin and bob from finger. When you have it adjusted right then the bobbin will extend one inch when you bob it. If you can't bob your bobbin you will have to make an approximate and replace. You may have to do this a couple times to get it right.
WHEN IT'S RIGHT: The bobbin and top tension are equal without being too much pull on both that causes the fabric to pull together.

The bottom side of the item I am embroidering is showing all of the top thread color. I have adjusted the tension dial and bobbin tension. Any other suggestions?


Normally you will see the about 1/3 bobbin thread and about 2/3 of the top thread on the bottom side of the fabric. If you dont see any of the bobbin thread on the back side turn the upper tension (needle tension) to a larger number.
Good Luck,
Doug

How do I adjust tension top thread too tight bottom


The bottom tension is too loose. If your bobbin is in a case there is a little screw on the side that will tighten the plates and increase the tension. Test your thread coming out of the case as you slowly make adjustments to the screw. A slight bit of resistance is what you want. If your sewing still puckers you may have to loosen the tension on the top. Sew on a scrap and go toward the smaller numbers to loosen the top tension until the stitches meet between the two layers of fabric.
