SOURCE: Weld arc not stable. Wire feeds, good ground,

Try moving the tip closer to your work and try turning your wire speed down
Most people want to crank up the wire speed when it spits and sputters
Turn it down
See if this helps

Arc blow could be the cause! Put your ground on the work piece and weld away from it. If you weld toward a ground clamp the magnetic forces will blow your arc around sometime. When taking a cert this simple mistake can make or break ya on your cap or reinforcement beads.

I have a Lincoln wirematic 250 when I weld it will run fine but once in a while it will pulse the ark in the weld. And is doing it more often. Stoping me from running a continuous bead.

indicates the following problems
rusty wire in use-- the rust builds up in the inner wire and will not allow free movement
the inner cable is worn and is grabbing the wire in a groove -- the inner cable will wear a groove and that catches the wire in certain situations --
the feed rollers are worn or the wire in use is not correct for the groove in use
most feed rollers have 2 grooves and each one is for set dia wire there are different rollers if gasless wire is in use to prevent the wire from deforming as it passes through the rollers

Burns wire off at feed rollers When begging to

You are missing the inlet or the outlet wire guide, these parts will help to insulate the wire from ground. What's the brand and model of your machine???

I have a weldmark 140. When you turn the voltage knob it controls the wire speed. The wire speed knob does nothing

Flip up the cover on the side to expose the welding wire rool.
push the feed button on your welding gun, and watch the feed rollers.
If they are turning, then you need to increase the force on your rollers untill the wire starts feeding.

If the rollers do not turn, then you most likely have a bad switch, or connection in your welding gun or your speed control

Good Luck

Too much tension would smash your wire and it would not run correctly. Are you sure you are using the correct size rollers for the wire you are using. Rollers come in various sizes and applications. A knurled roller is used for flux cored wire. Make sure you sizes match up. They are stamped on side of rollers. Good luck!

When trying to weld,the feed wire gets red hot

There are loose connections and / or a short in the gun.
sounds like the gun is grounded, and the gun is welding the wire to itself.

I think you mean you have a Miller Synchrowave 200.

Typically, you would want to use AC below about 250 amps. In this case (to keep it simple), use AC, adjust your balance to about 4, use an 1/8" pure tungsten, pure argon at about 20CFh, and set the panel at 170amps to get things started. For general purpose, use 4043 filler.

Now - these are just generic settings, but they will get you going.

Bottom of canoe is cracked under the front seat almost all the way across can it be repaired

Is it made from plastic or fibeglass or alum?  For plastic or fiberglass I would try a very good epoxy. For alum. I would try to find some one to weld it. There are some very good epoxy's out now. 3m makes a panel adhevsive for auto use that will fix just about any plastic/fiberglass you may have.
