SOURCE: Mig welder

Sometimes dirt builds up at the beginning of the liner, at the drive. Eventually the dirt jams in there so much that it gets very hard to push the wire through it. Carefully cut the wire between the spool and the drive and secure it to the spool through a hole, so it doesn't unspool into a bird nest, then disengage the drive roller, the wire should pull out of the tip freely. If you feel resistance when you pull it out, either there is dirt at the beginning of the liner, or the contact tip is causing resistance. Without the wire in the drive, turn on the machine and try it watching the drive. Does the drive work freely now? Does it change speed with the rheostat? If its a problem with dirt, this is what I do, after you get the wire threaded back through the drive, liner and contact tip, and everything is working, take a small clean cotton rag and simply tie it around the migwire between the spool and the drive, in a way that the drive can't **** it in. This will constantly clean any dust/dirt off the wire before it goes through your expensive drive and liner. Whenever you change the spool, change the rag. Hope this helps, and please post your results.

SOURCE: NO WIRE FEED BUT WELDER CLICKING AS IF FEEDING

This could be caused by not enough pressure on the drive wheel. Try adjusting pressure as spelled out in you manual.

SOURCE: my welders wire speed control will not slow down

Speed control potentiometer is good place to look.
Put meter leads on it, set to ohms position and see if there is a variation in ohm values when rotating knob. If not it is bad. Take it out and spray it with panther ****, sorry, cleaning lubricate and see if that will fix it before buying new one.

Hobart beta mig 170 wire feed wont adjust


The variable speed motor runs on 0-24VAC controlled by the speed control dial. The dial may be toast. Replace this part first. You may verify the part failure by using a bypass wire to see if the motor runs at maximum speed without the control dial (rheostat or potentiometer).

Turntable running slow


Most of the 'direct drive' turntables have a "pitch control" dial - you turn this dial until the black bars 'stop dancing' and hold still. There should be a little window with an orange neon light where you can see these black lines and adjust the speed. You may have to adjust it everytime you switch from 45's to 33's.

Thomas Pacconi Model TPC-MSE-800 turntable runs slugglish. 78 runs fine but 45 or 33 runs slow. I removed belt cleaned it and platter. I put a drop on oil still same problem. Do I need a new belt? This is...


Pjam,
Had the same problem & checked around on the net. Several people tried replacing the belt, but it had no effect. Spoke w/ several repair shops around the country and they concur with what I'd read on the net - bad motors. 3 or 4 repair/supply shops told me getting a motor would be impossible. Since I only listen to 33-1/3 LP's, I messed around w/ it a little and found a solution. Take the turntable out of the unit & you will find a small circuit board attached to the bottom. On that board is a small square blue fixture w/ a white circular "dial" in the middle (has grooves to accept a small straight blade or a phillips screw driver). This controls the voltage to the motor, which in turn controls the motor RPM's. If you set the selector switch to 78, you can experiment /w turning that white circular "dial" to slow the motor down. It isn't very hard to get the speed set properly. The down side is that you will only be able to play 33-1/3 LP's, but they are probably the most common anyways. I assume you could do the same to set the speed for a 45, rather than a 33-1/3. Down side is that you will only be able to play 1 size LP on the 78 speed setting, but it's an easy adjustment that can keep an otherwise in-op turntable functioning. Good luck!

Just installed the new t-104 and the clock runs slow


The clocks on Intermatic timer run on-time for years.
If this a new timer >> then buy another one, and swap out the insides without changing the box, and return the bad one.

Voltage variation will not affect clock speed. The only electrical thing that affects speed would be the cycles. Your household has 60 cycles. The clock motor is 60 cycles.

When you connected wires, the wires fit under a metal clamp and the screw pushes the metal clamp down against the wire > only copper wire should be under that clamp > if some insulation is also under the clamp, then the contact might not be 100% all the time, which would stop the clock. Check that all your wire are down tight.

If wires stop in a junction box before arriving from breaker box, there might be a loose connection in that box. Trace back your line, especially if this is a pool control with a junction box.

A shorting breaker can stop voltage from time to time, making it appear as if the clock is slow. If one leg of the 240V stops, the circuit stops. You can check breaker for loose screws. Does breaker feel warm? Is there a crackling sound when you jiggle breaker. You can put your timer 240 lines on similar sized 240 breaker and see if clock runs slow ... that would indicate whether the problem is clock or breaker.

If timer is old, the plastic clock gears can get worn. The metal timer gears rust or clogged with dirt. Snap out the insides and inspect for rust and dirt. Use a little WD-40. Turn off power since WD is extremely flammable.

Snap the manual override back and forth. Does it snap crisp? Or is it sluggish? The clock motor turns the dial until the tripper encounters a metal lever. The Clock keeps pushing the tripper until the tripper clicks the metal lever >>> which happens to be the same lever the manual override is connected to.

So if the manual override is very hard to push ... ... a sluggish manual override might slow the clock. You might put some grease on the lever where the trippers touch.

Finally, the clock motor can go bad.

Error message E21


E21 means the treadmill is not picking up a speed signal once the start key is pressed. First, determine if the motor is turning before you get the E21 or not. If the motor turns, the speed sensor is the most likely problem. If it does not, you can manually turn the belt with your feet before you get the E21 and you should get a speed reading but eventually you will get an error code because it is almost impossible to keep the speed constant enough for the computer. Try running it through calibration with the motor shroud off.
Press the Stop and the Speed Up keys down while inserting the safety key.
Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test.
Press either incline key and the incline will calibrate automatically.
On this next step do not step on the treadmill when you press the Speed Up key and hold it down until 85 is shown in the Distance window (some models may show the 85 number in another window).
If the top speed of the treadmill does not match the displayed speed on the computer console, adjust the max speed potentiometer (pot) on the motor control board. This is the board that the red and black motor wires connect directly into in the motor area. The Max Speed pot is clearly labeled.
The max speed potentiometer is a small black square with a white center and is located near the three small speed wire connections labeled H, W, & L. Using a small insulated screwdriver adjust this potentiometer clockwise to speed up and counter-clockwise to slow down the max speed of the treadmill. A tiny turn of this potentiometer will make a big difference in speed so be careful when making adjustments.
It is not important to get the speed set exactly at the max speed of the treadmill but do make sure to get the speed within .2 MPH of the max speed of the treadmill. For instance if the max speed of the treadmill is 10 MPH, make sure to have the speed set between 9.8 MPH and 10.2 MPH. Some models have a 12 MPH top speed, so please check your manual if you aren’t sure.
After completing calibration of the speed, press the Speed Down key. The treadmill will automatically return to 0 MPH. Please allow the unit to stop completely before continuing, press the Stop key once and remove the safety key.
If the motor does not run, test the motor but first unplug unit then unplug the two leads ( Red and Black ) that is connected to the Motor Control Board.Cordless drill battery- get a fully-charged, 18 volt (preferred) cordless drill battery and on most treadmills connect the red and black motor leads to the battery (some have different colors but if you have two wires and get it hooked up backwards, the motor will just run backwards and won’t be harmed). If good, the motor should operate at about 1 MPH. Then Motor Control Motor will need to replaced

Wire Speed Increases when voltage increases


What is it doing? stabbing the wire into the work? The voltage is too low for the speed of the wire feed.. Turn up your voltage and slow down the wire. then increase your wire according to the speed of travel of weld. That is an awesome machine but it is still up to you to get the settings dialed in. Good Luck, Ned.

Sound wavers (speeds up and slows down)


you need to replace the Pitch controls. I'm presuming it is a sliding pitch control. Use the Red start stop lights that reflect on the rotating wheel. put the pitch in center 0. does one row of the dots on the wheel stay completely still.now just turn it up op down a bit until it starts to move the dots slightly. now watch the dots now while there moving. Do they fluctuate they should be smoothe. do this on both decks to find out which one is fluctuating.
