Question about Welding Tools

1 Answer

My Arc Welding machine has 3 outlets for 50A, 100A and 150A. I have set it to 50A. I tested with a tester. At the 50A outlet I am getting current. But there is no arc. The ground is connected properly

1.whether it is tranformer type or Rectifiert please find. 2.If Transformer check the oil level. 2.if rectifier Please check the outlet with the meger instrument to find amps generated while you trying to weld 3.Please check earthing cable is fixed directly to the metal where you are going to weld

I have a mishto 220 mig tig mma I can get the arc to work fine but the mig there's no arc at all the machine sounds like its welding but no arc at the gun I'm using gassless wire I thought it may be an...


They told me at welding school the mig transformer has a different slope (whatever that means?) to the tig and mma transformer so I am a little surprised at your question. The implication is two transformer are needed for the three types of welding and for tig and mig a dc converter and also for dc mma welding.

From your description it seems as though welding current is not arriving at the tip of the mig torch or the current is arriving in the wrong form.
You say the mma is fine but you didn't say whether it is fine on ac welding, dc welding or both. I have not tried mig welding with ac and have no idea whether it would be successful but I imagine a lot of sparks and not much welding. The problem could be the rectifier unit is either not working or is switched out of the circuit.

Polarity is important too with dc tig and mig welding.

I hope this provides food for thought.

Outlets do not work, circuit tester says Hot/ground reverse but all connections appear correct, circuit is on an arc arrest breaker.


Move wires to different breaker with same amp rating?
Try different tester?

Test wiring box-by-box to locate the reversed connection.

Check each box for Hot and neutral:

Testing household outlets with 3 light tester


Have you tried to determine if the problem outlets might be controlled by a wall-switch? This could be the case if separate black wires coming into the box are being used for the different outlets.

Outdoor Outlet Does Not Work


Your outdoor outlet(s) may already be ground faulted: often these outlets are fed from an existing GFCI outlet; check your bathroom(s) or kitchen for a GFCI receptacle. Use the tester he mentioned to see if it is live – be SURE to get a tester with the button on it that checks GFCI's as well – if the tester button kills the GFCI from any outlet on that circuit, you know the GFCI is working. Using the tester in your outdoor outlet verifies the GFCI AND the wiring to your outdoor outlet – something the GFCI's 'test' button can't do. ...Wilzard

Hi..

To diagnose your solution you need to check this steps that i can provide you
  1. Check that the washer is plugged in securely
  2. Check the circuit breaker of fuse box. "A circuit breaker provides protection for each of your electrical circuits by stopping the flow of current if an overload or fault occurs. When an electrical fault occurs or the load on your circuit becomes too great, the breaker on that circuit trips and interrupts the flow of current to that circuit. A tripped circuit breaker is still sometimes referred to as a "blown fuse" in reference to the older technology that circuit breakers replaced. If your home uses an actual fuse and not a circuit breaker."
  3. Test the outlet for current. You can test an outlet to determine if current can flow with a voltage tester. Always test your test equipment for proper operation before use. If you don't have a voltage tester, simply use a shop light or other convenient electrical device. Start by making sure the tester is working and plug it into a circuit you know is working. Note that if you need to test a 220V outlet, these instructions do not cover that test.

If there is no voltage, make certain that the outlet isn't controlled by a switch. Try all nearby switches and check whether the tester lights up.
If you are troubleshooting an outlet that isn't working, some possibilities include:
  • The fuse has blown or circuit breaker has tripped. Click on the following links for more information on replacing fuses and resetting circuit breaker.
  • The outlet may be in a circuit with a GFCI outlet (ground fault circuit interrupt). If the GFCI outlet has tripped, it may cause other outlets on the same circuit to lose current. Look for an outlet that has a "Test" and "Reset" button. They are often located near water such as in a bathroom or kitchen. If the outlet has been tripped, unplug anything that may have caused the fault and then press the "Reset" button.
  • A wire connection has become loose. A wiring fault can occur in many places, the most common include the outlet box, another outlet or junction box the wire passes through or at the circuit breaker.
  • Outlets can wear out, a replacement may be needed.
4. Check that the water supply valves are turned on
5. Inspect the filter screen.
6. Test for overheating
7. Test the water level switch
8. Test the timer control
9. Test the lid switch
10.Test the water inlet valve


Good luck !!!

  1. Inspect the water pump
  2. Test the centrifugal switch
  3. Test the motor

Miller bobcat 225g plus welding problem


If the idle is not working, then it is either you idle solenoid attached to the carberator or your idle board is bad. If you apply 12Vdc to the idle solenoid is should move, if not then the solenoid is shot, no good. If it works then you idle board is bad. Also, check to see if you are 60Hertz by measuring at the outlet with a frequency meter. I recommend a Fluke meter. You should have 120Vac and 60HZ at the outlet. If the frequency is low then your engine speed needs to be increased. The idle solenoid could be causing all these problems.

Speed will not kick up when arc is struck


There are CT;s (current transformers) that the transformer output runs through and the AC outlets which sense the current flow and throttle it up from the control board.
Also, Is the throttle linkage free , not jammed up??
