i need your serial number to get correct info...please reply here Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Your remote might be going bad. What type of remote, what type of machine with serial number?

Your polarity needs to be switched for Tig operation. In other words, the electrode will be negative. Make sure you use the proper gas for Tig, usually Argon.

Your problem is in one of two areas. The controller board inside the unit or a bad trigger on your gun. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Check your foot controls first the POT my be acting up change it out w/another if you have one,

Some welders have a resistor that is obvious and accessible but to give an error code it is likely something else inside. You'll have to look at the circuit board for a component that is burned. If you are lucky you will find a fuse.

DC current, electrode negative (DC Straight, DC-), High frequency for start only (really don't have to use high freq at all for steel but it helps establish the arc without scratching), 1 amp per thousandth of material thickness is a good setting to start, adjust from there for the job. 1 amp/thousandth also applies to aluminum- it has a lower melting point than steel but conducts heat much better so power to weld is very nearly the same.

Use a sharp tungsten, don't ball it at all (as you would for AC work).

It's likely that your pedal is the problem. Pull the cover and check it electrically - these have been problematic in the past. You can further troubleshoot by selecting constant output and test the output.

Hi:You will need a 125A breaker if using 220V/1ph.

1. Make sure a qualified electrician specifically selected and installed your wiring and breaker for this unit.2. Carefully examine all of your power supply connections, wiring, grounding connections (clamps, lugs, and nuts) and cable. 3. Be sure you don't have a steel washer between the grounding lug and the machine power base. 4. You must have a minimum of 4 gauge wiring on your power supply and 2 gauge grounding cable. 5.Take a 3/8" socket and open up the machine and thoroughly examine with a bright flashlight for any electrical burns. 6. If the machine is too dirty to see the components, then disconnect it from the electrical service, lock-out / tag-out the electrical breaker, take the machine outside and wash it down with a hose -- preferably a light duty pressure sprayer and some Simple Green. 7. Let it air dry for 24 hours. Then re-examine.

Use a heat gun to warm suspected parts and isolate the problem. Look for electronic components. Also verify that your torch hose doesn't have a problem. At cold weather they get stiff and may have a problem with wiring. The torch cable is MUCH less likely than a part on the control board. It will take several days to isolate as you will have to wait a day for the unit to cool back to the failed condition. If you can isolate to a smal portion, try using circuit cooler to chill suspected parts back into failed mode.
