Its probably the torch. Turn off the hf , with the machine triggered Measure the open circuit voltage from the positive o/p socket to the negative with a multimeter set on d.c . The correct no load output voltage for the machine will be shown on the spec plate as Uo = ........and whatever the voltage is. If you get the correct voltage try another torch or try stick welding.

What settings do i use to arc weld.


Not sure what machine you have, but it should be DC straight (electrode negative or DCEN) and DC reverse (electrode positive or DCEP). The polarities have different characteristics. For example, if you're planning to TIG weld, you would either use DCEN or AC (if welding aluminum). For the general stick welding process, DCEP tends to give you a deeper weld. The welding rod you buy will have recommended machine polarity and amperage range settings, you should use the recommended polarity for whichever rod you're using because different rods are designed to weld under different circumstances. But, generally speaking, most welding rods for steel will work on DCEP without much trouble.

How too set up a tig welder for welding thin steel?


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).

The tig welder will arc but there is no amperage and nothing is heated up it acts l;ike there is no amperage?


Make sure you have a good ground. With high frequency you can get it to still arc but have a bad ground.

Bad tig weld job


Wow you have a lot of variables here. Let's go over some of them.1.AC current 2.100%argon shield gas 3.Check your Tungsten, it must be the recommended 1or 2% and the right size, clean and the tip rounded by meting 4. High freq. turned to continous-not just "START"
5. CLEAN,CLEAN,CLEAN your Alum. with a S.S. brush that has touched NOTHING else in in it's life!
Start here and GOOD luck
