Hello, new to the forum, and just put my intro up a few days ago. The first area I need some help to clarify the correct operation of my K930-2 TIG module. Per my signature line, the power supply is an Invertec V350 Pro. Here is my question. I am using a CK17 torch with the thumb amptrol. When I set my max amps on the Invertec (120A in this instance as I intend to fab a bracket out of 1.8" 304 SS for motorcycle exhaust application), the moment I touch the amptrol, the Invertec starts to show and amperage decrease AND voltage with no arc established yet. Bear in mind, I have only used the module one other time, and do not recall any voltage showing on the Invertec until the arc was initiated. I recall being able to dial in a precise amperage via the thumb control (in this case I was attempting to dial to around 90A to start), but the voltage remaining at 0, until an arc is established. Has anyone experienced anything like this. I believe all connections to be correct. I have the Invertec set for negative polarity for DCEN TIG welding. The negative on the invertec is connected to the "electrode" tap on the TIG, and the positive to the "work". Open to any suggestions or direction. Thanks everyoneLincoln Invertec V350 ProLF 72 Wire FeederK930-2 TIG Module
Reply:Gee,It might be that the thumb dial has to be rotated to the very start of the dial first, where the on/off switch occurs.
Reply:OK. Thanks. On the Lincoln Hand Amptrol I'm using (north south track type), I can definitely feel a notch or detent at the very beginning of the of the travel which would be the on/off I'm assuming. So this is the scenario I am curious if it correct, or if I have something malfuctioning. Let's say I have the power unit set at 120A, the amptrol in "off position" and I begin to roll the Amptrol to "on" to increase amperage. I have the torch at a far distance from the work and there no arc is established. Would you expect to see any voltage yet on the power unit, or would you just simply expect the amperage number to change with no voltage? Thanks again for your helpLast edited by Chip4664; 05-23-2017 at 04:08 PM.Lincoln Invertec V350 ProLF 72 Wire FeederK930-2 TIG Module
Reply:Gee,It's possible that the amps/volts could show on the panel according to the potensiometer of the hand dial, even when an arc hasn't been established. I've never bothered to check on my unit about that, that I recall.I'd just establish the arc first. Is there a High Frequency toggle switch somewhere? If that isn't on, you may only be able to get an arc by scratch or a lift start.Otherwise, there's undoubtedly a few members here with that same setup who could better help you, but you might be able to get it with some trial-and-error on your own.Last edited by C.

Reply:This is becoming a bigger problem with electronic in welding machines.Back in the 1960's and 1970's the most welders where variable transformed they still working today. Today electronics gives great bells and wishlists. But look how many cell phones or TV you purchased since 2000. Good luck I hope something else.Dave
