20 LPM is really high - that's about 43 CFHScottyfish wrote:ok thanks once again guys, ive gone backwards tonight...came home resharpened some tungsten, upped the gas to 20lpm i also changed the gas nozzle to a size 8.
After doing that i got a very stable but weak ark that seemed to just burn an oxide layer...no white smoke, no tip burn..but yeah no puddle. Tried re earthing the job itself but yeah...no go..
So i thought to myself maybe the HF points are dirty as the welders been on my garage floor for well over a year with no use..
i got a little 2400 grit and gave them a quick wipe over then a wipe down with acetone. put her all back together and now i have nothing..i get gas flow when i hit the foot pedal but no ark not even an attempt...if i touch the base material i get it stuck and a small spark...
I took the machine all apart and checked it over again but yeah i cant see any issue...i wonder if the HF gap is now to big? Its one that cant be adjusted like some of the ones ive seen on the net.. solid mount into the circut board with 2 prongs coming out with copper points.
Might be time to get it looked at..

Agreed. 20 CFH is reasonable. That equates roughly to 7 lpm.

Ok, spoke to the seller, ill send it back for him to check as I have had poor arcing from the get go. I did try on 5lpm,10,15 and 20 all with the same issue. maybe there is an issue with the HF circuit or the AC circuit.
I will check the gap of the points tonight as if that fixes the issue id be stoked
If not Ill ship it back up next week and see how it turns out.

Yes, looking back at the original photos, I presume that the machine doesn't self-start the arc when you hold the tungsten near (1/8") the job and pull the trigger. Does it do that, or are you initially touching the tungsten on the job to try to start the arc?

I'm interested to know if there was any update with the machine? Did it get sent back? Did you get any success yet?
Thanks
