First tig ever

admin

Never tried before it was 1/16 filler. 1/16 tungsten 30 amps and about 15 cfm there was alot of what looked to be burn that scraped right off. Attached Images
Reply:Your shielding looks insufficient, crank the amps up too. Good luck!Thermal arc 211iCk flex-loc 150 & 130Clamps, saws & grindersHarbor freight 80 amp inverter

Reply:It's really a trial and error thing. Watching Jody's videos on weldingtipsandtricks.com really helped me get started. First get the settings dialed in, super clean metal on both sides and sharp clean tungsten. Then it's all about arc length, torch angle and speed. It's hard when something is frustrating and addicting at the same time.Thermal arc 211iCk flex-loc 150 & 130Clamps, saws & grindersHarbor freight 80 amp inverter
Reply:Playing again tonight higher amps and gas getting this. Gas was around 20cfm Attached Images
Reply:The heat looks better, but I think you still have a shielding problem, way to much porosity. Are you reading the flow meter properly? 15-20 cfh should get you close with a standard collet, a little less with a gas lens. Give us a run down of everything, settings, cup size, indoor/outdoor, power source etc etc...Thermal arc 211iCk flex-loc 150 & 130Clamps, saws & grindersHarbor freight 80 amp inverter
Reply:Rod and filler are 1/16 amps i played between 40 and 60 today.  Cfm i think was 20 if i was reading it right might have been higher
Reply:Cup size was 5

Reply:High or low?
Reply:It's low, or you have a leak "upstream" somewhere. The shielding gas around the tungsten and weld should be 100% argon, somewhere & somehow it's getting contaminated with atmosphere. Having the flow set too high can cause problems at the weld, from turbulence "swirling" atmosphere into the gas flow. But argon flow set too high wouldn't result in the tungsten looking like that.Give me fuel, give me fire, give me that which I desire.
Reply:Turned it up another 5 cfm to 30 top weld was the result Attached Images
Reply:That bead looks better, but the orange haze around the weld & especially the oxidation at the end indicate something still isn't right. 30 cfh is WAY higher than you should need to be. Either your flowmeter isn't reading  properly, you have a blockage somewhere in the system resulting in less flow than the flowmeter indicates, or you have a gas leak somewhere. That's my bet anywayGive me fuel, give me fire, give me that which I desire.
Reply:Get a flow gauge for the torch end, so you can verify flow at the torch end.
Reply:Regarding the end of a bead how do i stop the arc yet keep post weld flow going.  Do i just pull the torch away kill the arc then go back in with gas?

Reply:Correct no foot pedal.
Reply:Just snap your wrist up to break the arc on this machine.  Check the back cap on the torch.  Make sure the oring is seating correctly.   You may also have the collet body screwed in too much or too little.  The collet body and back cap share the same threads.  So there is a little room where you can screw either too far in and leave the other too far out.  If the collet is screwed all the way in then the back cap won't go far enough to seat the oring. You can also screw it in too far so that the collet body partially covers the gas opening in the torch head.  Depending on which regulator you  have you may have either LPM or CFM on that unit.  Which regulator did you get?  And how do you have it connected to the torch since it's a gas valve torch? There may be some leakage at the connections. Soapy water will help you out there.The last thing I can think of besides contaminated gas is that you have too much angle in the torch.  Hold it upright or lean it no more than 10-15 degrees off vertical with the cup pointing to the direction of the weld.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT
Reply:Lugweld i know for a fact the back end is out so i think u hit it on the head adjustments tonight
Reply:Shorter weld is after fixing tig gun.  Back end is now screwed all the way in Attached Images
Reply:You still are welding over mill scale.  You need to grind it more fully to get rid of that contamination.  If it isn't full of grind marks and bright shiny, it isn't cleaned enough.  I don't mean just polish the mill scale, but really get in there and get that stuff off.  It'll cause more issues than you can imagine.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT
