First time tig setup help needed

admin

So I went and bought a ck worldwide 150amp air cooled torch. I bought the starter kit with tungsten cups and collets. And a cover or the hose as I heard the superflew hose is very fragile and I work in dirt that's littered with junk. My question is for 3/8 plate how should I setup the torch? It'll be a scratch start setup and it has a gas valve. I only have argon co2 mix right now. Can I get away with that till the bottle is empty and I can exchange it for straight argon? An eventually I'll be using this for root and hot pass on pipe I practice on. Any input is appreciated. Sent from my iPhone using Tapatalk
Reply:Sorry...Your gas is totally INCORECT!Do not even try it.You will just get angry and give up.STRAIGHT ARGON is what you need for ANY steel....So put the torch away until you have the proper gas....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Short quick answer, you'll need to have straight Argon in order for this set-up to work. Otherwise, the mixed gas will allow your tungsten to burn-up. You'll also need to be sure that you connect the torch to the neg.(-) side of your welder and have the ground hooked up to the pos.(+) side, straight polarity. As to initial amperage settings: anywhere from 65 to 70 amps on the low end and up to probably around 125amps on the high end. Providing that you are practicing for pipe roots on heavier schedule pipe. If you are going to be working on sch. 10 materials then you may need to be slightly lower with the amps. Good luck and best regards, Allanaevald
Reply:Thanks for the quick responses. Is there any specific pressure I should shoot for when I get straight argon? I'm assuming I'll need to sharpen the tungsten to a point? How about cup size and stick out on the tungsten? And anything else that's important? I'm not familiar with tig welding in the least bit Sent from my iPhone using Tapatalk

Reply:agreed about being able to watch a youtube video and have a lot of info presented to you for you to actually see. Start with a number 7 cup. Its not supposed to stick out any more than the diameter of the cup. Gas, 15-25 cfg. Yes tungsten to a point. Best bet is do some watching and report back with anymore questions you might have or if something is unclear.- Christian M.C3 Welding & Fabrication - CNC Plasma Cutting-Mobile Welding-Custom welding and fabwww.c3welding.com

Reply:Originally Posted by MikeGyverpressure is completely irrelevant, you need about 10-20cfh (that's a flow rate)
Reply:Some gauges will have a pressure gauge instead of an actual flow meter, but they also have a certain orifice size internally, and a given pressure through an orifice will result in a certain rate of flow.Welding/Fab Pics: www.UtahWeld.com
Reply:You may find my posts in this thread to help learning. It's just one of many I've done covering the same material. In you case with no pedal, you'll have to make a few minor changes to my instructions. When running scratch start, you control the "heat" with arc length, travel speed and by adding filler to chill the puddle. I'd set the machine on the lower end of suggested settings as it's easier to slow down or increase torch height to ADD heat, than it is to try and speed up or chill the puddle with filler on average. For 1/8" material 100-115 amps vs 125amps or higher with a pedal.Play with changing arc length so you understand what happens and why for a bit, but when learning, keep things simple and try and keep torch height as a constant for now. Just use travel speed to control the heat. Once you get to the point where you do this automatically and are making consistently good beads, THEN you can work on adding torch height into the mix at the same time.http://weldingweb.com/vbb/showthread.php...ng-to-tig-weld.No government ever voluntarily reduces itself in size.

Reply:Thanks for the info guys I have hard time finding this stuff on my phone when I search. I have to get fuel for my machine and some wire and I'll be practicing soon.  Also I'm not sure which size orifice is in my regulator but I have a regulator I used for my mig for argon co2 mix can I use that reg? And or hose can I build one with ferrules fittings and hose clamps or does it have to have crimped ends?Sent from my iPhone using TapatalkLast edited by strtspdlx; 11-05-2014 at 11:25 AM.Reason: add text
Reply:I know it isn't pretty but I'm trying. Porosity is a combination of my stupidity for setting up right next to my machine and the cooling air from the engine blowing gas away. A windy day and the fav that my building bit exactly "leak proof" and impatience. Got that all sorted and these are my results. Definitely need more practice. Sent from my iPhone using Tapatalk
