Hi Otto, thanks for your reply. I have just had a look at my gas flow, currently running 15CPH (atleast thats what it says on the ball gauge thing) Post flow is set to about 3-4 seconds, although im impatient and sometimes just take the torch away as soon as I stop the arc. I welded scratch start fo...

Hi Everyone, I decided I need to make some actual progress with my welding learning, so I got a local metal shop to cut me 120 3x3inch squares of aluminium, 3mm thick. This is so I can just weld them to each other, or weld them into cubes and can practice various types of joints etc etc. So a few qu...

Hi Everyone, As a spinoff from my other thread (about keeping the electrode clean, which I have now mastered, thanks for your input) I am now wondering about something else. I have noticed that now I am using 8 seconds of postflow to keep the electrode shiny, the very ends of the weld are coming up ...

Well I started with a cheap scratch start tig machine and the only way to stop the arc was to just take the torch away from the metal (or snap out) and so the elecrode was gray and tatty within one weld, and the scratch start process was really hard on the electrode tip so you very rarely got the el...

Thanks for the suggestion, I will twist the post flow knob and see what happens. My flow is at about 5ltr/min (i think this is about 10.5 CFH)

Should I turn this up too?

Pete.

Hi Everyone, Just been watching Jodys video here about lap welding, and if you skip to around the 4.50 mark, you can see him do a pretty bad weld (for demo purposes) and then show the electrode. The electrode is shiny, clean and seems to look as though its been freshly ground. https://www.youtube.co...

Hi Everyone, I did some more playing and I think ive got the hang of it. https://fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-xpa1/v/t1.0-9/10178106_10152631983517570_3315382264176176214_n.jpg?oh=0741d9c22a7e98692bb1b505a21697f1&oe=549655B9&__gda__=1419501999_c8360464123bc26c285ad684f8096ee6 A ...

Hi Everyone, I have been tigging steel for a while now, and when I bought my current machine, I bought AC so I could one day start to do ally. Well I decided to give it a go, and I think I am on the right track but there is one thing I cant quite work out. I am using a 1.6mm white tip tungsten, with...

What do you think? 3mm mild steel....

Hi Everyone, So annoyingly my inverter does not have lift start. Il have to practace normal scratch starting then. My Tig finger came today, but its not big enough to get over my gloves. I do have pretty heavy thick gloves, I would like to upgrade myself to some of those nice thin tig gloves at some...

Hi Everyone, I had seen the buzz box video, and I had seen the flicking the rod between the work and the tip. I havnt tried this yet, as im not too good at holding the torch really steady yet, il get there. You say lift start, and most basic inverters have it... What is it? My inverter is basic, but...

Hi Brian, Thanks a lot for your info, its nice to find a forum with good helpful people on it. I mistyped my sentence about negative earth, I am in fact using positive earth, I just typed it wrong. Just out of interest, if I had it the wrong way round (negative earth) what would happen? I have alrea...

Hi All, Im new to tig welding (this is my fourth day). I have a 130amp scratch start inverter, with a pretty standard torch (I am set up as negative earth, as im told is correct). Im using mild steel mig wire for filler at the moment. Im using 1.6mm red tip tungstens, sharpened the correct way on a ...
