It must be a open circuit voltage issue then, most likely as those same rods sputter out repeatedly on my home unit, behaving just like trying to burn lo-hi's on a buzzbox..
Though they are a cheap should I dare say 'just about does the task when run right' type of rod. They are with no doubt imported junk...
I sneaked in a dozen of my Esabs into the college today and burned those instead. I can't see that being classed as cheating, as the aim of the course is to produce consistant welds. You dont want cheapo rods hindering what progress you are making.

Tried that too but you knacker the first end, turn it round then knacker the second end and you can't get it out of the collet!
Not that I do that any more of course

Tig you push button to start a weld via hf. Then it just a matter of keeping the wire and travel speed smooth without contaminating the tungsten or getting carried away.
Yea it's fas basic

Ah, I see and the gas will automatically begin the flow once the button is pressed? , much like a MIG does?

Whats this business about different grades of tungstens?
thoriated? etc

Ya it's like a mig, you can hold the button and weld or use 4t and push the button to start and push it again to stop. White tip tungsten is for alu gold tip is for stainless, and red is thoriated got any thing really it a real good tungsten.

Can the instructor demonstrate the welds using those rods? If he can't they shouldn't be using them.

Done everything today, tommorow is destructive testing 
all the paperwork is out of the way, and I'll be going for a B.S. 4872 in MMA, in mild steel thickness ranging from 3mm - 12mm in flat PA position, PB flat/vertical. Possibly go for the vertical up, down and have all positions covered. Its only £300

You would be doing 'stoving' for vertical down, usually only on pipe butts with CEL electrodes. Not something they generally teach in college
I've used a heap of stoving rods in this place, its a professional welding association, but its kind of sounds nerdy, so I use the term 'college'
I've burned cel's, iron powders, basics, rutiles, pretty much every rod you can get for mild steel. I'm always hunting through their ovens for anything other than plane jane 6013's.
