NEwbie Help, is this too thick for my TIG ?

[Calico]

I just learn/start welding using this TIG, my TIG dosn;t have High Frequency.

the result is ... the tungsten was "eaten" fast, every touch I start it just eat the tungsten wire.

I know my skill is zero, but I think something wrong with my TIG, I think it's too small to weld the 6mm thick.
is it ?

see the attachment pleae

and help
I got this huge project waiting.
all info is in the photo, sorry my cellular photo quality just like my welding skill.

Ahhh, where to start.
By the sound of it you may have the leads hooked up wrong. The power lead to the tig torch should come from the negative -- side of the welder
Also maybe oxygen contamination in your argon flow. Push the tungsten in all the way and seal the end of the cup with your finger, The ball in the flow meter should fall to 0. If it doesn't you have a leak somewhere. And I would agree that that welder is on the small side for your skill level and the looks of your project. I would suggest a smaller project to learn on.

You will need to set it up using (AC )with High Frequency for alum.

(-DC) NO HF For steel

wow wait a second,
my torch is connected to Positif and the negative connected to the material I weld.

correct ? thisis what the seller said to me.

[powerr]

you connect the torch to negative and the work to the positive check out miller welds. if you look in the tech section you can download their tig hand book. i am just learning my self so i know where you are at

[Calico]

ok I got it HF for alum.
steel no need HF.

thanks

what about the polarity, did I connect it wrong ?

First off the material shown is steel, not alum. So there is no need for AC.
Second, for steel tig, the leads have to be DC- for the tig torch. DC+ for the ground.
Third you dont have HF but if you did you would use it for steel and stainless, but just to start the arc, that way you dont contaminate the tungsten.

my god, I'm so wrong about polarity.
how much argon flow aprroximately if I weld steel ?

ok my newbie question,
if I use welding for steel without argon, just a stick attach to the torch, do I need AC or DC ?
if it's DC the torch is connected to positif right ?
