Ok, who can tig weld? Or are willing to give out a bit of free info.

What is Crater?
Also Crater current?
Cleaning -4sec to +4sec??

What does the Pulse Current do?
I have pulse frequency of 0-350hz but also Pulse Range of 10%-90%, what does the Pulse Range do?

 

Anybody?

Take a guess then?

I can give you the profesional level practical and theoretical lessons about TIG welding, but my English not so wery good and I live in Europe.

My advice for the begining, try to be somehow near proffesional with protection mask and watch how he do that, how he moving with hands, how he actually working. Reed some theory about materials... Then try do in itself. Nothing difficult from my opinion.

 

Thanks for replying guys ...

 

I just started tig welding.

Cleaning - Do you mean purge time? ours is 4-6 sec. It gets the gas forming around the puddle first before you start so you dont have problems. Or do you mean i think its DCRP, which has a 'built in' cleaning feature with that current. Think its DCRP have to check my notes.

Pulse range? HighFrequency maybe? Used to start the arc on aluminum and i think... titanium.

As i said im a noob with tig.

 

I think DCRP, it dials from -4 seconds to +4 seconds...
The pulse is the function of the machine, DC and AC, but I read on the miller manuals how exactly the pulse range/current works

Crater filling is for when you finish it doesn't leave a hole, so I guys I'll just have to play with these buttons to figure them out.

 

Crater and crater current are the settings which your machine will go down to at the end of your welding, usually a much lower setting than your welding current so that when finished, your weld pool is flush rather than a crater which can promote crater cracking (where a crack propagates from the crater)

Cleaning -4sec to +4sec??
I'm not sure on your machine but on mine cleaning action is a function of AC balance where on AC (aluminium welding) you have the ability to "tighten" the arc (less cleaning) good for fillet welding. Or increase the cleaning action which gives a softer broader arc more suitable for butt or external corner welding.

"What does the Pulse Current do?"
Pulse current allows you to set a base current say of 100 amps and then you introduce a pulse current say 170 amps. Your weld arc then oscillates between the 2 settings allowing the weld to cool down in between pulses. Great for thin materials and outside corner welding, the pulse side of the current tells you when to add filler wire giving that professional 1/2 dime look we all strive for.

"I have pulse frequency of 0-350hz but also Pulse Range of 10%-90%, what does the Pulse Range do?"
The pulse frequency is the number of times in a second the pulse switches from cold to hot. I like a pulse frequency of around 0.7 to 1.2 it's a bit slower but allows for very precise introduction of filler wire.
At a guess, I would say that pulse range for your machine would be the length of time your pulse compares to your base current. eg. if you have a pulse range of 90% then your base setting has a 10% length of time to a 90% pulse time in 1 second. Alternatively if your pulse time is 10% the base current is now 90% in 1 second. I like an even ratio between base current and pulse current of 50% so that in 1 second 50% of the arc is cool and 50% of the arc is hot.
I hope this helps. Regards Andrew.

 

Thank you Andrew excellent explanations!!!!

I will get the gas and helmet this week and will play around with the machine.
