Aluminoob freshman at Collier University

Postby mopeep » Sun May 14, 2017 7:32 am

I'm fairly new to tig and have been getting semi-passable mild steel results for my furniture and art projects, but am flummoxed by something on aluminum.
My foot pedal controls amps nicely in DC setting when welding steel, but when I switch to AC with no pulse the pedal acts like an on/off switch. its either wide open or snaps off leaving a cracked crater. Chance of this being operator error is probably 100%.
i Have RTFM.
1/8 inch 6061
AHP 200
AC
2T
no pulse
Balance 25%
Main amps 150
start amp 0 end amp 0 (same results with start amps 50, end amps 50)
3/32 2% lanthanated tungsten
3/32 4043
I can't figure out what I am missing. Comments?

Does your power source have adjustable up slope and down slope?
If so set to about 5 seconds each.

I know zero about that machine but I see 2t in your settings. 2t is an on/off setting unless you set an upslope and downslope value . Check that first.

Can you post a pic of the machine's front panel?

Good, we can work with that. :lol:

Like the other guys are saying, could be a sloped function. I believe most machines save settings from last time, say you used Lift TIG feature last on AC it will be there again when you go to weld AC so if someone welded with a certain setting, its very likely you have to change it around to accommodate you.

Not a lot of people use my welder but I am used to just always double checking the displays and buttons to make sure everything is set where I like it.

Its easier to figure this welding stuff out by trial and error than to upload a photo.

will keep figuring out photo and get back to you

Like this one? I've seen another configuration, but the important switch is on both. Put it in 4t mode, and your pedal should control your amps. If not, I'll have to review the manual to see if we're missing something.

If anyone can help you figure out what your problem is, its these guys here.

Pictures are very helpful, realize you might think you have a certain thing going on or seeing a certain thing or even think you have a certain machine, post a picture and these guys can tell you if your right or not.

Easier to solve these things by providing what they ask for, just like the cops..... well, kind of.
