Help! 210 EXT Setup for aluminum

[everlastsupport]

Im welding with 6061 t6 Aluminum .090 and some how my machine was reset and I lost my settings. since that happen I can't seem to get my welder to perform as good as it was. Can anyone give me there settings so I can readjust my machine? Below are my settings

2% lanthinated
100 amps
25 argon
1 pre flow
7 post flow
30 pulse amps
1 hot time
50% arc force
50 frequency
-15 cleaning balance
advanced square
0 up slope
0 down slope

25 Agron? Should be 100%. Arc force not needed. Sure you do not have the MIG tank on the TIG machine?

If 25 is gas pressure, lower that. Also can you post pictures of he weld?

Also frequency is way low. Need about 100-120. Hot start doesn't have anything to do with it either.

its 100% argon 25 cfh. Ill post a picture after I go back out to the shop and get back to trying to figure out these settings. but I believe that my machine only goes up 100 on the frequency

In the future, when you get the machine all dialed in for a task you do frequently, you might want to make a habit of saving those settings to one of the memory slots.
That is one of the main advantages to the digital machines. Of course with the analog machines, you can always just snap a single photo of all the knob settings, where on the digitals, you would have to step through and write them down or record them. You are a little unclear in the wording of your settings, and are missing some. Is the frequency, the AC frequency or the pulse frequency? I suspect the later. That material is thick enough that you can probably shut off the pulser, at least to begin with. That will give you less to adjust and make it much easier to see the effects of your adjustments. Are you using the pedal or torch switch?

The manual should tell you which settings are for TIG and which for stick, but here are the basics for TIG:

Start amps, End amps, Upslope, Downslope, Preflow, Postflow, AC frequency, AC balance, 2T/4T, Pedal/Torch, Argon cfh, with pulse add these, Pulse amps, Background amps, Pulse frequency, Pulse on time (duty cycle). Some of these might be named a little different depending on the machine.

Yes, it could be a max of 100 depending upon the model. But it needs to be set at max then.

ok I think I got it back up running well. Changes in my settings I'm also using 3/32 5356 filler

im also pulsing 2T

2% lanthinated
100 amps
15cfh 100% argon
1 sec pre flow
7 sec post flow
5 pulse amps
1 hot time
65% arc force
100 frequency
+5 cleaning balance
advanced square
0 up slope
0 down slope
100 Start amps

all the weld runs that are in the picture are from me adjusting all the settings. I found a happy medium. to get a brighter weld I was trying to use more cleaning action but maybe its the filler I'm using. I was going to try 4043 next

Arc force and hot start time have no effect in the TIG mode. Those settings are for stick only. You can back off the cleaning, quite a bit. That is what leaves the frosty band around your welds. The trick is to set it to just clean the area where the weld is, and not go out much farther. It doesn't look like you are using a pedal, so adding some downslope time will help you to eliminate the crater at the end of your welds. Those craters are where cracks start. One thing you should do is to clean your aluminum before welding. That will make your welds a lot more shiny. Give it a once over with a stainless wire brush and a quick wipe with acetone. While the cleaning action of the welder can break up oxides to let the aluminum flow to the top, it doesn't actually remove impurities. Those will all float to the surface of the puddle and leave residue. Good TIG welding is all about prep.

Welding tips and tricks has a whole series on what all the different TIG settings do. You might want to go check that out.

You don't need 100 start amps. In fact your tungsten would last longer and stay sharper if you ease it down to 20-30.
