ok but the dial on the pedal doesn't do anything either.

I know this is very late but just in case anyone else misunderstands the pedal and its knob. It actually does work but you have to unplug the pedal, change the setting, plug the pedal back in, what ever setting is done at the time of plugging in or the machine energizing with the pedal plugged in is what you get, it is not variable while plugged in.

Basic set up for AL TIG weld on a 200pi;
All settings are done WITH POWER OFF................This is incorect! You need the power off when changing TIG, PLASMA, STICK switch and the AC/DC switch.
Set Machine to AC
No foot switch
Set amps for; tungsten size & metal thickness
Set Frequency at about 70% of dial (the frequency is used to clean the AL while welding)
Set AC balance at 50% of the dial
Pulse OFF

After a successfully and good looking weld install the foot switch.
Set the amps dial on the welder to ZERO
Do not change the frequency or the ac balance from previous setup
Set the front dial on the foot switch for the tungsten size & metal thickness + 25%
Remember that the full clock wise on the front dial will give the max amps of your welder. Half way on the dial is about 50% of the welders max amps.
Pulse OFF
Varying the foot switch and the filler rod will give the stacked dimes appearance.

After a successful good looking weld power down the machine and Finally turn on the PULSE switch.
Do not change the frequency or the ac balance from previous setup
The pulse is used to give the stacked dimes appearance with out varying the foot switch and filler rod.
I like it for thinner metal, It allows some cooling to accrue.
Set Pulse Cur to 40% of dial
Set Pulse Freq to 80% of dial
Set Pulse width to 25% of dial
Set down slope to 10%of dial
With these settings were used to weld some 1/8 AL you should see and hear the Pulse operate.
Varying the settings will give different effects on the weld.
The settings are a starting point and NOT SET IN STONE.
HAPPY WELDING!!

Great tips. I was under the impression any knobs can be adjusted under power with no negative effects on the machine or the weld (not that an incorrect setting wouldnt effect the welds quality). Just that the knob on the pedal is not active once initialized. Also I believe it totally bypasses the knob on the panel negating the need for any adjustment on the machines knob. That is what I understood after talking to Simon pretty extensively on the subject. Of course I have misunderstood many things in the past and I am sure that wonderful feature will stay with me til the end. LOL

I have not made a correct statement when I said "All settings are done WITH POWER OFF" The onle excuse that I have is that it was about 3 am when I wrote it. I am sorry about that! The only setting that has to have the power off it the selector switch for TIG, PLASMA, STICK and the AC/DC switch. All other knobs and switches can be adjusted with good results and no machine damage... I will edit my post

Keith, I hope nobody in any way thinks I am not happy with my purchase or the attention I have gotten here. Everyone has been very receptive and helpful, the products have been well built and operate well. All things have some weakness, these are very minor in the scheme of things. Again Thanks

Keith:
Is this power cycling new? I guess I either haven't read the manual closely enough, or it isn't noted. It's certainly good to know.

This is my experience with my 200pi, granted it is a two year old machine!!!!! I am sure that they have improved them.

This should be in the manual, its what everyone needs to get started.
I printed this out and cranked up the 200PI, worked my way down the list and everythiing started to work properly, so I tried the pedal.
At first the pedal was going full power as soon as it clicked on but settled down and became variable.
I sprayed some elec cleaner in the pedal plug, it seemed to be working as designed.

Then I moved over to pulse and pulse worked good too with the settings listed. I lowered FREQ to slow the pulse down, works good.

Went back to pedal, pulse off and it went back to its naughty ways, 222amps on first click no matter where the dial on the pedal is set.
Powered the machine down and reset all dials, pedal dial too, powered back up and it seems to be working ok but arc looking strange and drifting around.
Then I realised I'm outta freakin argon again. Can't win, but I had the pedal going good there for a few minutes.
I'll get some gas Monday and see if I can get the pedal finally sorted out.
