no amp control... econotig..

i wish it were that easy!

knob 4 is inactive in tig mode.. its only used for stick welder mode..

Wrong it is not, that is why there is a break down below the knob of how many amps you are running at each number. If you set it to 100 amps on dc when you floor the pedal to max you will get 100 amps but at half pedal it should be about 50 and so on. So if knob 4 is turned all the way up you are getting the least amount of control.

Next thing you did not say what tungsten you are using, what gas you are using. So lets start there.

With Sch 10 stainless I would set my amp knob at 70-80%, gas flow at 20CFH, us 3/32 red tungsten sharpened to a point. Is this what you are doing?

One other thing did you make sure you have gas coming out of the end of the torch?

but why does the manual says

4. Amperage Control

This control does not work in GRAW (TIG) mode. Use control for Stick when Weld Process switch is in stick position

i dont know.. this is confusing.. it even has the stick welding mode icon right under the knob.. eitherway there was no difference when i changed the knob weather i set it to 0 or 100..

just hosed off the entire machine with sensitive electronic parts cleaner.. can beileve i paid 6 bucks a can and it took 2 cans.. should have just went with the brake parts cleaner...

oh well..

machine is about 80% cleaner.. i just made sure i got all the knobs and switches good (the current type selector actually feels alot better now)

anyone have a miller econotig? can you take a picture of the connector for the amp control? do you have the d pin?

[buk]

Your "D" pin appears to be missing on your amphenol, thus no control. Find it and shove it back in.

wiring diagram shows d pin is not used... page 11

Dan,

Not so on the early Econotigs-- as stated in the manual-- that the Knob does not work in GTAW- The FC would be 0-100% of the machine's power.

I purchased my unit in '91 and my conn is the same as yours for foot control eventhough the D is in the plug, it adds K for thumb control which appears to be a ground. Me thinks your problems are typical of the reference you posted.
Good luck

thanks for the pictures..

i guess now my only chance is to find someone whos encountered this problem before and fixed it themselves..

What foot control are you using and how many pins does it have?
Which pins does does it use?

According to the manual you supplied it should be a RFC-14 which has 5 pins (A,B,C,D,E)

pictures are uploading...

its an rfc-14 just like you said with pins a b c d and e

but there is no d pin on the machine!

and the hand control plug has a, b, c, d, e, and k...

and i dont have a k pin on the machine...

[buk]

pictures uploaded..
i flipped the images so you can see the pins corresponding to the machine..

hand control pins a,b,c,d,e, and k



foot control pins a,b,c,d and e



any input would be greatly appreciated
