Very thanks for your effort.
The following are a link to the MIG manual, in the page 17 you can see the external conexions to the board.

The following is a schematics of the board that I have found in internet, please notice that the T3 have not the collector...
Mr. Chuckey,
Thanks for kindly your answer.
2x4.7ohms? this resistence is in the welder chassis and not in the board sketched by me, was documented in the service manual as 2/4.7ohm. In this moment the MIG machine is in other address and now I can not check if are 2 resistences the 4.7 in...
Mr. Chuckey, please excuse me, I have attached the scketch without the references. I have edited it and attached the scketch with references.
Struck me that nobody answered my thread.
I have surveyed the attached circuit from a MIG welder PCB board. I have copied only the circuit that control the push wire motor.
I understand it almost all except the (protection?) circuit constituted by SCR3 and T3.
Please let me your explanations.
It is not clear for me if the signal has a sinx/x shape in the time domain or in the frequency domain.
If you wish attenuate the side lobules with a low pass filter use
y is you signal in the time domain

Pankaj,
The attached file is nice and short Motorola Aplication Note one. I don't know if it will be useful for you. Let me know. Regards. Daniel

Pls, can anyone obtain it? Thanks in advance
Dear members, Somebody have or can get the following IEC Standard
IEC 61156-6 Ed. 2.0 (2007-06) Multicore and symmetrical pair/quad cables for digital communications
Dear PaulHolland and Fvm, thanks for your replies.
The ADSL perform equalizing selecting the channels that have better S/N ratio, but do not perform, neither the Dislam, analog impedance matching. Think it is very difficult (I want to do that) adapt more than a decade.
Please forget the ADSL...

Dears members,
I need your advise, because I wish to design for my thesis of magister in data networks, a cuadripole programmable electronically, which can adapt, from 24kHz to 1100kHz, an impedance (the ADSL transmission line to user house, which sees the Dislam from...

lqdjdy, I have assembler code for the 8051 intel family (not C), but it is in my work place.
Please if you have interested remember me on Friday to the danielr@invel.com.ar

Re: ENVELOPE DET.
The diode detector efficiency is the ratio between Voutput(DC average)/Vinput(RF peak).
This quanty depend of the resistence of the load. If this resistence is zero, logically the efficiency is null. If the R=infinite, the efficiency aprox. to 1.
A tipical design value is...
