Soldar metales

Soldar:

* Con electrodos o MMA (Manual Metal Arc welding), el aparato puede ser con transformador (pesa más de 25 Kg) o con inverter (pesa desde 2,5 Kg).
Precios inversor desde 100 euros y 60 con transformador

Polaridad directa: electrodo en el negativo y masa en el positivo.

* TIG -  tungsten inert gas, el tungsten no se consume
No escoria, no salpicaduras. Se puede soldar casi todo típo de materiales.
Se puede empezar con un soldador inverter, los hay con opción TIG pero no es necesario. El de transformador no vale.
Necesitas: inverter, antocha TIG (compatible con inverter), capuchón, difusor, gas (Argón 100%, Helio 100% o mezcla de ambos).
Varillas de aporte (se puede hacer sin aportar).


soldadura MIG/MAG (Metal Inert Gas o Metal Active Gas, dependiendo del gas que se inyecte) también denominada GMAW (Gas Metal Arc Welding o «soldadura a gas y arco metálico») es un proceso de soldadura por arco bajo gas protector con electrodo consumible.

Como arreglarlo, dos aproxmaciones

1) BCEDIT:

- Esto es lo que decías, ¿no?

http://www.tomshardware.co.uk/forum/58615-63-system-config-info-heeeelp

>> So... I went to research - AGAIN - hahah! But God is so good and He have such a infinite mercy that I went to a page that perfectly explained everything I needed to know, STEP BY STEP of what to do in this particulary situation (the guy had the same problem! and - as I saw on the comment's space - a lot of people have this issue as well!). Check it out:
(by the way, his page here: http://nilcemar.blogspot.com.br/2012/04/corrigir-badsystemconfiginfo-no-windows.html)

~~~~ Bad_System_Config_Info ~~~~

1) Start the "inicialization repair" (or installation repair - I dont know the name in English,
I just try to translate but I cant say if this one is the right term to use).
2) It will try to fix the problem without success. Dont worry, go to the "system recovery options"
3) Logon as the adminitrator
4) Go to the "command prompt" and type "bcdedit /deletevalue {default} numproc" (without quots) and press "enter"
5) Now type "bcdedit /deletevalue {default} truncatememory" (without quots) and press enter again
6) Close the prompt screen and reboot! THAT'S IT! It is all that takes to Wind goes normal again!
 After these steps I didnt have anymore problem!!! PRAISE THE LORD! I couldnt get this far without Him!!!
