What kind of torch are you using? Best to use a torch with a push/pull system. We had exactly the same problem till we started using this system. Still does it now and again but nowhere near as bad. Try and keep it as straight as possible as well. What size wire are you using?

Right......Egidio...uhm, how do i put this...
I think we have a little problem here with your english, i've read your posts a few times now but i can't really understand how the setup of your welder is...

Is it a robot? what settings do you use for the Esab?
Please try to be as clear as you can!

Pienso que tenemos un pequeño problema aquí con su inglés, yo ahora hemos leído sus postes algunas veces pero no puedo entender realmente cómo es la disposición de su soldador…

I used a program to translate this it is called Babelfish.
Utilicé un programa para traducir esto que se llama Babelfish.

Thankyou Egidio! Can you post any pictures of your welds?
Are you using pure Argon? (shielding gas)
What kind of aluminium parts are you welding?

¡Gracias Egidio! ¿Puede usted fijar cuadros de sus autógenas? ¿Es usted argón puro que usa? (blindando el gas) ¿Qué piezas un poco de aluminio es usted que suelda con autógena?

I hope the spanish translation makes any sense to you!
