I cant belive how many times this subject has been dicused on this forum, its like debating wich is better fish or meat
, I think its a matter of buget & what each builder feels more comfortable with . I use all three methods of welding at work & each one has its pros & cons but if i get to choose I´d go for TIG 9 out of 10 times so if i´m welding a big thick walled tank i would go for Mig but for the finer jobes it would be TIG.
