Chassis Welding - Methods

[gtipping]

As part of my preparation for that time when I can start on my chassis, I have signed up to a welding evening class which will cover gas, arc, MIG and TIG.

From what I have read here and on other forums its seems that for a lot of self builders MIG is very popular. I was wondering what methods folk on here have used for welding their chassis and the reasons for their choice?

Cheers
Geoff.
