"MIG welding is the most difficult of all manual processes to master"
This quote comes from Richard Finch's book Performance welding,Motorbooks Powertech series.I agree entirely,because most MIG welders reach a certain basic level and do not improve much.I suggest that anyone that is serious about improving their MIG welding purchase this book ,written by a hot rod and aircraft enthusiast.
MIG welding is complex and quite a science and before you change wire speeds ,diameters ,gases etc one needs a basic understanding of what is happening,this book explains it well and I highly recommend it if you wish to improve your welding with MIG.
Anyone reading this who is a competent Manual Arc welder (stick) would be much better off using arc welding on these light tubes,faster (it would take longer to get one refill bottle than remove the slag on the entire chassis),the welders and consumables are cheap and the finished job will be better.In fact the lost interest on a MIG welder would pay for all the manual arc welding rods,grinding discs and hacksaw blades needed for the job.
