I picked up an older Panasonic "Sharpshooter" that does dual function - stick & wire feed (MIG), but I prefer the MIG to arc because most of the welding that I do is with light material - less than 1/4". THe gasless "MIG" systems are usually stepped controlled for voltage/wire-feed, whereas the more expensive units are variable voltage/wire-feed which gives you better control based on the material you are welding.
TIG requires the use of both hands to operate and that can be a problem in some cases.
Regardless of which you decide on using, each has its advantages/disadvantages, but one thing remains the same, use protective gear.
Good luck with your adventure into welding.
