i highly recommend the gasless migs, the are cheap, and if you spend up to £200 on a half decent one, they do a fairly good job, infact i did a few golf floor pans with mine and it did a tidy job, to be fair i had gas mig experiance, not much but enough to know what i was sort of doing, gasless spits more and is harder to get a nice flow, but if you get good at it (and you will) it will make you better as and when you turn to gas mig, infact its like welding luxury. Dont be put of gasless for a first welder though.
