Assuming you mean mig ?
for the "odd job" yes for any more no
you are far better off with the refillable bottles, the initial expense is high but pay back is dramatic
most people find the disposable bottle only last 15 -20 minutes and can be empty every time you go to use it once opened.
on the other hand
Have you looked at Mig wire with the flux built in ie no gas !!
for gas welding definately no.
