hey there. Im a welding instructor and witness a lot of people struggle. BUT, I feel like you should really concentrate on finished smaw. You will develop many basic welding techniques that youll use along the way while tigg'in and migg'in. usually right before someone is ready to test, they come out of a slump. Now im not saying you shouldn't mess around with the other processes on your own time, but I wouldn't recommend just skipping getting certified on your stick. Best wishes,,, you're probably getting a lot closer than you think.
