but from close-up it looks pretty below amateur.
Besides, as you mentioned, I need to do those weld tacks again to improve the overall strength.
I wish you live close-by.

@GQtdauto, any chance you can give me a rough idea how long a D size argon bottle would last mate?
I mean when it come to making a typical 8 x 5 cage trailer?
I'm referring to MIG welding, of course.
