Re: 130 amp mig welder good enough?
It's not just the quality of equipment ,It's the quality of training of the operator!
I have decades of welding experince (in navy shipyard) were we had every type of welding process known ,and still saw crapie work...prep,prep,prep then stare at it then prep some more. Good mech fit ,well ground filletts, and strong root passes are what most fellows lack . You seem to be on the right track ,tack together for mock up then take project to your brothers and use gas mig for weld out.
Just my two cents...good luck and don't mess around with flash burn wear glasses please!
we few, we happy few, we band of brothers.
for he that shares the road with me shall be my brother. be he nare so vile this ride shall gentile his condition . and pedestrians now afoot will hold there manhood cheap when passed by a motor bike geek
