Vinova Testimonials
I've used all types, brands, mig, tig, spool guns, arc, and for the money this little guy surprised me, outperformed my expectations, hopefully it lasts, welded for 2 hours straight today right out the box. Only downfall is the fixed whip and lack of ability to run gas. But for a portable 110 mig on a 100 ft extension cord it delivered
Jetsk Jon
This mig welder works great for what it is. It's a light duty welder, and they make no claims for it being anything else, but it's absolutely perfect for most home and hobbyist use.
Jesse C. Benton
I ran weld’s within its duty cycle and it performed perfectly. I’m truly impressed by the little button that adjusts the wire feed automatically. As far as performance, weak. If’n it can put out 80 amps I’d be impressed and if cranked up? Well it just kicks off. Maybe my units defective, idk. Nice even arc below 3/4 power though.
