I had a cheap (not ozito but similar chinese brand) mig welder. all i can say is that the dial never leaves full power, and it needs more. It can weld about 1.5mm steel really well for 2 mins before overheating and cutting out as a 'safety feature' to protect itself. this was the most frustrating thing i have ever experienced. took at least 20 mins to half an hour to cool down.
turns out it only had a 15% duty cycle at full power (only 120amps). The duty cycle is how long it can weld for every ten minutes. eg 50% means 5 mins every 10 minutes. I upgraded to a 175 amp italian made TIG/Stick welder and am in love with it. Beautiful welds and never cut out on me yet. Since i got it I havnt gone back to the MIG once.
My advice is to buy a welder with a good duty cycle. I would suggest 100% at 100 amps, which probably means about a good quality 170 amp welder (or a crappy 200+ one). unfortunately this means at least $1000 as far as i can tell, although u might be lucky on ebay. I guarantee its a tool ull want to keep, and if you dont you can always sell it on to the next person for a slight loss. think of the loss as 'rental' on the welder
its probably more than you want to spend, but something like this could be the one for you. https://www.machineryhouse.com.au/Produ ... kCode=W180http://cgi.ebay.com.au/Allmax-Magnum-Mi ... 215wt_1139
or if you want to spend only $300 ish, you could get something like thishttp://cgi.ebay.com.au/NEW-MIG-195-AMP- ... 4252wt_905
but it only has 60% duty at 70 amps, but at least u apparantly get 195 as a maximum.
I made the mistake of thinking i could get away with a cheap/small welder, i'v now fixed that mistake. if you want a lifetime investment, get a good one
It would have been extremely dangerous... except for the fact he was drinking at the same time.
