I will totally agree with the fact that the newer Millermatic welders with auto settings are awesome. I have one, and it works very well.
That being said, you don't need automatic settings. My first welder was a Hobart Handler 135. It had manual settings. It took very little time to get used to adjusting those settings. Start with the recommended settings for the gauge of metal you are welding, and go from there. Weld on scrap for practice. It takes a lot of practice to get GOOD at welding, but it takes very little time to get competent. Find some videos on You Tube and watch them. DO NOT TRY TO GO THE FLUX ROUTE! welding with gas is MUCH easier. Use a combo of CO2 and Argon.
Wait. Why am I bothering. It's been almost 3 weeks since the OP posted his question, and he has not been back.
