Hey yall I'm a newbie to this forum and just had some questions about a hf-251 d-1 that I just got. I have been on and off welding since 2008 when I got out of school so I know how to weld and all that. Its just that I have never use this machine or anything like it. So my questions are: can I use it by it self? I have the mig spool gun for it and the tig stuff for it too. The only thing I need is the argon cylinder. I am most likely to use the mig more than tig so if I could just use it for that is it possible without a generator welder?? Any input would be helpful.. thanks
