Hi. I'm new to the forum and just getting started welding. I already have a HF 90 amp flux core welder which should do for much of my small projects. I am in process of doing the DCEN conversion. One question I have is this: I already have a couple of large capacitors and wanted to see if these will suffice or if I need bigger caps. Specs: 17000 micro farad 75 volt. I welcome any advice on this procedure as well. Thanks.
