Reply:I have no idea, but I will tell you, that based on what you read on here you can probably cross the everlast off your list. Some are good and some are bad, but if you have to ship that thing back over seas to the states or wherever to fix it; it's probably going to take awhile and cost a lot. They don't have good customer service. Unless they are local to you, which I have no idea.Did you look at the one from eastwood? It's a reputable company so I'm sure they will ship it, just not sure how much.Did you also look around for a used one locally?Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:All I am willing to say about those listed is avoid multifunction welder/cutters.If you are truly trying to save the expense of hiring a professional, at least try to buy professional quality machinery. That means going to your local welding supply and getting a demo on something they carry and support. With the right equipment and support you could become very proficient and save thousands not hundreds.Good luck and don't let the giant rabbits bite.Last edited by shovelon; 01-18-2013 at 01:30 AM.Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li  ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea.
Reply:It's been a while, but I seem to recall lots of issues with MOFSET based units in the past. I think many of the imports moved away from MOFSETS and towards IGBT based machines. I'll let the electronics expets comment more on this.
