Hello All- Trying to troubleshoot our Miller Syncrowave 250 DX tig welder. An employee had used it over the weekend, and now the display is not operating at all. Checked the owner's manaul at millerwelds.com and I'm thinking the best place to start may be the fuses. Does anyone have anything to add that I might find helpful in the process - this is a new piece of equipment (to us) and I want to be careful not to get in over my head. Thanks for your time.
