I have a Forney Arc welder, model #C4, Serial #85412, purchased in approx. 1955. It has worked well up until lately. It's very hard to strike an arc & when I finally manage to, it welds for approximately 10-15 seconds and the rod sticks to the work. Also, I can't weld on a lower setting. Can you tell me what is wrong with it and how I can fix it?
Check your input power connections on the primary side of the welders transformer, then if its an infinite control welder check that control,otherwise if it's a plug- in selectable amperage check these connections,it sounds like the infinite control is getting dirty and not passing all the current it shows on the control, also double your O.C.V. on the secondary and see if its with-in welder specs
