As you know the 250 ext has had some issues with low end starting/foot pedal operation and have worked with the factory to resolve it. The problem is known and experienced generally by all. We have of course suspended further sales on the unit. We have worked with the factory for a final resolution . We will be returning ALL units in our possession back to the factory. This is a ONE time return being approved by the China import office. Any customer with a 250EXT should call for a refund from us or a exchange for another unit so we can get these back to the factory. The deadline to arrange this is Dec. 5 2012. If you choose to keep your welder, or if you do not contact us by this date, the warranty against part breakage will remain, but the problem will not be resolved any further as we have exhausted our recourse of action on the US side. Please do not delay so that we can definitively resolve this matter that has gone on too long.
