WELDING BAR TEST
The welding is not regular or there are some points not sealed: verify the bag is clean and
dry ( if the bag is wet or greased, the seal cannot be done correctly).
The vacuum is loose after few days in a bag under vacuum: it is a tipical bag problem with
little holes; the machine works correctly.
