So now I have one coolant hose which goes to the large connector on the torch lead and the other hose goes up into the jacket going to the torch. Which hose is which and which should be hooked up to the coolant in and out connectors? Thanks!
Coolant to the torch goes into the loose line and returns from the line that has the large DINSE plug. Did you download the online manual? I have heard the the ones in the box are not that good.
