摘要： A soldering apparatus, in particular a reflow soldering apparatus, for continuous soldering of printed circuit boards along a transport direction, having a process channel including a preheating zone, a soldering zone and a cooling zone, having fan units for circulating process gas in the process channel, wherein the fan units each comprise an electric fan motor and a fan wheel, and having at least one apparatus element, wherein the soldering apparatus can be operated in an operating mode in which the fan motors are controlled in such a way that they are operated at a constant or largely constant rotational speed, as a result of which process gas is conducted through the at least one apparatus element and is then drawn in again by the respective fan units. At least one and preferably a plurality of current measuring units are provided that, in the operating mode, measure the current strength consumed by the relevant fan motor over time, and in that at least one evaluation unit is provided and configured such that a control signal is generated by the at least one evaluation unit if the relevant measured current strength falls below or exceeds a threshold value.
