A rotatable drum holds substrates to be tinned by a solder wave immersion process and is incrementally rotated at a low speed to position the substrates in the immersion tank and thereafter rotated at a predetermined time, temperature and rate of speed to remove the excess solder centrifugally from the substrate. The shaft S (Fig. 1) of drum D is mounted in a pair of cantilever members, such as member 1 (Fig. 2) affixed to a support frame bar 2. A scissor linkage 3, also affixed to bar 2, adjustably raises and lowers the drum D relative to the level of the solder wave S of the solder immersion tank T, as indicated by arrow A.
