Unlike a tripod, the Whaley Soldering Platform from Eurotool has no obstructions, providing 10 inches of clearance. The unit consists of 2 screens, one measuring 6” x 6” and the other 6” x 9”, which slide in and out of the apparatus. Two sets of screens are included: a pair of fine mesh screens and a set of heavy mesh/heavy duty ones. Plus, the Whaley Soldering Platform is reversible. Replacement screen sets are also available and listed below. Ships flat with instructions included. Patent pending.
