The new Hakko FR-830 is a compact and low cost solution to preheating printed circuit boards. The FR-830 incorporates the same higher performance and FR-803B integration feature as the FR-820 but with improved durability over all previous Hakko hot air preheaters. The integrated self-resetting overheat protection, high pressure fan, and convex outlet reduces heat buildup and prevents blockage of the outlet, and the angled heater tube pretects the heating element from damage caused by debris that may accidentally drop inside the heater opening.
