PURPOSE:To constrain strenuously the solidification of flux and the generation of harmful substance by heating a liquid at the lower heater temp. compared with the conventional one. CONSTITUTION:The commodity heating equipment performs a welding work for a commodity 2 by heating the commodity 2 at adequate temp. The liquid 1 having the boiling point equivalent to said temp. is contained into the tank 3 of which bottom wall 3a is inclined in horizontal direction. The commodity 2 is then descended into the tank 3, the liquid 1 is heated upto the boiling point by the heater 4a-4c provided with close contact to the bottom wall 3a of the tank 3 and a steam is generated. The commodity 2 is heated by this steam and the steam 5 is recovered by its liquifaction with condensation by the cooling coil 6 provided on the upper part of the tank 3.
