PURPOSE:To facilitate maintenance by providing an opening having a skirt in the periphery on the bottom of a case to hold an inert gas atmosphere and making a molten solder vessel movable vertically to set it on this opening. CONSTITUTION:The opening 4 is provided on the bottom of the case 3 of the soldering device 1. The skirt 5 is provided along the periphery of the opening 4. The molten solder vessel 2 mounted on a vertically movable stand 7 is pushed up, immersed in molten solder and connected to this skirt 5. Consequently, the soldering device 1 can be sealed, outflow of inert gas and inflow of the outside air can be prevented and soldering work can be performed stably. The vertically movable stand 7 is lowered and foreign matters in the solder vessel 2 can be easily removed. The maintenance is facilitated. |
