S3: when first welding electrode (25) need be changed, can start first electric telescopic handle (15), first electric telescopic handle (15) can drive box (38) through miniature bearing (39) and remove to the rear side, when trigger bar (24) and box (38) contact, can drive box (38) and overturn, and flitch (37) are gone up in the L shape then collided in box (38), and flitch (37) are overturned in driving L shape, accessible swash plate (42) drive second welding electrode (43) and overturn when flitch (37) are overturned in the L shape, and insert in the middle of welder (23)'s inner chamber.

S4: simultaneously, second electric telescopic handle (29) start, when second electric telescopic handle (29) move to the left side, can drive two reciprocating plate (27) through two regulating plate (35) and overturn to the outside, and plectane (33) move to the left side, with two gyro wheel (32) contacts, drive two returning face plate (31) upsets, first electric welding rod (25) drop this moment, and second electric welding rod (43) and first splint (26) and second splint (30) laminating, second electric telescopic handle (29) restart afterwards, and move to the right side, press from both sides second electric welding rod (43) tightly.

S5: finally, when flitch (37) upset in the L-shaped, can drive lifter (41) upset, lifter (41) can drive fly leaf (40) and overturn to expose the discharge gate, second electric welding rod (43) of box (38) inner chamber then get into the inner chamber of baffle box, and slide to the inner chamber of bell jar through gravity, because second electric welding rod (43) are the toper setting, consequently can stably place, can not drop, realize stablizing the reloading.
