PURPOSE: An electrode tip abrasion alarming device of a welding machine is provided which informs a worker of an optimal tip abrasion timing by the movement of a buzzer or an alarm lamp. CONSTITUTION: In the welding machine where a welding completion switch(i) is connected to supply or cut off alternating current power source of 110 voltage according to the welding completion, the electrode tip abrasion alarming device comprises: (i) a power source lamp(PL1) which is connected to the output side to inform the welder of power source impression; (ii) a timer b contact point switch(bTM) and a relay switch(CR1-1) which are turned on or off through the electric current impressed by the movement of the welding completion switch to impress electric current to output terminal; (iii) a relay lamp(CR) and a timer(TM) which supplies the electric current of the welding machine to the output terminal by the movements of the timer b contact point switch(bTM) and the relay switch(CR1-1); (iv) a relay switch(CR1-2) which is in gear with the movement of the relay switch(CR-1) to switch on or off; and (v) a buzzer alarm lamp(PL2) which informs a worker of tip dressing periodic state of the welding machine by the movement of the relay switch(CR1-2).
