A solder handling assembly comprises a heating portion, a casing, a variable resistor, a connecting member coupled to the variable resistor, and an elastic-resilient member movable from a first state to a second state. The connecting member is rotatable relative to the casing and is configured to adjust a resistor value of the variable resistor when the connecting member is rotated relative to casing. When the elastic-resilient member is in the first state, the connecting member is prevented from rotating relative to the casing. When the elastic-resilient member is in the second state, the connecting member can be rotated relative to the casing. |

1. A solder handling assembly comprising:
a heating portion; a casing; a variable resistor configured to change a temperature setting of the heating portion; and a connecting member coupled to the variable resistor, the connecting member at least partially disposed within the casing, the connecting member rotatable about a rotational axis relative to the casing and configured to adjust the temperature setting by the variable resistor when the connecting member is rotated relative to casing, wherein the connecting member includes an elastic-resilient member movable from a first state to a second state and further includes a first engagement device fixed on the elastic-resilient member, wherein the casing includes a plurality of first opposing engagement members, each first opposing engagement member fixed on the casing at a position different from that of the other first opposing engagement members, wherein when the elastic-resilient member is in the first state, the first engagement device is engaged to any one of a plurality of the first opposing engagement members coupled to the casing, the engagement device prevents the first engagement device from rotating from the position of the first opposing engagement member to which the first engagement device is presently engaged, to another one of the plurality of positions, and prevents the connecting member from rotating about the rotational axis relative to the casing, wherein when the elastic-resilient member is in the second state, the first engagement device is disengaged from the plurality of positions of the first opposing engagement members, the disengagement allows the first engagement device to rotate from the position of the first opposing engagement member to which the first engagement device was previously engaged, to another one of the plurality of positions, and allows the connecting member to rotate about the rotational axis relative to the casing, wherein the elastic-resilient member is in the form of an arm radially extending from a central portion of the connecting member, and the first engagement device is fixed at an end of the arm, wherein the connecting member includes a key receiving portion configured to receive, from outside the casing, a key projection having a shape that fits within the key receiving portion; and an operating member, wherein the operating member includes the key projection configured to push the elastic-resilient member from the first state to the second state. |
