2, a supporting seat is arranged in its underpart, between the lever arm contact (13) of the microswitch (6) of supporting seat and its center of gravity opposite side, forming the area that long 4-10cm, a width is wider than flatiron is 10-20cm ²Supporting surface, make flatiron place desktop steady.Flatiron supporting seat bottom surface is apart from flatiron axis 3.5-4cm, and the handle tail bottom is apart from desktop 2.5-4cm, makes to hold, when putting flatiron, an activity space is freely arranged.

3, handle is provided with potentiometer (10), regulates flatiron power 20W-80W.

4, on the handle power switch is set

5, LED pipe (9) is arranged on the handle, it is red, green monitors respectively the high and low level of flatiron.

The incoming line of power supply can design front end (12 ') input at handle, also can be arranged on the tail end of handle.

Beneficial effect

1, good welding performance: welding is fast, the sinusoidal crest shape of solder joint light, and tensile strength, toughness, ductility are good, and element is not overheated impaired.

2, the good welds performance that has 20W, 30W, 40W, 60W, 80W popular style, welding stage electric iron function concurrently and possess.
