1.turn on the power switch, select a certain temperature and speed, take a few presses totest welding, because of the ambient temperature, the thickness of the material is not thesame, the welding selection temperature of the same material is different, in the case ofthe speed (about 2m/min) unchanged, the selection temperature from low to high temp--erature (about 250° C-350 C) slowly adjusted to determine the best welding effect.
2.Trim the edge of the material to be welded straight, face forward, overlap the leftbottom and right top.
3.after determining the temperature and speed, the material to be welded is insertedbetween the two presses, so that the fuselage is parallel to the edge of the mother village.and the press rod handle can be welded by itself.
4.when the material is welded to the end, the press rod handle is pressed down in timeso that the upper and lower press wheels are in a separate state.
5.the welded material and another material into a "T" lap welding method (Figure 1),the hot knife side of the bypass close to the welding mark diagonal cut length of about150mm
