Instructions for use of hot air guns

Below by the hot air gun manufacturer dezhigao Hi Tech Co. Ltd. to introduce the hot air gun operating guidelines:

"1" before use should be sure to have reliable grounding, anti-static tools on the damage of components.

"2" should be adjusted to the appropriate temperature and air volume, according to the different shape of the nozzle and the work requirement to adjust the characteristics of hot air gun temperature and air volume; soldering time resistors and capacitors small components for 5 seconds or so, the general IC rework time is about 15 seconds, BGA rework time is about 30 seconds, big BGA rework time of 50 seconds (such as: white 850B A1130 hot air gun nozzle when the air temperature adjustment of 1 stalls, 3.5 stalls; no air nozzle temperature adjustment of 4 stalls, 4 stalls. Digital display ATTEN850D with A1130 nozzle air volume adjustment 3, temperature 350 degrees; without the nozzle, air volume adjustment 4.5, temperature adjustment 380 degrees.

"3" turn on the power switch to hot air gun is preheated to a temperature stable before welding, soldering iron to use uniform heating element in the element can not reach 1~2CM above; in the rework process, pay attention to the protection of the safety of surrounding components.

"4" nozzle do not force too much, not to beat the table to give a strong iron of impact, avoid heating wire and high temperature glass damage.

"5" high temperature operation should be very careful, do not use hot air guns in flammable gases, flammable objects in the vicinity, pay attention to personal safety, replacement of parts, left turn off and let it cool, long time should unplug the power plug.

When the work is finished, turn off the power switch, then start the automatic cooling time, and don't pull out the power plug in the cooling period of 6.
