Hot-air Welder LC-3000D Hot-air Welder & Jointer & Guns

Upgrade design of LC-3000C, offers better use experience and more stable performance.  Especially heating gun, integral mold opening, makes wind more powerful. Updated control system, easy replacement and more precise temperature control. Wind outlet with higher density provides better dustproof effect and longer lifetime.

1. Digital temperature control system with sensor and LCD screen, adopts advanced PID technology, guarantee accurate fluctuation±1℃ visually and welding evenly.

2. Developed industry gun with imported wire, high-temperature resistant, rapid heat-dissipation, durable with long service time.

3. Auto-dormancy is user-friendly, effectively extend service service life. Even if forget to turn off the power, the machine still will enter dormancy and energy-saving state automatically.

4. Laser, handrail and LED light, helpful for accurate positioning, flexible direction adjustment even in night or at uneven surface.

5. Walking automatically, wind and temperature could be adjusted according to different thickness.

1.First, make the picture smooth and tight, take welder to accurate (about 2-4cm), fixed edges with tape or glue on the ground.

2.Set and adjust temperature: connect power, turn on the temperature knob (the golden knob)until it clicks, and then press▲(▲for up ▼for down). Generally, the temperature is between 350-400℃，To check whether the temperature ok, we can take some waste banners to aligned nozzle, If melted immediately, it is the suitable temperature. If not strong, try to increase, if too hot, reduce temperature as below:

3. Set walking speed:Then turn on waling knob to adjust the speed, generally between 3 from 4.

4. Start welding:When actual temperature reaches that you set, we can begin to weld. Pull heat gun to left , machine will work automatically.

At begin,we should take one pc banner up, then put nozzle between two banners as photo shown:

5. During welding, let hot air nozzle between two overlap pieces. And be sure hot air nozzle and Rubber wheel walk in straight line. If not, please adjust by hand.

6. Finish welding: Pull heat gun to right, machine stops walking, then turn off the yellow button(temperature knob), but before cutting off the power, please wait until actual temperature below 50 ℃, or it would damage heat system.

1. Don’t use it in rainy day, keep workplace dry, flat and safety of fire. We would suggest professional technical person operates the machine, it is forbid that someone uses it without specific knowledge.

2. Please pay attention: To protect heat element, we add Automatic Dormancy function, if not used welder over 10 minutes, machine would enter dormancy state. Just press the ‘Reset’ button or put the operation handle to right, can reback to work, but need 1 minute to raise the temperature.

3. Beginner can use waste banner to test and find proper temperature: take a small banner close the nozzle, if hot melt quickly, the temperature is OK, not strong or burnt, we can increase or reduce temperature accordingly. We can also record the temperature for this thickness. Next time,based on this data, we just need to increase or reduce the temperature depends on real thickness.
