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

The Hot-air welder LC-3000C, economical with stable machine performance, is equipped with handle and red laser pointer. It is widely used  to weld thermofusible materials like PVC, PE, DHPE, LDPE, EVA, PP and etc.

In view of the current situation of the spray painting industry, huge pictures need to be printed in stages and then welded together. Generally, the picture needs to be edged, which inevitably uses the welding machine.

1. Small machine body, light and easy to move and operate.

2. Laser positioning line makes welding more accurate.

3. Equipped with temperature feedback sensor to monitor and keep constant temperature.

4. Adopt advanced PID control technology, adjust the power automatically to guarantee constant temperature, fluctuation within 1℃.

5. DC fan with strong wind and more air, welded effect more stronger, avoid leakage.

6. Equipped with handrail, standing to operate, more user-friendly.

7. Auto-dormancy function protects heating element and extends machines' lifetime.

8. Speed 8m/min satisfies fast welding large banners. Only one worker can operate the machine.

9. Adopt the principle of hot fusion and pressing, no need glue. It consumes only 1.5 degrees per hour and the effect is beautiful and strong.

The initial welding method is with 502 glue which has obvious disadvantages:

1. High cost. The glue cost for a middle--sized companies is more than 10,000 RMB/year and the wages of workers are high.

2. Slow speed.Especially in winter,low temperature results in low welding efficiency.

3. Terrible working environment. Glue not only has a bad smell, but also remains on the employees’ hands and clothes.

4. The outdoor printing cloth with glue is easy to foam and wrinkle after being irradiated by sunlight and the glue will harden after solidification, which affect the appearance and packaging.

1. You should adjust the temperature and speed according to the thickness of banners.

2. Fix the cloth on the smooth ground to make sure the best result.

• 01

  Fixed patch ends

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

  

• 02

  Set Temperature

  Set temperature:connect poTrend, turn on the temperature knob (the golden knob)until it click,and then press▲(▲for up ▼for down). In general, the temperature is between 350-400℃.To know the temperature is ok, we can take some waste banners to aligned nozzle to test, if it can be melted immediately, this temperature is the one you need and to set. If not strong just increase temperature, if too hot,reduce temperature.Check photo below:

  

• 03

  Set Wind Speed

  In general, we put wind speed to the largest. So just put wind speed to the Maximum is ok.

  

• 04

  Set Walking Speed

  Then turn on waling knob to adjust the speed, generally marked on the knob points to the location between 3 from 4.

  

• 05

  Start Welding

  When actual temperature of the display screen reaches temperature that you set, we can begin to weld. Put operation handrail(at end of the machine)to left, machine begin to work automatically. At begin of weld, we should use one hand to take one banner up, then put nozzle between two banners, check photo:

  

• 06

  During Welding

  Let hot air nozzle between two overlap pieces. And be make sure hot air nozzle and Rubber wheel walk in straight line.If not, please adjust by hand. Check photo:

  

• 07

  Finish Welding

  Turn the walking handrail to the right, machine stop walk, then turn off the yellow button(temperature knob), but before cut off the power, please wait until actual temperature below 50 ℃, then we can cut of the main poTrend, or it would be damage heat system.

  

• 01

  Don’t Use It In Rainy Day

  The workplace should be dry, flat and safety of fire。The machine should have technical person to operate， it is forbid that someone use it without specific knowledge. Working voltage：110V—220V. Strictly prohibited without permission disassemble，you should be responsible the result yourself.

• 02

  Automatic Dormancy function

  In order to keep heat element, we add Automatic Dormancy function,it means if not using welder over 10 minutes, machine would be enter dormancy state. If want it reback to work, just press the ‘Reset’ button or put the operation handle to right is ok, but it needs 1 minute to raise the temperature, so we need to wait.

• 03

  For the first use

  For first user,we can use waste banner to test and find proper temperature, we can do like this: take a small banner close the nozzle, if the banner hot melt quickly, it means,the temperature is OK, it not strong or burnt, We can increase or reduce temperature. We can also write down the temperature for this thickness of banner as sample. In next welding, based on this temperature. We just need to increase or reduce the temperature depends on thickness of banners. Check the welding result:

  Safety instructions

  Plugboard must be grounded wire,when using welding machine. And you mustn’t turn off the machine until the welding machine will completely cool down in a few minutes. Then pull out the plug.

1. Clean the nozzle with copper brush.

2. Clean the air inlet with soft bristle brush.

3. Check the power cord and plugs to avoid any mechanical damage.
