LECAI WELDING MACHINE

Introduction
This machine is used to weld plastic of  PVC, PE, DHPE, LDPE, EVA, Pp and other plastic materials that can be hot meltted. For the current status of format printing industry,Huge screen  picture requires to be  printed separately and then welded. Side of the picture need to be flaped.These efforts need  pvc welding  machine inevitably.

The original Methods is using  glue such as 502, but the disadvantages are obviously:

1. The cost is very high : a medium-sized printing company costs are up on a million of glue 1 year  and  welding    stuffs wages is high expenditure.

2.The speed is very slow : especially in winter ,the temperature is low ,and it cause welding  efficiency to low.

3. Working environment is bad : Glue is not only smell great, but also is left to the hands and clothing of staff.

4. The effect  is very bad : Welding with glue PVC is easier blistering and wrinkled by the sunlight.

Our welding machine has great advantages in welding PVC. It costs only about 1.5 degrees per hour and can weld 8-15 meters per minute . It need only one stuff to operate。It welding effects is very good because of based on hot-melt lamination theory。Splicing can be rolled up after 20 seconds, so it save space。The speed and temperature is adjustable according to thickness of PVC 。It can be adapted to different types of materials。

The weight of welding machine is only 13 kg  and volume is small。It is the perfect partner  for  Inkjet Printer

ApplicationsLC-3000 Intelligent:It is widely used to weld advertising inkjet fabric, inkjet cloth, light box cloth, Daogua cloth, mesh cloth, tarpaulin and other PVC, PE, DHPE, LDPE, EVA, Pp plastic materials that can be hot meltted。

Characterics

1welding without glue.It replaces the 502 glue and improves the working environment of workers, improve efficiency and quality of welding。It is a low-carbon and environmentally products, it is the inevitable trend of development  in the future。

2The theory is based on digital control constant temperatureIt is equipped with temperature feedback sensor。

The sensor is always monitoring the temperature of the outlet to maintain a constant temperature。It uses advanced PID control technology, automatically adjust the power to make the temperature more constant.,the fluctuation  is within 5 degrees。It makes welding more uniform。It uses zero-crossing trigger control IC, there is no harmonic interference, so no matter how long picture is , mosaic effect will not change。Other similar products in home have many disadvantage 。Manually adjust the firing angle with the analog control knob, harmonic interference is relatively large and leads to temperature instability。They show the temperature and the output voltage are not reflect the true temperature in fact。Their actual temperature changes with the input of the voltage fluctuated, is not constant, and sometimes above the temperature difference of up to ± 50 ℃。So they are cheap but the quality is poor。

3: speed 6-10m per minute。It can set the temperature according to  the thickness of picture self-adjustable the working speed appropriatly。

4: Temperature scope0-500℃。Temperature settings with ▲ ▼ buttons,according to the thickness of picture。

5R & D capacityOur company has all the core technology, the quality of the machineis in control

6power1000-1600W  (After Setting the desired temperature, it will automatically adjust the power according to the desired temperature)

7 Hot air speed of hot air gun 。50-100% of the wind speed is adjustable, so you can fight a thick picture to ensure easier,and the heater parts live  longer。

8Heater Equiped  with  AC  motorand it makes wind stronger, life longer (more than  2000 hours), and cost is low  because only need replace the carbon brush。

9Heating wireThe quality of imported heating wire is more reliable and  longer life。

10POWERDELL  Original Laptop Power,EMC is Good and quality is reliable that meet with European and American standards。

:Operation  steps

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

2:Open the power, turning handle to left  to keep hot air nozzle and the rubber tire is on the straight state。Then turn right black knob to adjust the speed, generally marked on the knob points to the location of 4-5。After setup, turning the handle to right until the hot air out of the ground。

3:Set the temperature degree。Open temperature switch,And turn the golden knob untill it clicks and then follow the button in the end。▲for up ▼for down ,set the desired temperature according to thickness of picture。In general, the temperature is between 300-350℃,Or taking some picture material to aligned nozzle, If it can be  melttde  immediately, This temperature is the temperature you need and to set。Charing is forbidden。

4:Set the temperature degree。Open temperature switch,And turn the golden knob untill it clicks and then follow the button in the end。▲for up ▼for down ,set the desired temperature according to thickness of picture。In general, the temperature is between 300-350℃,Or taking some picture material to aligned nozzle, If it can be  melttde  immediately, This temperature is the temperature you need and to set。Charing is forbidden。

5:In the welding process,if printing material is burnt, the first thing to slow down the speed or Or lower the temperature,This avoids to  burnt picture material,but not increasing speed rapidly, otherwise the machine will  run  too fast to make it can not go straight,this will cause thepicture can not be spliced ​​and damage caused。

6:Before using ,pls identify the degree of your printing material with the parameters of temperature and speed。The speed is too  fast  to burn the picture and too slow to welding strong。Therefore,It is very important that  the temperature and speed are good match。

7:After welding ,turning the handle to right to keep hot air gun from picture competly,then turn off the temperature switch(L eft gold knob untill  it clicks)。No luging  the power cord and turning the power off directly,to avoid heat damage to the hot air gun。After temperature of the machine must be reduced to below 50 ℃,you can r plug the powe or main switch。

8:Prohibition of use in rainy day,the workplace should be dry, flat and safety of fire。Specified person is responsible for the machine using,not know indiscriminate using is strictly prohibited。 Working voltage:110V—220V. Strictly prohibited without permission disassemble,Otherwise your peril。

9:Warranty period is one year, of hot air and heating parts supplies are  Portion, they  are not covered under warranty,but We provide you with accessories at their own expense

10:Random spare parts:a 10m power cable, spare parts of a heater, a  set of manual and CD。

11:Products changing do not notice,Please contact your local agents。Product description is only for reference and does not have the legal effect, the final interpretation are all of the Company。

Ⅵ:Repair and maintenance

Fault Remedy
Temperature is garbled, the actual temperature does not show Check the temperature probe whether the grounding be kept vacant nozzle。View probe is broken, repair the sensor line.
Temperature not rise Check whether the fuse heating parts, heating parts replacement if the fuse。
No power Check the wiring is solid or not, protective tube burst。
Scratch the screen Adjust the nozzle and parallel ground,keep the right lateral of  wind mouth form the ground 1mm
Speed ​​out of control Replace potentiometer (black knob)
Welding is not strong Rise temperature degree or slowspeed,Adjust the nozzle parallel with the ground。。

Maintenance equipment to be cut off the power,maintenance should by the professional and technical personnel
