Banner welder
When picture size more than printer printing width, need to split the picture to some part, after print out then weld them together. Usually use 502 glue to joint them by hand, but this way is disadvantageous, like: slowly, after long time the glue is not hard, the glue will dirty picture, work by hand hard to control the quality etc.

Usually use 502 glue to joint them by hand, but this way is disadvantageous, like: slowly, after long time the glue is not hard, the glue will dirty picture, work by hand hard to control the quality etc.
Our sapiential hot air welder machine can resolve the problem successfully. Our machine no need glue, use hot air to melt the material and joint them together; it can move itself in work; with sensor in the welder nozzle, can control the work temperature accurately; Work temperature, speed, and fan motor speed are adjustable; the body made of steel, very strong; little dimension, 41*25*20cm, light weight, just 15kg, can bring it to anywhere easily.
1. Application field
Use for welding PVC, PE Banner and other material can be hot melt, like flex, PVC cloth etc.
2. Main technical details

3. Advantage
No need glue, use hot air to weld;
Temperature, speed, fan motor speed are adjustable;
Welder nozzle has a sensor, can make the true temperature accurately;
High welding quality.
4. Operation procedures
1). Before hemming or welding, leave 30-40mm wide overlap edge for connection the two disjunct surface pieces, immobilize both ends of each disjunct pieces with something such as stick belt or clamp.
2). Turn on the power, according to quality and thickness of the PVC banner, consider the ground circumstance, set the proper termperature and speed, adjust the suitable hot-air blowing rate, wait for machine hot up around 2 minutes.
3). Bring up the machine, place the rubber wheel at the end of the overlap edge.
4). Turn the handle to left down, insert the welder nozzle into the gap of two overlap pieces, then the machine will moving and seaming automatic.
5). During welding, use the gripe to align the moving direction, let the upper piece edge be in touch with the inner side of the welder nozzle.
6). After the machine go pass the overlap edge to the end, the two disjunct pieces will be joined together, then turn the welder handle to right, it will stop moving.
7). Turn off the heater switch, wait the gun come to cold, then turn off the power supply is ok.
8). Notice: To prolong the electrothermal heater, after work it is strongly advice that cooling the heater at first, then turn off the power 5 minutes later. In case of the power suddenly be off, should handle the welding gun away firstly, and close down the temperature knob, nextly consider the problem of power supply.
9). To get better satisfied bonding effect, the ground of the overlap pieces should be smoothly, hard and heat resistive. We suggest that the operator may do some more test and practice using some samples of the pieces to get the suitable speed and temperature and hot-air blowing rate before operate it for seaming formally.
