Step 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.
Step 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.
Step 3 :
Bring up the machine, place the rubber wheel at the end of the overlap edge.
Step 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.
Step 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.
Step 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.
Step 7 :
Turn off the heater switch, wait the gun come to cold, then turn off the power supply is ok.
Step 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.
Step 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.
