How to use a tarpaulin welder (such as SWT-MAT1) to weld aquaculture tarpaulins?

1.Temperature and speed test (important!):

Always test the welding with scraps of tarpaulin first!

Simulate welding on scraps, adjust temperature and pushing speed until you find the best combination:

Temperature too low: material does not melt enough, adhesion is not strong, and it is easy to tear. The weld is hard but not truly fused.

Temperature too high: material is charred, yellowed, brittle, or even burned through. Excessive smoke and unpleasant odors are generated.

Speed too fast: material is not heated enough, melting is not sufficient, resulting in cold or false welding.

Speed too slow: material is overheated and easily charred or deformed.

Ideal effect: ** The weld is flat, smooth, translucent (for PVC), strong after cooling, and the material is evenly fused on both sides of the weld. When tearing hard, the damage should occur in the tarpaulin itself, not at the weld.

Start welding:

Press the front end of the welding nozzle gently on the upper surface of the overlapping tarpaulin, located on the center line of the overlapping area.

Heat and move at the same time: Turn on the hot air switch (usually there is a button on the handle of the welder), and hot air will blow out from the gap under the welding nozzle. Push the welder slowly, evenly and steadily along the predetermined welding line.

Apply appropriate pressure: Apply uniform and moderate pressure downward through the welding nozzle. Too little pressure will result in insufficient fusion; too much pressure may crush the molten material or make the welding nozzle move poorly. The roller design of SWT-MAT1 helps to maintain uniform speed and stability.

Keep the operation stable:

Keep the welding nozzle parallel to the surface of the tarpaulin and move at a constant speed.

Follow the front end of the welding nozzle with your eyes to ensure that it always moves along the aligned overlapping center line.

For long welds, do not pause in the middle. If you need to pause, turn off the hot air after the welding nozzle leaves the material. When you restart, you need to move the welding nozzle slightly back to the welded area to reheat and fuse a few centimeters before continuing.

Handling corners and curves:

At corners, slow down and adjust the welder angle slightly if necessary to ensure that the tip always covers the overlap area to be welded.

Avoid pulling the tarp too much at corners.

Finishing the weld:

After welding to the end, turn off the hot air switch, let the tip stay at the end for a few seconds (using residual heat), and then lift the tip away from the material.

Let the weld **cool naturally** for a few minutes. Never pull or bend the weld when it is not cooled.
