4.0 Principals of Heat Sealing

Hot Air:

The heat required for the welding operation is created electrically by two heating elements located inside the heat element housing. The hot air temperature ranges from 100 to 1350 Degrees Fahrenheit or 25 to 730 Degrees Celsius.

Speed:

The speed of the weld rollers determines the amount of time the heat is applied to the material being welded. The slower the speed setting the more the material will be heated. To achieve the best weld, a minimal amount of heat should be applied to the material while still achieving a full weld. Too much heat will cause distortion of the material while not enough heat will prevent the material from welding.

Pressure:

The pressure of the weld roller is the final step when creating a weld. The pressure of the weld roller compresses the heated material together completing the welding process.

Summary:

When heat sealing, the correct combination of heat, speed and pressure will allow you to achieve a properly welded seam.

5.0 Start Up Procedure

Start Up Procedure

  1. Ensure that all cabinet doors are closed and locked.

  14. Once material is to the cell with the puller rollers, use the HMI to close the puller rollers.
  15. Turn on any remaining functions that will be needed for the welding process.
  16. Your machine is now prepared to weld!

6.0 Shut Down Procedure

Shut Down Procedure

  1. Clamp the material to the output end of the machine. This ensures the material will be in the proper position for the next production.
  2. Ensure the heat button is off. The temperature should start decreasing.
  3. The machine will not shut off immediately! The compressors will go through a 3-minute cool down cycle to allow the heat elements to cool off. These will then shut off.
  4. Ensure the tension from the unwinds are released by forward or reverse jogging the unwind. This will ensure the material does not pull out of the machine or guides when the circuit breaker is cut off and the pullers disengage.
  5. After the compressors have shut off, turn the main power disconnect to the off position.

Air Filter Cartridge

The Miller Weldmaster Moduline Gen II Multi Sealer has an air compressor that supplies airflow to the heat elements. Periodic cleaning and changing of the air filter cartridge is necessary to maintain sufficient airflow. Insufficient airflow or any impurities in the airflow will shorten the life of the heat elements or the onboard compressor.

Clean the air filter weekly for best performance. Once you can no longer read the black text on the side of the filter cartridge it is time to replace the filter.

Common Components

Heat Elements

The heating elements used by the Miller Weldmaster Moduline Gen II Multi Sealer are rated for 1000 hours of use at 1000 degrees F (537 degrees C). Although longer heat element life is possible with proper maintenance, 1000 hours is the average. If the heat elements fail prematurely, contact a Miller Weldmaster representative before replacement.

Chains

The Miller Weldmaster Moduline Gen II Multi Sealer has several chains that are used to drive weld rollers and pullers. Although not a high maintenance item, chains should be inspected once a month to ensure there is not excessive corrosion, rust, or dirt. Also inspect for any looseness or slack. If needed, lubricate chains once a month with 80w – 90w gear oil.

Adjusting the Upper Unit Weld Roller Drive Chain

Upper Unit

When tightening the upper unit chain, you must check the weld roller for play. The weld roller should only move back and forth an 1/8 of an inch. Loosen the nut on the tensioning bolt. Once the nut is loosened turn the bolt clockwise until the weld roller does not move. Then back off the tensioning bolt counterclockwise until the weld roller achieves the 1/8 of an inch play.

Main Drive Chain

The main chain to the clutch should be a little loose. Take the cover off the top of the head. Adjust the chain by loosening the drive motor mount on the side of the head. There will be 2 idler sprockets. The chain should pull away from the idler sprocket approximately 3/16 of an inch but not enough to come off the teeth. If the chain is too tight, the clutch will not work properly.

Changing Thermocouple

The Moduline Gen II Multi Sealer uses a thermocouple to read the air temperature just before it reaches the nozzle. The typical life expectancy of a thermocouple varies. The thermocouple should be replaced if the machine does not maintain a constant temperature of +/- 2 Degrees F (+/- 1 Degree C) or the heat elements burn out prematurely.

16.0 Welding Tips

Welding Tips

Bad Weld: This is not a good weld. Although the fabric is somewhat welded, it is not what would be considered 100%. One of two things must happen for this weld to become excepted. Either the speed must be decreased, or the heat must be increased.

Good Weld: This is a good weld. The fabric is welded 100%. You can see that the fabric is delaminating over the entire width of the seam.

Upper Weld Roller Going Too Slow: This is an example of the upper weld roller going too slow. The green panel goes through the left side of the welder and the yellow panel goes through the right side. The upper weld roller is going slower than the bottom weld roller. This shows in the wrinkling of the bottom or left panel. The upper weld roller clutch pressure needs to be increased.

Upper Weld Roller Going Too Fast: This is an example of the upper weld roller going too fast. The green panel goes through the left side of the welder and the yellow panel goes through the right side. The upper weld roller is going faster than the bottom weld roller. This shows in the wrinkling of the upper or right panel. The upper weld roller clutch pressure needs to be decreased.

Too Much Shrinkage: This is an example of too much shrinkage in the material. Many thermoplastics tend to shrink when heated. This is caused by overheating.

Perfect Seam: This is an example of a perfect seam. There is no waviness, wrinkles, or puckers.
