    Instruction Manual Introduction The Triad Extreme Seam hot wedge welding machine is designed for in house fabrication of a wide range of flexible membranes. This includes, but is not limited to, PVC, PP , PE, LDPE, Urethane, etc. Thickness of material that can be welded will vary also with product. Normal range is 5-100 mil thick- ness and can be supported or non-supported material.
  • Page 5 Instruction Manual Intended Use The Triad Extreme Seam Welder is a hot wedge welding machine intended to heat-seal weld- able thermal plastics such as: •Vinyl (PVC) laminated and coated fabrics •Vinyl (PVC) and Polyurethane (PU) films •Polyurethane (PU) and Polypropylene (PP) coated fabric •Polyethylene (PE)
  • Page 6: Chapter 2 Material Set-Up

    Instruction Manual Material Setup Material should be laid out as flat as possible, either on the floor or table depending on how you set up your fabrication area. With most material and especially thinner goods, it is prefered to pull out the wrinkles or pull taunt.
  • Page 7: Chapter 3: Operating Instructions

    Instruction Manual Operating Instructions The following procedures should be followed only after you have followed the Wedge Adjustment and Guide adjustment procedures. 1. Pull up on Red Power Switch #3 to turn machine on. The Green Power Light #4 will go on with a one second delay.
  • Page 8: Chapter 4: Material Guides

    Instruction Manual Material Guides All Guides shown below are included with the purchase of the standard machine. Each guide will give you a specific type of weld and more. You can only use one guide system at a time. The Top Guide will be used with all three different welding functions, overlap, hem and prayer welds.
  • Page 9: Chapter 5: Welding

    Instruction Manual Welding Overlap Weld Attach Overlap Guide #1 to base plate with the two screws provided. Loosen screw (A) to adjust bottom side of overlap for proper alignment and re-screw. Hem Weld Slide Hem Guide #2 onto the three stainless rods up to the outer Horn Guide #3 (Diagram #1), leaving enough area between the two so material will slide easily.
  • Page 10 Instruction Manual Prayer or Fin Weld Position the Prayer Guide #5 under the Welding Horn, placing the key way into the slot. Fasten with screw provided once proper alignment is completed. Front Guides Front Guides #6 are adjustable to pre-align material before you reach the welding process. This will help the operator in feeding material into machine properly.
  • Page 11: Chapter 6: General Maintenance Pages

    Instruction Manual General Maintenance General maintenance should be performed annually to your Triad Extreme Welder. Chain tension should be checked to alleviate excessive wear to the chains and sprockets. Using a foaming chain lubricant will cling to the chain and extend chain life.
  • Page 12: Chapter 7: Wedge Cleaning And Honing Pages

    Instruction Manual Wedge Cleaning and Honing For accurate welds and longer wedge life, the wedge should be cleaned and honed on a regular basis. CLEANING: Wedge cleaning should be done daily. There are two ways to clean the wedge. 1. With the Pressure Rollers in the up position and the wedge in the weld position, use the Brass Brush provided and clean wedge top and bottom.
  • Page 13: Chapter 8: Wedge Adjustment

    Instruction Manual Wedge Adjustment Proper wedge alignment is essential to achieve a proper weld. Units are preset at the factory. Sample welds should be made prior to actual use of the machine. If sample welds are good only on one side or the other, or only partially welded, this means the wedge is not aligned or square to the rollers, and alignment adjustment is needed.
  • Page 14 Instruction Manual Wedge Adjustment (Continued) 2. Swing Wedge Handle #2 in this will engage wedge with rollers. The wedge #4 should rest or fit snug into the rollers #3 on both sides and should be centered. CHAPTER 8 WEDGE ADJUSTMENT Page 14...
  • Page 15 Instruction Manual Wedge Adjustment (Continued) 3. To center wedge between rollers, turn screw #5, this will fine tune wedge up and down. Only a 1/8 or 1/4 turn is necessary. Do not overturn. Move Pressure Roller Handle up and down slowly to check centering adjustment.
  • Page 16 Instruction Manual Wedge Adjustment (Continued) 5. Wedge Stop Screw #9 will stop travel of wedge when positioning wedge in weld position. Loosen Locknut #10 , turn Adjustment Screw in or out to proper position. The edge of the wedge should fit snug and square into the rollers on each end. Make a test weld before proceeding with job.
  • Page 17: Chapter 9: Wedge Replacement Pages

    Instruction Manual Wedge Replacement The wedge should be replaced when honing and adjustment is no longer effective. If heater failure occurs after a period of time, the heaters may not be easily removed. The wedge and heater will most likely have to be replaced together.
  • Page 18: Chapter 10: Wedge Installation Pages

    Instruction Manual 10.0 Wedge Installation Install wedge on wedge mount arm along with lead bracket using two screws (note insert photo). Position heater wires properly on lead bracket and gently close tabs to secure. With wedge in engaged position, use zip ties to collect heater wires together.
  • Page 19 Instruction Manual 10.0 Wedge Installation (Continued) Using clip & screw, attach around heater wires and posi- tion to body of Triad. Do not fully tighten. Electrically connect hot wedge to receptacle on body of Triad. When connected, make com- fortable bend of heater wire and position properly in clip.
