Hot Air & Plastic Welding FAQs | HotAirTools.com

Question 1

What is the difference between the Leister Triac ST and the Leister Triac S?

Accepted Answer

What is the difference between the Leister Triac ST and the Leister Triac S? The Leister Triac ST is the upgraded version of the Leister Triac S (which is no longer in production). Some of the improved differences with the Triac ST are:• Ergonomic handle (which is a composite of plastic and rubber, whereas the Triac S was plastic only).• The Triac ST weighs less than 2.2 pounds, lighter than its predecessor.• The ST uses state-of-the-art components.• Manufactured with only 35 spare parts; whereas the Triac S had 53 parts (which you can still purchase).• Most of the parts unique to the Triac ST are less expensive than those of the Triac S.• Less expensive (by $65) than the Triac S.

Question 2

Are nozzles and rollers included with a Triac plastic welder purchase?

Accepted Answer

No, our nozzles and rollers are sold separately. We do offer plastic welding kits at an incredible value that include nozzles, rollers, accessories and the hand tools you need. You can shop plastic welding kits to save on bundles.

Question 3

Do nozzles for my old Triac S fit on the newer Triac ST?

Accepted Answer

Yes, any nozzle that fit the old Triac S plastic welding tool will fit on the Triac ST tool.

Question 4

Do you have spare parts for hot air tools, blowers and heaters?

Accepted Answer

Yes, we do. We offer spare parts for the Triac S, Triac ST and Hot Jet S for purchase online. We also offer spare parts under the Parts Center for other hot air hand tools, heaters and blowers. Let us know which spare parts you need, and we can order them for you. Call us directly at 800-241-4628

Question 5

What are plastic welding rods? I have found some generic rod that I can use for my plastic welding project. This should work, right?

Accepted Answer

Plastic welding rod is rods of plastic made from the type of thermoplastic that you are trying to weld. When welding plastic it’s important to use like materials so the weld is strong. Example HDPE rod to HDPE sub straight. Therefore, it is imperative that you know what materials you are working with. By not using like for like rod material that matches the sub straight the welding rod will not stick/weld. Learn more by visiting our welding rod page.

Question 6

Is this Hot Air Tools?

Accepted Answer

We get asked this question a ton. Hotairtools.com is a shared website between Eastern region Heely-Brown and Western region Assembly Supplies Co., which have both been Leister authorized sales and service centers for over 35 years!

Question 7

How long of an extension cord can you use for a Varimat V2?

Accepted Answer

We recommend 100ft maximum 6/3AWG from a generator to a spider box for the Varimat V2. Voltage drops if cord is over 100ft. Then from the spider box to the tool, it’s 100ft maximum of 10/3AWG.

Question 8

How big of a generator do I need for a Varimat V2?

Accepted Answer

The suggested minimum heavy-duty generator capacity required when using a Varimat V2 is 10kW. Never run drills, screw guns, radios etc. on the same generator as the Varimat. The generator must have less than 10% total harmonic distortion.

Question 9

Why is the air blowing out only one side of the nozzle on my Varimat V2 or Uniroof?

Accepted Answer

The nozzles are designed to blow this way intentionally on both the Varimat V2 and Uniroof. The air blows out of the small part of the nozzle, while the air dam is designed to keep the hot air from escaping and pushes it towards the overlap edge.

Question 10

I have a CH6060 and need another tool or spare part.

Accepted Answer

CH-6060 or CH-6056 are postal codes for Switzerland. This is not the article number. You can find the article number on newer equipment located on the name plate; it has 6 digits separated by a period e.g (141.228). To locate an older equipment article number, look for the tool type (TYP), with Voltage and Wattage. If you would like to learn more about the highly searched Leister number we wrote a special blog explaining what Leister CH-6060 is with visuals on where you can find it on your tool.

Question 11

What is plastic welding?

Accepted Answer

Plastic welding is a process of uniting in a molecular bond two compatible thermoplastics generally with the aid of heat. In other words, thermoplastics (a polymer plastic that can be melted and shaped several times) are joined together by melting the surfaces and pressing them together. You can also learn more about the benefits and advantages of plastic welding.

Question 12

What are three main steps in Plastic Welding?

Accepted Answer

The primary steps in plastic welding are pressing, heating and cooling. • Pressing: The application of pressure, which is often used throughout both the heating and cooling stages, is used to retain the parts in the proper orientation and to improve melt flow across the interface.• Heating: The purpose of the heating stage is to allow intermolecular diffusion from one part to the other across the faying surface (melt mixing).• Cooling: Cooling is necessary to solidify the newly formed bond; the execution of this stage can have a significant effect on weld strength.

Question 13

What are some tips for welding thermoplastics?

Accepted Answer

Welding is the process of uniting sur¬faces by softening them with heat. The number one rule of welding thermoplas¬tics is you must weld like-plastic to like-plastic. Reference our welding rod page for which material you may need. Be sure you are in a well-ventilated area, pre-heat your gun for at least 2 minutes, make sure your surfaces are clean and double check what type of plastic you are welding. Here we share even more tips on how to weld plastics.

Question 14

Ultrasonic Plastic Welding.

Accepted Answer

Ultrasonic plastic welding is the process of joining thermoplastics using heat from a mechanical motion with high frequency. The mechanical motion, along with applied force, creates heat with friction between two plastic materials.

Question 15

Ultrasonic Film & Fabric Processing?

Accepted Answer

The way you get ultrasonic film and fabric is exactly how it sounds. You bond fabrics and films containing thermoplastic materials together. Materials using this method are: Acrylics, nylon, polyester, polyethylene, polypropylene, polyvinylchloride, and urethane. Industries such as automotive, apparel, packaging and medial benefit from this ultrasonic film and fabric process.

Question 16

How do you choose the right Hot Air Blower or Heater?

Accepted Answer

To make the decision, first you need to take a few factors into consideration: volume of air flow, compatibility of air sources, built-in thermocouple, and built-in temperature controls. A hot air blower is exactly how it sounds; it blows hot air, generally, in a specific direction. Like a hot air blower, a hot air heater also is exactly as it sounds; it creates heat, which can heat enclosed spaces. So of course, both hot air blowers and hot air heaters heat things or spaces, but what’s the actual difference between the two? Let’s take a look at the differences and talk about how you should choose the best heater for you.

Question 17

How to Shrink Plastic with Hot air?

Accepted Answer

Hot air is ideal for the processing of shrink films and shrink tubes because when plastic is heated it curls and bends. There are two main areas when it comes to heat shrinking. Heat shrinking within packaging technology and heat shrinking in electrical engineering.Leister hot air blowers and heaters are used in all areas in which hot air is conceivable in the manufacturing process: mechanical engineering, auto, food, packaging and building industries.
