Maintenance Tips for Your Seelye Plastic Welder
Plastic welders are an essential piece of equipment for working on bumpers, grilles, headlights and other plastic parts. To ensure your plastic welder provides years of performance and durability, follow a few quick, simple maintenance tips.
When it comes to maintaining your plastic welder, it depends on which welder you have purchased. Seelye, Inc., one of the leading manufacturers of hot air plastic welders since 1953, has prided itself in developing a very user-friendly welder. The Seelye models require just a few regular steps to keep them operating at full efficiency.
Ensure Proper Air Flow
The most important step in maintaining your welder is to ensure proper air flow. Unlike other welders on the market, Seelye has designed its heating element to heat the air as it passes through the heating element. Forcing the air flow through the heating element produces a truer, more even heat with fewer hot spots, resulting in nicer welds. To ensure the longevity of the heating element, it is imperative that when turning the welder on or off that you remember Air First/Air Last. At no time should the welder’s electrical be on without air running.
It is also recommended to have approximately 90 psi of air from your air source and to reduce it using the Air Gauge and Regulator provided with Seelye’s welders to a minimum of 4-1/2 psi of air or more flowing through the welder at all times when the electrical system is on.
For most plastics, setting your air regulator between 5 psi and 5-1/2 psi will result in a proper weld. Once you have finished welding, turn off the electrical system and allow the cool compressed air to run for several minutes to help cool the heating element.
Keep It Clean & Dry
Another important fact when it comes to the air flow is ensuring the user’s air source is clean and dry. Seelye’s welders, with the exception of the portawelders, all come with an air filter. For some users this is the only filter that may be needed. Others whose air lines are particularly wet or have a lot of debris may require installing additional filters at the air source. Any moisture or debris in the air can, and eventually will, cause the heating element to fail. To keep the air flow clean and dry, make sure to check all the filters and empty any moisture or debris on a regular basis.
Caring For The Heating Element
The heating element is located in the barrel of the welder. In order for the air to flow through the heating element, the element is made out of ceramic. While ceramic is an ideal material, it can be delicate, so the user should be careful not to drop or hit the barrel, which could potentially crack the element and cause it to fail.
If you have purchased Seelye portawelders, there is a black filter cartridge located on the supplied air compressor. It is recommended to unscrew the cartridge from the compressor and remove the mesh / sponge-like filter from the cartridge and clean it out periodically.
Caring For The Tips
When welding, you may notice some plastic melting onto the metal welding tip. Make sure to clean any excess plastic off your tips after each weld to reduce the chance of the plastic clogging up the air hole, which will allow the heat to back up into the heating element and cause it to overheat. It is recommended to use a metal brush, similar to a grill brush, to clean your tips. By cleaning your tips on a regular basis, you will not only protect your heating element, but you will also extend the life of your welding tips.
By following these few simple tips, your Seelye welder should provide you with years of service.
