Dent Fix DF-900A Alu-Spot Aluminum Dent Repair System (DF900A)
The idea here is that you have everything you need for aluminum repair, within easy reach in a self-contained system. The tools lock away so they do not wander the shop and become contaminated with steel particles.
As you probably know aluminum panel repair is a different process than that for steel panels. Aluminum is a softer material it stretches easily. That is why it is alloyed with magnesium or silicon in cosmetic panels. We include two different alloys of stud pin for bonding with the various panels.
Aluminum is also work hardened; meaning when it is stamped into shape it becomes stronger. When the panel is bent in a collision it becomes stronger still. Flex it too much and it breaks or cracks.
Sometimes in order to relieve this over-hardening and be able to pull the damaged area needs to be heated the allow the metal to release. The panel must always be heated to about 400 degrees while under pull in order for the panel to set in new position. Hence the inclusion of an infrared thermometer and digital temperature set heat gun to heat the panel. A self-locking squeeze puller makes it easier to pull and heat at the same time. This squeeze puller can pull on one or several pins. For heavier pulls a leverage puller and for lighter finesse pulls a single pin hand puller are included.
Put steel particles into the aluminum panel and you will start the electrolytic process of galvanic corrosion. The aluminum will corrode around the steel contamination ruining the paint on your finished jobs. In order to avoid this a separate set of working tools must be maintained. That is why we have included a separate set of hammers, dollies, and nylon shaping tools, body file, and an Air drive for 3M Roloc discs. Again the tools lock away in the rolling tool station, also included.
Aluminum forms a thin coating of aluminum oxide after being exposed to the air in a little as an hour. This oxidization has a much higher melting temperature than the original aluminum material. We have included a stainless steel brush for last minute cleaning.
The capacitor discharge welder is 110 volt powered. Re-charge time for the capacitors is less than 3 seconds. The ground is on the weld gun itself. This leads to a more successful weld due to the close location. The fact that we have two ground points on either side of the weld gun also leads to a more successful weld rate. And of course when working on a roof or the middle of a hood having to attach separate ground leads can cause extra and unnecessary refinish time.
