Parts Desk Insights
Best Use Case: Use the AT-300 when you’re performing a two-part adhesive installation and need consistent dispensing from the correct 50ml Weld Mount cartridge system. Select the correct plunger ratio before dispensing (1:1 for AT-2010/AT-4020; 10:1 via AT-12 for AT-6030).
Common Issues: Most common fitment issues come from using the wrong plunger ratio for the adhesive cartridge (for example, AT-6030 requires the 10:1 plunger). If dispensing performance changes, re-check that the cartridge/plunger pairing matches your adhesive type and verify the correct mating components per the system diagram/instructions.
