Questions & Answers

Everyone has questions. Tell us yours.

Q: Sometimes when I lock down my Auto Clam it releases too soon. Any suggestions?

A: If you can't get your heat press to stay closed, there may be too much pressure or the round magnet on the adjustment arm may need cleaning. Check with your manufacturer.

Q:After being on and not used for several hours, my Auto Clam shuts off. Is this a feature that can be changed?
A:The Auto Clam has a manual safety feature with an automatic shut off if the machine is idle for two or more hours. This feature cannot be disabled. Refer to your owner's manual for information on how to reset.
Q:How can I check the pressure setting on my heat press?
A:Lower the upper platen and lock it into place. Heat presses with a pressure readout will display the setting on the front panel.
Q:The handle on my Auto Clam heat press only releases one or two inches, then stops and is very hard to lift. How can I get it to work normally?
A:The gas springs may be loose. A replacement can be ordered from Hotronix®.
Q:What voltage are the Hotronix® heat presses sold in?
A:Hotronix Heat Presses are available in both 110V or 220V.

Hotronix Auto Open Clam Heat Press

Simple to set up and use right out of the box. Auto release is a must. Recommended for small creative businesses in need of heat application who have limited square footage to operate. Hotronix manufacture probably the best heat presses on the market.
