Probe height Lock
Keeps a fixed height setting during the welding process.
Recommended to be used on thicker films, or for when welding film to thin card.
Probe Tip Cooling
Maintains a steady stream of cold air to stabilize the heat build up transmitted from the weld.
This is important to establish a consistent and repeatable weld, especially for long welds.
