Mould securing clamp and screw, if eye bolt is screwed out (anti-clock wise) handle clamp will tighten mould clamping.
Handle clamps are an essential part of the welding process for the following reasons:
1. Handle clamps have a vice grip type locking arrangement which allows the operator to free his hands.
2. When repetitive welding takes place the mould becomes far too hot to handle (wear your safety gloves).
3. Mould securing clamps hold hot mould parts to the handle clamp securely, allowing easy cleaning.
