Notes:
1. Recommendation temperature on welding bead around 150℃.
2. Operator should strictly follow with operation specification. Amps and speed of welding should be maintained in order to avoid metal deformation by overheating.
3. 2 hour drying process is required (300-350℃) before use.
The above suggestions are for reference purpose. Evaluate and determine the situation of the scene before starting the wielding process.
