1. Contact Tip (Core Consumable Part)
Routine Replacement Cycle:
When operating with low current (≤150A), it is recommended to replace the tip every 48 hours.
For high current (≥180A) or robot welding, the replacement cycle should be shortened to every 12 hours.
If the bore wear exceeds twice the wire diameter or the weld bead deflects by more than 1mm, it must be replaced immediately.
Material Impact: Chrome-zirconium copper contact tips are more durable than copper and are suitable for robot welding.
2. Other Consumable Parts
Arc Chamber/Shield
Replace the tip every 1-2 months, or immediately if carbon deposits or cracks are detected.
Welding Cable
Inspect the insulation every 3-6 months and replace if damaged or deteriorated.
Nozzle
Replace the tip every 1-2 months under normal use. Replace sooner if spatter is severe. Wire feed hose
Depending on wire quality, replace every month or if wire feeding is difficult.
III. Special Working Condition Adjustments
High-intensity operations: The contact tip replacement cycle may be shortened to a few weeks.
Robot welding: Replacement must be strictly performed according to the procedure to avoid misalignment.
IV. Maintenance Recommendations
Before each model change or production run, inspect the contact tip for wear and fill in a replacement record.
Retain spare parts (e.g., 20-30 contact tips and 2-3 nozzles) to meet unexpected needs.
