DOSA’s Professional Powder Coating Gun Repair Process
To help customers reduce unnecessary time and effort, DOSA uses the following structured repair process:
Step 1: Contact and Initial Consultation
Customers can contact DOSA through the technical hotline 0969 429 222 (Zalo) or send photos and videos showing the equipment fault via Zalo. The team will review the information and discuss possible causes and an appropriate next step.
Step 2: Powder Coating Gun Inspection
After the initial information is confirmed, customers may send the equipment to DOSA for direct inspection (for customers outside Ho Chi Minh City). For nearby customers, an on-site inspection may be arranged according to the equipment and schedule.
Step 3: Quotation and Deposit
After inspection, DOSA provides a proposed solution and an itemized quotation. Repairs begin only after the customer confirms the scope of work, expected replacement parts, cost and completion time.
Step 4: Repair and Payment
The technician carries out the repair within the confirmed scope. If additional work is identified beyond the original quotation, DOSA informs the customer and obtains approval before proceeding. After completion, the gun is checked for powder feeding, powder output and operation of the relevant components before handover; post-repair support follows the agreed conditions.

What Are the Signs of a Faulty Powder Coating Gun?
- No voltage at the gun tip, possibly due to a damaged high-voltage circuit or a broken electrical wire.
- A fault in the powder feed system, spray nozzle or air supply may cause no powder output or weak spraying.
- Uneven powder adhesion on the workpiece may result from an electrode fault or loss of voltage.
- Electrical short circuit in the gun, accompanied by a burning smell; the control board should be inspected.
- The control display does not turn on, possibly due to a software or controller fault.
