Do you know how to operate an automatic welding machine? I'll walk you through the procedures.

1. Operator Qualification Requirement

Operators must hold a valid welding operation certificate before taking post.

2. Pre-Startup Preparation

(1) Ensure adequate ventilation at the workplace to avoid hypoxia caused by welding shielding gas.

(2) Do not stack flammable materials in the working area to prevent fire hazards.

(3) Check whether the welding machine shell is properly grounded and if cables have any damage.

(4) Inspect all wiring terminals for looseness and burnt parts caused by poor contact.

(5) Confirm sufficient shielding gas supply and check gas pipelines for leakage.

3. Equipment Operation Procedures

(1) Install the electric heating gas pressure reducer as required.

(2) Preheat the reducer for 5 to 10 minutes before use.

(3) Open the cylinder valve slowly at about 5 degrees per second; the pressure gauge pointer will rise gradually and stop at the standard reading.

(4) Switch on the air circuit breaker of the electrical cabinet to power on the machine. Check for electric leakage on the cabinet and machine body; resolve leakage issues before proceeding.

(5) Check if indicator lights on the side of the electrical cabinet work normally; troubleshoot any abnormalities before further operation.

(6) Verify lubricant level inside the reduction gearbox; follow the reducer maintenance specification if any abnormality exists.

(7) Run the machine idle to check for abnormal noise or overheating in the gearbox, gears and motors; eliminate faults before formal operation.

(8) Select the correct working mode on the operation panel: "Debug" mode for manual control; "Auto" mode for programmed automatic welding.

(9) Set proper parameters including worktable rotation speed and rotation direction, then start the machine for formal welding.

(10) Function selection and partial parameter adjustment can be completed on the welding machine control panel.

(11) Each function on the control panel has a corresponding indicator light which lights up when activated. Special reminder: The over-temperature warning light will turn on if the machine overheats; shorten operation time or shut down the equipment immediately in this case.

4. Shutdown Steps

(1) Close the gas cylinder valve and release residual gas inside the pressure reducer until pressure gauge pointers return to zero.

(2) Press the stop button, then turn off all power switches and gas supply switches in sequence.

(3) Fully clean the machine and ground to keep the workplace tidy.
