Receipt of Equipment
When you receive the equipment, check it against the shipping documents, Make sure it is complete and inspect the equipment for possible damage during shipping if there is any damage, notify the carrier immediately to file a claim.
Furnish complete information concerning damage claims or mistake(s) in shipment to Machinery Co., Ltd's Include the equipment identification number along with a description of the parts in question.
Move the equipment to the installation site before uncrating the unit. Use care to avoid damaging the equipment when using bars, hammers, etc. to uncrate the unit.
General safety rules:
Before removing the body of the product, pull out the wire first.
The operator must be qualified accordingly.
The operation can only be controlled by qualified technicians.
The compressed air power must be cut off and turned off before the maintenance operation is carried out.
Electrodes, electrode arms and other secondary conductors can reach very high temperatures and stay high for a long time after stopping the machine. Pay attention to scald.
Preventive maintenance is necessary on a regular basis.
Power Connection:
- Check that the device must be connected to the ground coupler and to the ground. It is in good condition.
- Check if the workbench is connected to the ground connector.
- Ensure that the operator does not have any contact, protection or wet clothing with the metal parts to be welded.
- Avoid contact with welded parts.
- Do not spot weld in very wet places or on wet floors.
- Do not weld with worn cables. Check that the isolation belt does not have a default cable or that the connection is loose.
- Please turn off the device before replacing the electrode.
- Please disconnect the equipment directly before it is controlled or repaired.
Protection of Eyes and Body:
-
During welding, wear leather gloves, welded apron, safety shoes, welding protective clothing, arc filtering and radiation projective helmet or glasses. The operator must protect his eyes during rubbing and hammering.
-
Don't wear rings, watches or jewelry. It can cause burns.
- All protective board must be in good condition and in proper position. In the absence of eye protection, do not look at the welding arc. Protect the environment near the product from projection and reflection.
Welding Fume:
Welding operations can lead to the emission of toxic smoke and harmful metal dust. The equipment should be installed in covered areas with smoke inhalers. Operators must wear smoke masks. Welding materials must be cleaned.
Pay Attention to Fire:
- Check whether sparks cause fires, especially in the vicinity of flammable materials.
- Check that the fire extinguisher is not far from the operator.
- Place the equipment where there are pneumatic devices.
- Do not weld on a container with flammable and lubricant, even if it is empty.
- Do not weld in an atmosphere filled with flammable gas or fuel vapor.
Electromagnetic Compatibility:
Near the welding site, check:
- There are no other power cords, control cables, telephone lines, radio or television reception equipment, watches, mobile phones, magnetic cards, computers or any other electronic device.
- No active medical devices (pacemakers, acoustic prostheses) were used around (at least 3 meters).
