Welding Machine Operation Guide

Connect the welding machine to the power supply specified by the equipment correctly, ensure the power interface is in good contact and free of looseness; then turn on the power switch of the welding machine, open the machine cover, check that the internal lines of the equipment are normal (no damage or aging), and confirm that the machine is in a normal operable state.

According to the welding requirements, load the appropriate flux-cored wire, straighten the wire to avoid bending; feed the wire into the wire feeder through the wire feed tube, adjust the wire exposure length to 2-3 cm, align the welding torch with the wire, and adjust the angle to prepare for welding.

Connect the welding torch switch and ground wire firmly to ensure good grounding; select the appropriate welding mode according to the thickness and material of the workpiece. For thin workpieces, lower the current; for thick workpieces, increase the current to ensure sufficient welding penetration. At the same time, keep the welding voltage stable to avoid unstable welding caused by voltage fluctuations.

Press and hold the red switch on the welding torch to start the welding machine. The machine will automatically feed the wire. Operate the welding torch at a constant speed to ensure uniform weld formation. Choose spot welding or continuous welding according to needs, and avoid defects such as slag inclusion and air holes. If any abnormality is found during welding, stop the machine immediately for adjustment.

The rated input voltage of the welding machine must comply with the equipment specifications, usually including 110V, 220V and 380V. Select the corresponding voltage according to the power grid standard of the use scenario to avoid equipment damage caused by voltage mismatch.

The rated output current of the welding machine ranges from tens of amperes to hundreds of amperes. Industrial-grade welding machines have a rated output current of up to 500A, which is suitable for heavy-duty welding such as thick plates and large workpieces, and can meet the needs of long-term high-current welding.

The insulation level of the welding machine is usually Class B or above to ensure safe use and avoid electric leakage. The cooling methods are divided into air cooling and water cooling: air cooling is suitable for small and medium-sized welding machines, and water cooling is suitable for large industrial welding machines to ensure stable operation of the equipment for a long time.

Place the welding machine in a dry, well-ventilated and sun-protected location. Avoid placing it in a humid or corrosive environment to prevent equipment failure. If outdoor operation is required, set up a rain shelter to protect the welding machine from rain and moisture.

Ensure the welding machine is properly grounded, and the ground wire must be firmly connected without looseness or damage. Do not place the ground wire on flammable or explosive items to avoid safety accidents such as electric leakage and fire.

Operators must wear complete protective equipment, including welding masks, protective gloves, protective clothing and safety shoes, to avoid eye damage caused by arc light and skin burns caused by welding sparks. It is strictly prohibited to operate the welding machine without protective equipment.

Summary: Standard operation is the key to ensuring welding quality and operational safety. Operators must master the
