All products in the welding machine series require electricity, and the medium frequency spot welding machine is no exception. During the use of electricity, measures to prevent electric shock are particularly important. So how do we operate to prevent electric shock in intermediate frequency spot welding machines? Next, we will give you some precautions when using an automatic spot welding machine.
Firstly, the insulation of the intermediate frequency spot welding machine tongs is reliable. Prohibit the use of welding tongs without shells to prevent accidents. This is a point that automatic intermediate frequency spot welding machines and other series of spot welding machines must undergo strict inspection before leaving the factory. At the same time, the outer shell of the automatic intermediate frequency spot welding machine is grounded. The purpose of grounding is to prevent the spot welding machine from accidentally coming into contact with the casing and causing electrical injury. In any case, it is indispensable. The grounding body of automatic spot welding machines can widely use natural grounding electrodes, such as water pipes and reliably grounded building metal structures. However, it is strictly prohibited to use flammable and explosive pipelines as natural grounding bodies. If the resistance of the natural grounding electrode exceeds 4 Ω, use an artificial grounding electrode, otherwise it may cause electric shock accidents or even fires. If you want to move the automatic spot welding machine, you need to cut off the power. Dragging the cable to move the spot welding machine is not allowed. In case of a sudden power outage, the power should be cut off immediately to prevent electric shock.
Furthermore, it should be pointed out that construction personnel should also take appropriate measures to prevent power outages. Gloves must be worn when replacing welding rods. If clothes are soaked in sweat, it is not allowed to lean against metal objects to prevent electric shock. If you want to repair the intermediate frequency spot welding machine, disconnect the power switch, which has a clear disconnect gap. Before starting the repair, use a pen to check to ensure that the power has been cut off.
