Description

Technical Field

[0001] This utility model relates to the field of electric welding machine technology, and in particular to an electric welding machine with a protective device. Background Technology

[0002] Electric welding machines are generally classified into two types according to the type of output power: AC power and DC power. They utilize the principle of inductance, where the inductance generates a huge voltage change when the circuit is switched on and off. The high-voltage arc generated when the positive and negative poles are momentarily short-circuited melts the welding material on the welding rod, achieving atomic bonding between them.

[0003] Currently, when existing devices are stored, dust can enter the inside of the socket, contaminating it. When the plug is inserted into the socket, the contaminated socket can cause corrosion or short circuits. Therefore, a welding machine with a protective device is proposed. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a welding machine with a protective device, which has the following beneficial effects:

[0016] 1. This welding machine with a protective device, through the setting of protective components and snap-fit ​​components, allows for the following operation: Pulling the snap-fit ​​plate moves the snap-fit ​​pin, which in turn moves the snap-fit ​​post out from inside the protective plate. At this time, the torque spring resets, causing the protective plate to rotate, allowing the plug to be inserted into the welding machine body. For storage, rotating the protective plate puts the torque spring under torque, releasing the snap-fit ​​plate causes the snap-fit ​​spring to reset, and the snap-fit ​​post inserts into the protective plate. The protective plate protects the welding machine body's connector, preventing dust from entering the connector during storage, thus preventing contamination, short circuits, and corrosion, and extending the welding machine's service life.
