[0033] Reference Figure 1-Figure 7 The invention discloses a safety welding machine suitable for various environments, comprising a welding machine housing 1, which constitutes the main structure of the safety welding machine. A group of symmetrically arranged handles 2 are arranged on the front and rear sides of the top of the welding machine housing 1. The handles 2 are arranged in a pull-able manner, so that the device can be carried easily. Four movable brackets 3 are arranged at the left and right outer walls of the welding machine housing 1. The lower end of each support beam 32 is provided with a rotating wheel 4. When used in various environments, the device can be lifted and matched with the rotating wheel 4, and can be moved freely to improve the balance of the device, and prevent it from tipping over on bumpy sections, puddles and other sections, causing damage to the device. Heat sinks 5 are respectively arranged at the left and right corners of the front end of the welding machine housing 1, and the inner walls of the plurality of heat sinks 5 are interconnected with the inner cavity of the welding machine housing 1. The heat sink 5 is composed of a plurality of heat sinks, and a gap is reserved between each two heat sinks for air circulation inside the device, accelerating heat dissipation, and preventing the internal high temperature of the device from being unable to be discharged in a timely and effective manner when the device is working.

[0034] In the present invention, a switch 10, an adjusting knob 11 and a display 12 are respectively provided on the front inclined wall of the welding machine housing 1.
