The utility model provides a portable heat preservation welding machine which comprises a welding machine body, four moving wheels are fixedly installed at the four corners of the bottom of the welding machine body, a push rod is arranged at the top of the welding machine body, telescopic rod assemblies for driving the push rod to ascend and descend are arranged on the two sides of the welding machine body, and supporting assemblies for assisting braking and supporting are arranged on the two sides of the bottom of the welding machine body. Under the action of a brake assembly and transmission of a transmission belt, an extrusion block performs friction braking on the inner wall of a fixed frame, so that the state of a moving wheel is changed, and under the action of a telescopic rod assembly, key structures are switched between the braking state and the movable state of the device, and the states of a supporting assembly and the brake assembly are changed; compared with the prior art, carrying and pushing ar
