- Working principle
1.) The magnetic type pipe all-position welding machine (MCU type) (hereinafter referred to as the welding machine) uses 4 magnetic wheels to firmly adsorb the welding trolley on the pipe surface, The magnetic wheel is driven to rotate by DC stepping motor and worm gear mechanism, so the welding trolley can crawl on the surface of the pipe.

2.) The welding machine uses DC stepper motor + Linear guide rail + ball screw to realize longitudinal displacement of the welding gun mechanism, so as to facilitate the alighment of the welding gun to the weld.

3.) The welding machine has a specfic longitudinal displacement to realize the longitudinal swing of the welding gun mechanism so that the welding gun can swing and weld.

4.) The welding machine uses DC stepping motor + worm gear and worm mechanism to adjust the angle of the welding gun mechanism. The radial displacement of the welding gun mechanism is realized by using DC stepping motor + bevel gear + trapezoidal screw.

5.) The welding machine uses the gas shielded arc welding source, the gas shielded arc wire feeding mechanism and the special gas shielded arc welding gun to realize the gas shielded arc filling and the cover welding. If selected with speific welding power supply (such as: Kembe FastMig M420, X350, Migatronic Sigma Select 400), can achieve the backing welding.

6.) The welding machine uses the action control circuit board installed in the welding trolley, the welding control circuit board installed in the welding power supply and the wireless remote controller (for PAAWM-00DC, importing the welding parameters in U disk whcich edited in the computer into the action control circuit board) to realize the welding action control and welding parameter adjustment.
