3.Introduction to front panel of power source

(1) Welding curr. regulator: adjust the welding current while SAW/MMA switch is on the position of MMA, but it will be invalid while SAW/MMA switch is on the position of SAW. The regulation to welding current is realized over the welding curr. Regulator on the tractor’s panel.

(2) Digital meter: show the actual welding current or voltage, and the value is from the Curr./Vot. switch

(3) Curr./Volt switch: be used to switch the current and voltage signal of the digital meter

(4) Overcurr.: be on while the welding current surpasses the maximum value

(5) Overheat: be on while the temperature of the radiator is higher than the set value, and be off while the temperature is lower than t he set value and the welder will recover to work automatically

(6) Over/undervoltage: be on while the net voltage is lower than 260V or higher than 450V, or there is phase missing

(7) Power: show whether the welder is powered-on

(8) SAW/MMA/Gouging switch: be used to switch between SAW and MMA/Gouging

TRACTOR

1. Features

MZ7 automatic submerged arc tractor and power source jointly consist of “automatic submerged arc welder”, which can be used in butt joint, lap joint, and corner joint of middle/thick steel structure. It can weld carbon steel, low alloy steel, stainless steel, and heat-resistant steel, etc.

(1) Front and back wheels of the tractor can move simultaneously, march stably, wide welding range, with diameter of welding wire being Ф3.0~Ф6.0mm

(2) Easy and flexible to do adjustment, integral turning of head and uplifted welding torch

(3) Beam can turn around and uplift

(4) Turnaround and fluctuation angle of the flux container can be adjusted

(5) The wire feeding instrument is equipped with alignment structure, feeding wire stably, good adjustment range, big pull, strong in wire feeding

(6) Print motor is adopted as the wire-feeding motor and marching motor, small default, long service life (the common pilot motor)

(2)The control cable of the welding generator is connected with the input socket of the tractor’s control box

(3)The connector of marching motor and wire-feeding motor is plugged into the output socket of the control box

4.Introduction to control panel of the tractor

(1) Ammeter: show the welding current

(2) Welding curr. Regulator: adjust the welding current

(3) Voltmeter: show the welding voltage

(4) Welding volt. Regulator: adjust the welding voltage

(5) Marching speed meter: show the marching speed

(6) Marching speed regulator: adjust the marching speed of the tractor

(7) Wire-feeding button: press it, the wire will go down

(8) Wire-withdrawing button: press it, the wire will go upward

(9) Marching button: press it, the tractor will march according to the set speed

(10) Marching direction switch: switch the marching direction of the tractor

(11) Stop button: the tractor will stop to march or weld after it is pressed

(12) Welding start button: press it, the tractor will start to weld, and stop after the stop button is pressed.
