- MMA configuration
There are two ways of connecting the welding output cable: normal connection and reverse connection
DCEP
It means the workpiece is connected to "+" and the electrode holder is connected to "-". It is often used in manual arc welding
of acid electrodes because of high deposition rate of welding wire and a shallow penetration depth.
DCEN
That is, the workpiece is connected to "-" and the electrode holder is connected to "+". It is often used by manual arc welding
of alkaline electrodes with deep joint welding of weld penetration. In addition, the reverse connection used in alkaline
electrode is good for arc stability.

1) Turn on the power switch of the machine.
2) Set the welding method on the welding power control panel to "manual arc welding".
3) Manual arc welding can only be performed after the output terminal of welding power is reliably connected to the welding
cable when no remote control box is inserted, the welding current is adjusted by the "welding current" knob on the front panel
of the welding power supply, and the thrust is adjusted by the "thrust current" knob on the front panel of the welding power
supply. When the remote control box is inserted, the welding current and thrust are adjusted by the knob on the remote
control box.
4) When welding, please wear leather gloves and safety boots and use light-shielding filters suitable for welding current.
