2.3.2 MMA Operation method
1. Once installed according to the above method and the main switch is on, the machine is
switched on, the display is lighting and the fan is working.
2. Select the welding mode on the front panel to “MMA” and set the welding current according
to the welding process.
3. Observe the polarity when connecting. Phenomena such as unstable arc, excessive spat-
tering and electrode adhesion if inappropriate polarity is selected. To resolve this problem,
replace the quick plug connection.
4. Select a larger cross-section cable to reduce the voltage drop if the secondary cables (weld-
ing cable and ground cable) are long.
5. Adjust the welding current according to the type and size of the electrode, secure the elec-
trode, and perform welding with short-circuit arc welding.
Note: This table is suitable for mild steel welding. For other materials, consult related materials
and welding process for reference.
2.4.1 MIG Installation method
1. Plug the welding torch into the output socket “ ” on the front panel, and tighten it. Thread
the wire into the torch manually.
2. When welding the solid wire, Insert the earth cable plug into the negative socket “-” on the
front panel, and tighten it clockwise. connect the wire feeder to “+” terminal on the middle
panel, and tighten it.
3. When welding the fl ux wire, Insert the earth cable plug into the negative socket “+” on the
front panel, and tighten it clockwise. Connect the wire feeder to “-”terminal on the middle
panel, and tighten it.
4. Fix the welding wire coil to the rack axis on the wire feeder; make sure the hole of the wire
feeding wheel matches well with the bolt on the rack axis and the welding wire diameter. Un-
fasten the screw on the wire-pressing wheel, and make the wire into the glove of the wire feed
wheel, press the wire tightly, but not too tight, and then thread the wire into the torch. Press
the” wire feeding” button to feed the wire out of the welding to torch.
5. Tightly connect the gas hose, which come from the back of the machine to the copper nozzle
of gas bottle.
2.4.2 MIG Operation method
1. Once installed according to the above method and the main switch is on, the machine is
switched on, the display is lighting and the fan is working.
2. Select the welding mode on the front panel to “Manual” and adjust the welding voltage and
wire feeding speed according to practical needs to get the desired welding voltage and
welding current. Or select the “Synergic” mode when the setting is done automatically by the
machine.
3. Press the welding torch switch, and welding can be carried out.
4. Cut off the gas 1s after the arc is stopped.
2.4.3. CuSi - (Silicon Bronze) MIG Brazing
MIG brazing uses the same installation and operation methods as MIG welding mode.
When setting up the machine for MIG brazing, there are several key components that must be
correct to achieve the best results possible.
- It is critical that 100 % argon shielding gas is used with silicon bronze wire.
- Since silicon bronze wire is softer than steel, “U” rolls are recommended, but “V” rolls will also
work.
- Polarity should be set to DCEP.
- A Te fl on liner is recommended due to the softness of the silicon bronze wire, but a regular steel
liner will also work.
