7.1.6 FLUXCORE WIRE WELDING, "FCAW"
•
Connect the ground cable to the positive terminal of the Polarity
Change Board inside the spool compartment.
•
Connect the working cable to the negative terminal of Polarity Chan-
ge Board inside the spool compartment.
7.1.7 MIG WELDING, "GMAW"
•
Connect the ground cable to the negative terminal on the Polarity
Change Board inside the spool compartment.
•
Connect the working cable to the positive terminal of the Polarity
Change Board inside the spool compartment.
7.2 MIG / NO GAS MANUAL WELDING (REF. FIGURE 1)
Before connecting the unit to the mains, verify that all the accessories are correctly installed and mounted
for electric welding (torch, wire spool etc ...).
•
Select Manual MIG Welding function with the Selector Switch (6) on the front panel.
•
Switch the unit ON thru the ON/OFF switch (13) on the back side of the unit.
•
Press the torch trigger to load the wire.
•
Set the welding parameters:
1.
Wire feed speed: use Left Knob (8) to adjust the wire speed expressed in mm on the Left Di-
splay (4).
2.
Arc voltage: use the Right Knob (7) to adjust arc voltage value (no load) from 11V to 35V.
•
Bring the torch close to the work piece and press the trigger
1.
Wire feeder Slope-Up Time (Min. to Max. speed transition time), adjustable with the poten-
tiometer located inside the access panel (16).
2.
At the end of the Slope-Up Time, the wire feed speed reaches the value adjusted with the Left
knob (8).
•
To stop welding, release the trigger. The arc stays ON accordingly to the set B.B.T. (Burn back time).
B.B.T. is the amount of time that the weld output continues after the wire stops feeding. It prevents the
wire from sticking in the puddle and prepares the end of the wire for the following arc start.
7.3 SYNERGIC MIG WELDING (REFER TO FIGURE 1)
•
Select the MIG Syn function thru the Selector Switch (6) on the front panel.
•
MIG Synergy functions permits the operator to get the optimal welding parameters simply setting the
thickness of the material to be welded (Left Knob -8-). Once this parameter is set, the synergic fun-
ction automatically adjusts the wire speed and the welding voltage allowing the operator to balance
this last value if necessary with the Right Knob (7).
•
Switch the unit ON thru the ON/OFF switch (13) on the back side of the unit.
•
Press the torch trigger to load the wire and check that the gas is flowing from the welding torch.
•
Select the thickness of the material to be welded using the Left Knob (8).
•
Adjust the arc voltage using the Right Knob (7) if necessary. Possible variation is +/-5V on the base
value adjusted by default ( "0" on the display). Bring the torch close to the work piece and press the
trigger.
1.
Wire feeder Slope-Up Time (Min. to Max. speed transition time), adjustable with the poten-
tiometer located inside the access panel (16).
2.
At the end of the the Slope-Up Time, the wire feed speed reaches the value adjusted with the
Left knob (8).
•
To stop welding, release the trigger. The arc stays ON accordingly to the set B.B.T. (Burn back time).
B.B.T. is the amount of time that the weld output continues after the wire stops feeding. It prevents the
wire from sticking in the puddle and prepares the end of the wire for the following arc start.
7.4 ALUMINUM WELDING
The machine needs to be set up as follows:
•
100% ARGON as welding protective gas.
•
Ensure that your torch is set up for aluminum welding:
1.
The lenght of the torch should not exceed 3m (it is advisable not to use longer torches).
2.
Install a teflon wire liner (follow the instructions for the replacing of the wire liner).
3.
Use contact tips that are suitable for aluminum wire and make sure that the diameter of the contact
tip hole corresponds to the wire diameter that is going to be used.
•
Ensure that drive rolls are suitable for aluminum wire.
