10.0 WELDING PREPARATION
√
Connect the ground cable to the proper female outlet on the bottom right-hand corner of the welder (on some models the ground cable is already
connected). Attach the ground clamp to the bare metal to be welded, making sure of good contact;
√
Make sure that the wire-roller groove in the roller corresponds to the diameter of the wire being used.
√
Plug the machine into a suitable outlet.
√
Open the gas valve on the gas cylinder regulator, (turn knob counterclockwise). Adjust the gas regulator to the proper setting position, turning the
regulator knob (clockwise to reduce the quantity of gas, counterclockwise to augment it). Note: this varies with different metals, thicknesses
and currents.
11.0 OPERATION
The main purpose of SYNERGIC power source is to make the selection operations easier. In the control PCB are stored the optimal welding data,
which can be set by the user selecting the power click, the type of material, the diameter of the wire and the type of welding gas.
1)
Set the desired welding mode by pressing the key (4). the red led will light up in correspondence to the desired mode sliding from the
bottom to the top of the list. The Led lighting has a cyclic sequence from down to up.
2T – 2 time welding. The welding process starts pushing the torch trigger and stops releasing it.
4T – 4 time welding . The welding process starts by pressing the torch trigger after a pre-gas time, it continues even if trigger
is released and stops when this is pressed and released once again after a post-gas time.
2T-R – 2 time welding. The welding process starts pushing the torch trigger and stops releasing it. On this mode, the motor slope
up is set on zero.
PULSED – pulsed welding with pulsation time adjustment – This mode can be activated only in manual mode and works only with the spool gun.
Turning the knob (5) you can set the pulsation time, the display will view a number between 5 and 102, the minimum and maximum settings.
In this way you will obtain a weld deposit which is made of different repeated welding spots, one above another, which create a single weld
bead. It is used for thin layers, to avoid overheating and the perforation of the workpiece, without affecting the welding penetration.
2)
Select the desidered welding material pressing the key (7):
Fe - iron
Inox
Al - aluminium
CuSi – copper – silicon alloy
3)
Select the desidered wire diameter pressing the key (8) :
0,6 – 0,8 – 1,0 – 1,2
4)
Select the desidered gas type pressing the key (9):
CO2 – carbon dioxide
ArCO2 – argon + carbon dioxide (misture)
Ar - argon
WARNING: the power source helps you to choose the gas, leaving only the suitable gases for the selected welding material.
5)
Before starting welding verify that the wire speed balancer (6) is positioned in the middle of the regulation scale, the red led over the knob
has to light up.
If you are not satisfi ed with the wire speed set by the machine, you can change it maximum +20% by turning the knob clockwise and -20%
by turning it counter clockwise.
6)
Select the welding voltage turning the switch, according to the workpiece thickness. Low for thin pieces, high for thicker ones.
The display should view the wording "RDY" to show that the settings are correct and the power source is ready to work.
Warning: to choose the most suitable welding voltage, it could be useful to make some tests on the working piece, starting with low
voltages until a good welding quality is obtained. Pieces of the same thickness may require different welding voltages, depending on the
welding position (butt weld, angular weld...)
11.1 DISPLAY
In "no welding" condition (no load), the display views two wordings: "Err" that means ERROR or "rdy" that means READY. By "RDY" display the unit is
ready for welding; by "Err" display unit doesn't work, set welding parameters are not correct.
The wording "Err" is displayed when:
- the Ø of the selected welding wire cannot be welded.
- the Ø of the selected welding wire is too small compared with the welding voltage selected.
- the Ø of the selected welding wire is too big compared with the welding voltage selected.
The display views the real welding current. After welding the display will view the welding current value for a maximum of 5 seconds.
