5.4.4 HOW TO CHOOSE THE WIRE LINER
Mainly we can have 2 types of wire liners: Steel wire liners and Teflon wire liners.
• The steel wire liners can be coated or not coated: the coated wire liners are used for air cooled torches;
the wire liners which are not coated are used for water cooled torches.
• The Teflon wire liners are suggested for the welding of Aluminium, as they allow a smooth feeding
of the wire.
5.4.5 GAS CYLINDER AND REGULATOR CONNECTION
WARNING: Cylinders are highly pressurized. Handle with care. Serious accidents
can result from improper handling or misuse of compresses gas cylinders. Do not
drop the cylinder, knock it over, expose it to excessive heat, flames or sparks. Do not
strike it against other cylinders.
The bottle (not supplied) should be located at the rear of the welder, securely held in position by the
chain provided.
For safety, and economy, ensure that the regulator is fully closed, (turned counter-clockwise) when not welding
and when fitting or removing the gas cylinder.
•
Turn the regulator adjustment knob counter-clock wise to ensure the valve is fully closed.
•
Screw the gas regulator fully down on the gas bottle valve, and fully tighten.
•
Connect the gas hose to the regulator securing with clip/nut provided.
•
Open the cylinder valve, then set the gas flow to approx. 8l/min. on the regulator.
•
Operate the torch trigger to ensure that the gas is flowing through the torch.
5.4.6 MANUAL MIG WELDING (REFER TO FIGURE 1)
•
Select Manual MIG Welding function thru the Selector Key (1) on
the front panel. The Led corresponding to manual MIG Welding
will stay lit.
•
Keep the selector Key (2) pressed to load wire and make gas test.
The wire loading will start at a preset speed after 2 seconds after
the selector key is pressed.
GAS MIG WELDING
•
Connect the earth cable to the negative socket (9) of the unit.
•
Connect the torch connection cable to the positive terminal of
Voltage Change Board inside the unit side.
NO GAS MIG WELDING
•
Connect the earth cable to the positive socket (10) of the unit.
•
Connect the working cable to the negative terminal of Voltage
Change Board inside the unit side.
•
Select type of gas (3), wire speed (4) and welding voltage (5).
5.4.7 SYNERGIC MIG WELDING (REFER TO FIGURE 1)
•
Select Synergic MIG Welding function thru the Selector Key (1) on the front panel. The Led corre-
sponding to synergic MIG Welding will stay lit.
•
Keep the selector Key (2) pressed to load wire and make gas test. The wire loading will start at a
preset speed after 2 seconds after the selctor key is pressed.
•
Select wire diameter (2), tipy of gas (3).
•
Wire speed automatically sets, however the operator has the chance to fine set the wire speed thru
the potentiometer (4) on the front panel, the allowed balancing is ±40%.
•
Set welding power thru the potentiometer (5). Turning it clockwise the welding voltage is increased
and as consequence the material thickness that can be welded is higher.
•
NOTE: the minimum and maximum thicknesses that can be selected depend on the wire diameter
and gas type selection. Refer to the example table:
