Translation of the original instructions
SEMI-AUTOMATIC WELDING FOR STEEL/STAINLESS STEEL (MAG MODE) (FIG II)
These welding can weld 0.6/0.8 and 1.0 mm steel and stainless steel wires (fig III-A). The device is capable of working
with Ø 0.8 mm steel wire (contact tube Ø 0.8, roller Ø 0.6/0.8 and Ø 0.8/1.0 mm). If you need to use Ø 0.6mm wire,
you will have to change the contact tube, and ensure that the reversible rollers in the wire feeder are posititioned cor-
rectly (so that the writing that states "0.6mm" is visible when in place). For Steel or Stainless Steel, you will need to use
specific gas - Argon + CO2 (Ar + CO2). The proportion of CO2 will vary depending on usage. The gas flow in steel is
between 8 and 12L / min depending on the environment and experience of the welder. For the specific requirements,
seek advice from your gas distributor.
SEMI-AUTOMATIC BRAZING WELDING FOR HIGH-TENSILE STRENGTH STEELS
These welding are recommended by car manufacturers to braze-weld high-tensile strength plates with a cuprosilicium
CusI3 wire or cuproaluminium CuAl8 wire (Ø 0.8 mm and Ø 1 mm). The welder must use a neutral gas: pure argon (Ar).
For specific gas requirements, seek advice from your gas distributor. The gas flow required s between 15 and 25 L / min.
GAS CONNECTION (FIG I)
Connect the manometer (flowmeter) to the gas bottle (manometer not supplied with the product).
For use with one bottle of gas.
To avoid any gas leaks, always use the collars supplied with the product.
PROCESS OF REELS AND TORCHES ASSEMBLY (FIG III)
- Open the device trapdoor.
- Place the reel on the driving pin (fig III-2) of the reel support.
- Adjust the reel brake (fig III-3) to avoid the reel inertia tangling the wire when welding stops. In general, do not tigh-
ten too much!
- The electrical roller (fig III-4) is a double groove roller (0,6/ 0,8 and 0,8/1). The indication on the visible side of the
roller is the diameter in use. For a 0,8 wire, use the 0,8 groove.
- For the first use:
- Release the fixing screw of the wire guide.
To set the adjusting knob of the pressing rollers (fig III-5), proceed as follow: loosen the knob fully, start the motor by
pressing the torch trigger, tighten the adjustment knob whilst pressing the trigger. Bend the wire where it comes out
of the nozzle and hold it in place to stop its progress. The setting is correct when the guide roller slides over the wire
even when it is blocked at the end of the torch. A common adjustment is the rollers command (fig III-5) on the scale
3 for steel.

CONTROL KEYBOARD (FIG IV)
1-welding mode choice :
- Normal (2T) : standard two-stage welding
- Delay: intermittent welding modes for an optimised
operating procedure.
- Spot:spotwelding with ajustable spot diameter
2- Wire speed settings : wire speed fitting potentiometer.
The speed varies from 1 to 15L/minute.
3- Spot/delay potentiometer fitting
4- Manual mode : In manual mode, the wire speed is de-
terminated by the user by adjusting the potentiometer (2).

5- Synergic mode: position the potentiometer (2) in the
middle of the «optimal synergic» zone. In this mode, the
device determines the optimal wire speed according to 3
parameters :
- Voltage
- Wire diameter (5a)
- The power mode (5b).
It's possible to adjust the wire speed +/-.
In position Normal(2T), 2 modes are proposed to ease
the settings of the device: Manual or Synergic.
6- thermal protection light : informs when a short break
is necessary following intensive use.
