RESIDUAL RISKS
-
OVERTURNING: position the welding machine on a horizontal surface that
is able to support the weight: otherwise (e.g. inclined or uneven floors etc.)
there is danger of overturning.
-
IMPROPER USE: it is hazardous to use the welding machine for any work
other than that for which it was designed (e.g. de-icing mains water pipes).
-
MOVING THE WELDING MACHINE: Always secure the gas bottle, taking
suitable precautions so that it cannot fall accidentally.
The safety guards and moving parts of the covering of the welding machine and
of the wire feeder should be in their proper positions before connecting the
welding machine to the power supply.
WARNING! Any manual operation carried out on the moving parts of the wire
feeder, for example:
- Replacing rollers and/or the wire guide;
- Inserting wire in the rollers;
- Loading the wire reel;
- Cleaning the rollers, the gears and the area underneath them
- Lubricating the gears
SHOULD BE CARRIED OUT WITH THE WELDING MACHINE SWITCHED OFF
AND DISCONNECTED FROMTHE POWER SUPPLY OUTLET.
- Never lift the welding machine

5.2 HOWTO LIFTTHEWELDING MACHINE
Microprocessor controlled, fan-cool ed, three-phase welding machine on wheels for
MIG-MAG welding and brazing. Especially suitable for use in light carpentry and body
shop, for welding galvanised sheet, high stress (high yields) materials, stainless steel
and aluminium. It allows automatic setting of wire speed according to the features of
the material being welded, the shielding gas and the wire diameter. Use with SPOOL
GUN torch. Complete with MIG-MAG welding accessories.
This welding machine is designed for use with the SPOOL GUN torch, used for
welding aluminium and steel when the power source and piece to be welded are far
apart.
- Power supply voltage monitor.
- Spot, 2/4-stroke operation.
- Automatic torch recognition.
- Regulation of wire slope up, post-gas time, wire burn-back time.
- Ready for use with SPOOL GUN torch.
- Thermostatic safeguards.
- torch.
- return cable complete with earth clamp.
- pressure reducing valve.
- connecting cable kit (only for version with separate wire feeder).
- spool gun.
- aluminium welding kit,
- stainless steel welding kit,
The most important data regarding use and performance of the welding machine are
summarised on the rating plate and have the following meaning:
EUROPEAN standard of reference, for safety and construction of arc welding
machines.
Symbol for internal structure of the welding machine.
Symbol for welding procedure provided.
Symbol
: indicates that welding operations may be carried out in environments
with heightened risk of electric shock (e.g. very close to large metallic volumes).
Symbol for power supply line:
1~: single phase alternating voltage
3~: 3-phase alternating voltage
Protection rating of the covering.
Technical specifications for power supply line:
Alternating voltage and power supply frequency of welding machine (allowed
limit ±10%):
Maximum current absorbed by the line.
: effective current supplied
Performance of the welding circuit:
maximum no-load voltage (open welding circuit).
current and corresponding normalised voltage that the welding machine
can supply during welding
Duty cycle: indicates the time for which the welding machine can supply the
corresponding current (same column). It is expressed as %, based on a 10 min.
cycle (e.g. 60% = 6 minutes working, 4 minutes pause, and so on)
If the usage factors (on the plate, referring to a 40°C environment) are exceeded,
the thermal safeguard will trigger (the welding machine will remain in standby
until its temperature returns within the allowed limits).
shows the range of adjustment for the welding current (minimum
maximum) at the corresponding arc voltage.
Manufacturer's serial number for welding machine identification (indispensable for
technical assistance, requesting spare parts, discovering product origin).
: Size of delayed action fuses to be used to protect the power line
Symbols referring to safety regulations, whose meaning is given in chapter 1
“General safety considerations for arc welding”.
Note: The data plate shown above is an example to give the meaning of the symbols
and numbers; the exact values of technical data for the welding machine in your
possession must be checked directly on the data plate of the welding machine itself.
- intermittent buzzer;
Knob for adjusting wire feed rate and for setting accessory welding
parameters (in programming mode).
LED on: indicates that wire feed is at recommended rate (pre-set default
value).
Button for selecting 2/4-stroke, spot welding.
(steel, stainless steel, aluminium,
coppersilicon or copper-aluminium alloys for MIG brazing).
