Introduction And General Description; Standard Accessories; Optional Accessories; Technical Data - Telwin MIG Manual De Instrucciones

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 FROM THE POWER SUPPLY OUTLET .
- Never lift the welding machine

2. INTRODUCTION AND GENERAL DESCRIPTION

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.
2.1 Main features:
- 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.

2.2 STANDARD ACCESSORIES:

- torch.
- return cable complete with earth clamp.
- pressure reducing valve.

2.3 OPTIONAL ACCESSORIES

- spool gun.

3. TECHNICAL DATA

3.1 DAT A PLATE
The most important data regarding use and performance of the welding machine are
summarised on the rating plate and have the following meaning:
1- EUROPEAN standard of reference, for safety and construction of arc welding
machines.
2- Symbol for internal structure of the welding machine.
3- Symbol for welding procedure provided.
4- Symbol S: indicates that welding operations may be carried out in environments
with heightened risk of electric shock (e.g. very close to large metallic volumes).
5- Symbol for power supply line:
1~: single phase alternating voltage
3~: 3-phase alternating voltage
6- Protection rating of the covering.
7- Technical specifications for power supply line:
- U : Alternating voltage and power supply frequency of welding machine (allowed
1
limit ±10%):
- I : Maximum current absorbed by the line.
1 max
- I : : effective current supplied
1eff
8- Performance of the welding circuit:
- U : maximum no-load voltage (open welding circuit).
0
- I /U : current and corresponding normalised voltage that the welding machine
2 2
can supply during welding
- X : 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).
- A/V-A/V: shows the range of adjustment for the welding current (minimum
maximum) at the corresponding arc voltage.
9- Manufacturer's serial number for welding machine identification (indispensable for
technical assistance, requesting spare parts, discovering product origin).
10- : Size of delayed action fuses to be used to protect the power line
11- 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.

4.1 CONTROL, ADJUSTMENT AND CONNECTION DEVICES

4.2 CONTROL PANEL

LED showing thermostatic protection. Indicates welding cutout due to
overheating.
LED's showing power supply voltage.
- low main supply voltage (welder underpowered)
- normal main supply voltage (welder powered correctly)
- high main supply voltage (welder overpowered)

WARNING:

Under faulty power supply conditions, the following
conditions will occur:
- over- or under- voltage LED will light up;
- intermittent buzzer;
- the display will show ALL UPP or ALL LOW.
We recommend switching the welder off to prevent it being damaged.
A
: LED on: the display shows the welding current.
Intermittent LED: Wire feed rate up slope programming mode
m/min
LED on: the display shows wire feed rate.
Intermittent LED: Wire burn back time programming mode
sec
LED on: the display shows spot welding time
Intermittent LED: Post-gas time programming mode
Dual function button: if pressed and released it will show the welding
current, wire feed rate and spot welding time (only if spot welding
operation is selected!)
If the button is pressed for at least 3 seconds, this gives access to
welding parameter programming mode.
To exit programming mode press the button again for at least 3 seconds.
Knob for adjusting wire feed rate and for setting accessory welding
parameters (in programming mode).
DEFAULT LED on: indicates that wire feed is at recommended rate (pre-set default
value).
Button for selecting 2/4-stroke, spot welding.
Wire diameter selection button
Welding gas selection button
Welding material selection button (steel, stainless steel, aluminium,
coppersilicon or copper-aluminium alloys for MIG brazing).

5. INSTALLATION

__________________________________________________________________
WARNING!
CARRY OUT ALL INSTALLATION OPERATIONS AND ELECTRICAL
CONNECTIONS WITH THE WELDING MACHINE COMPLETEL Y SWITCHED OFF
AND DISCONNECTED FROM THE POWER SUPPLY OUTLET .
THE ELECTRICAL CONNECTIONS MUST BE MADE ONLY AND EXCLUSIVEL Y
BY AUTHORISED OR QUALIFIED PERSONNEL.
__________________________________________________________________

5.1 PREPARATION

Unpack the welding machine, assemble the separate parts contained in the package.
Assembling the return cable-clamp

5.2 HOW TO LIFT THE WELDING MACHINE

None of the welding machines described in this manual is equipped with a lifting
device.

5.3 SITE

Locate the welding machine in an area where openings for cooling air are not
obstructed (forced circulation with fan), leave at least 250mm free space around the
welding machine; check that conductive dusts, corrosive vapours, humidity etc., will
not enter welding machine.
__________________________________________________________________
WARNING: Position the welding machine on a flat surface with sufficient
carrying capacity for the weight of the welding machine, to prevent tipping or
hazardous movement.
