SEMI-AUTOMATIC WELDING FOR STEEL / STAINLESS STEEL (MAG MODE)
These machines can weld Steel and Stainless Steel wires of 0.6/0.8 or 1.0mm (fig III - A)
The machine is delivered equipped to operate with Ø0.8mm Steel/Stainless steel wire: contact tip, roller throat and
sleeve of the torch are suitable for this application.
Should you wish to use 0.6mm wire, you will need to change the contact tip. The wire reel is reversible (0.6 / 0.8 mm)
and will need to be inserted into the machine so that the figure 0.6 is visible. For welding with Ø 1.0 mm wire, you will
need to use a specific roller and contact tip.
For welding with Steel or Stainless Steel we recommend to use Argon + CO2 (Ar+CO2). The proportion of CO2 required
will vary depending on the use. For specific gas requirements, please contact your gas distributor. The gas flow in steel
is between 12 and 18 Litres/minute depending on the environment and experience of the welder.
SEMI-AUTOMATIC WELDING FOR ALUMINIUM (MIG MODE)
This device can also weld Ø0.8 mm aluminium wire (fig III-B)
Welding on aluminium needs a specific gas: Argon (Ar). When welding aluminium, the gas flow-rate should be tuned
between 15 and 25l/min according to the environment and the welder experience.
Here are the differences between use with steel and use with aluminium :
- Rollers: use specific rollers for aluminium welding.
- Pressure of motor pressure rolls on the wire: put a minimum of pressure in order not to squash the wire.
- Use the capillary tube (designed to guide the wire between the drive rolls and the euro connector) only when welding
in MIG/MAG.
- Torch: use a special aluminium torch which is equipped with a Teflon (not included) sheathing in order to reduce fric-
tion. DO NOT cut the sheathing close to the joint! The sheathing is needed to guide the wire from the rolls.
- Contact tube: use a Ø0.8 mm special aluminium contact tube (ref.: 041509 – not included).
PROCESS OF REELS AND TORCHES ASSEMBLY (FIGURE V, PAGE 3)
• Remove the Nozzle from the torch by turning clockwise and then remove the contact tip, leaving the support and the
spring on the torch.
This product takes Ø 200/300 mm wire reel (compatible coil with plastic carcass and ecological wire carcass)
Open the door of the machine.
• Place the reel on the driving pin (3) of the reel support. To install a 200mm wire reel, fit an adaptor on the support
(ref. 042889).
- Adjust the reel brake (4) to avoid the reel inertia tangling the wire when welding stops. Do not overtighten! Tighten
the fixing screw (2).
• The electrical rollers (7) are double groove rollers (Ø 0,8/ Ø 1 or Ø 1/ Ø 1,2). The indication on the visible side of the
roller is the diameter in use. For a Ø1 mm wire, use the Ø1 groove.
• For the first use :
- Release the fixing screw which guides the wire
- Fit the rollers, then tighten the screw retainer (8).
- Put the wire guide in place (6) as close as possible to the roller without contact, then tighten the fixing screw.
• To set the adjusting knob of the drive rollers (5), proceed as follows: Loosen the knob fully, start the motor by pres-
sing the torch trigger, tighten the adjustment knob whilst pressing the trigger. Bend the wire where it comes out of the
nozzle. Put a finger on the bended wire to avoid any movement. The setting is correct when the guide roller slides over
the wire even when it is blocked at the end of the torch.
• Adjustment of the tension on the wire (5): on the scale 3-4 for steel and 2-3 for aluminium.
GAS COUPLING
Connect a pressure regulator to the gas bottle. Connect the welding machine using the pipes, and place the two clamps
to avoid leakages.
Set the gas flow by adjusting the dial located on the pressure regulator.
NB : to help facilitate the adjustment of the gas flow, operate the drive rollers by pressing the trigger of the torch
(ensure that the drive roller is completely loose so the wire is not fed through).
