SEMI-AUTOMATIC WELDING FOR STEEL / STAINLESS STEEL (MAG MODE)
This device can weld 0.8/1/1.2 mm steel and stainless steel wires, and occasionally 1.6mm wire. (fig.
⑮
)
The device is capable of working with Ø 1 mm steel wire (roller Ø 0.8/1.0)
If using Ø 1mm wire,
you should use a torch with a 1mm contact tip
, and ensure that the reversible rollers in
the wire feeder are posititioned correctly (so that the writing that states “1mm” 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 for 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. To weld 1.6mm wire,
use the appropriate rollers and torch.
SEMI-AUTOMATIC WELDING FOR ALUMINIUM (MIG MODE)
This device can weld 1 mm and 1.2 mm aluminium wires. (fig.
⑯
)
To weld aluminium, neutral gas “pure Argon” (AR) is required. When choosing gas, ask a gas distributor for advice.
The gas flow in aluminium should be between 15 and 25 L / min depending on the environment and experience of
the welder.
Things to note when welding with Aluminium
- Set the pressure of the rollers to a minimum so as not to crush the wire
- Remove the capillary tube before connecting the aluminium torch
- When welding aluminium use a special aluminium torch with Teflon sheath to reduce friction.
Do not cut the sheath near the connector!
It is used to guide the wire from the rollers. (See diagram
⑯
)
- Contact Tip: Use the specific Aluminium contact tip corresponding to the diameter of the wire.
REEL AND TORCH ASSEMBLY
• Open the door of the machine.
• Position the reel on to the support
③
. To place a 200mm wire reel, first install the adapter (ref. 042889)
on the support.
• Adjust the reel break
④
to avoid the reel movement tangling the wire when welding stops.
Be careful not to
tighten too much!
Then tighten the plastic screw
② firmly
.
• The wire feeder uses double groove rollers
⑧
(Ø 0.8/ Ø 1 or Ø 1/ Ø 1.2). The visible diameter on the roller when
fitted is the one currently in use. For Ø 1 mm wire, use the Ø 1 groove.
• For first use :
o
Release the fixing screw of the wire guide
⑤
o
Place the rollers, and tighten the screws
⑨
.
o
Place the wire guide
⑦
as close as possible to the roller but without touching it, then tighten the fixing
screw.
• To select the adjustment of the drive rollers
⑥
, proceed as follows : loosen the knob fully, Start the motor by
pressing the trigger of the torch, tighten the knob whilst pressing the trigger until the wire starts to move.
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.
Common adjustment of knob
⑥
: scale 3-4 for steel, and scale 2-3 for aluminium.
