SEMI-AUTOMATIC FOR STEEL/STAINLESS STEEL (MAG MODE) (FIG III)
The Promig 400-4S, 400-4S DUO DV and 400 G DV can weld 0.8/1mm and 1.2mm steel and stainless steel wires. The product is
fitted to work with Ø1mm steel wire (roller Ø 1/1,2). For Steel or Stainless Steel, you will need to use a The product isfitted in stan-
dard to work with 0.8 steel wire. specific gas - Argon + CO2 (Ar + CO2). The proportion of CO2 will vary depending on usage. For
the specific requirements, seek advice from your gas distributor. The gas flow in steel is between10 and 20L / min depending on the
environment and experience of the welder.
SEMI-AUTOMATIC WELDING FOR ALUMINIUM
The Promig 400 can weld 1mm and 1.2mm aluminium wire. (FIG-III-B) To weld aluminium, inert gas "pure argon" (AR) is required.
For specific requirements, seek advice from your gas distributor. The gas flow in aluminium should be between 15 and 25 L / min de-
pending on the environment and experience of the welder. Below, see the differences between steel welding and aluminium welding:
• Rollers pressure on the wire: put only the minimum pressure in order not to flatten the wire.
• Capillary tube : remove the capillary tube before connecting an aluminium torch (with teflon torch liner).
• Torch : using an aluminium torch. This torch has a teflon torch liner to reduce friction.
• DO NOT cut the sheath near the connector ! The sheath guides the wire from the rollers. (FIG-III-B)
• Contact tip : use a SPECIAL aluminium contact tip to match the wire diameter.
REEL AND TORCH ASSEMBLY (FIG IV)
This product takes Ø 200/300 mm wire reel (ecological)
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 (8) 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 (5)
- Fit the rollers, then tighten the screw retainer (9).
- Put the wire guide in place (7) as close as possible to the roller without contact, then tighten the fixing screw.
• To set the adjusting knob of the drive rollers (6), proceed as follows: 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. 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 (6): on the scale 3-4 for steel and 2-3 for aluminium.
