SEMI-AUTOMATIC BRAZING FOR HIGH-TENSILE STRENGTH STEELS
The Trimig 200-4S can braze-weld high-tensile strength plates with Cuprosilicium CusI3 wire or Cuproaluminium CuAl8
wire (Ø 0.8 mm and Ø 1 mm). The welder must use a neutral gas: pure argon (Ar). For specific gas requirements seek
advice from your gas distributor. The required gas flow is between 15 and 25L / min.
REEL AND TORCH ASSEMBLY (FIG IV)
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 sup -
port.
• Adjust the reel brake (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:
- Release the fixing screw of the wire guide (5).
- Place the rollers, and tighten the screws (9).
- 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) : 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.

GAS COUPLING
Fit the regulator/flowmeter to the gas bottle and then fit the gas pipe to the connector. To avoid gas leaks use the collars
provided in the accessories box. Ensure proper maintenance of the gas cylinder in accordance with the attachment of
the chain cf. IV-1. Assurer le bon maintient de la bouteille de gaz en respectant la fixation de la chaine cf. IV-1

Wire speed regulator
The speed varies from 1 to 15 m/minute.
SPOT/DELAY setting potentiometer (5)
Manual Mode (1)
In manual mode, the wire speed is determined by the
user by adjusting the potentiometer (4).
Synergic Mode (3)
Position the potentiometer (4) in the middle of the «
