SEMI-AUTOMATIC BRAZING FOR HIGH-TENSILE STRENGTH STEELS (MIG MODE)
The MONOGYS 160-2S, 185-2S and 200-2CS are recommended by car manufacturers to braze-weld high-tensile strength
plates with a 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 gas flow required is between
15 and 25 L / min.
REEL AND TORCH ASSEMBLY
• Open the door of the machine.
• Place the reel on the drive pin  of the reel support
• Adjust the reel brake  to avoid reel movement tangling the wire when the welding stops. Be careful not to
tighten too much - the reel must rotate without straining the motor.
• The wire rollers are double-grooved  (Ø 0.6/ Ø 0.8, Ø 0.8/ Ø 1, Ø 1/ Ø 1.2). The visible diameter indicated on
the roller when fitted is the diameter currently in use. For Ø 0.8 wire, use the Ø 0.8 groove.
• Before use:
- Release the fixing screw of the wire guide 
- Place the rollers
- Then place the wire guide  as close as possible to the roller but without touching it, then tighten the fixing
screw.
• To set the adjustment knob of the drive rollers, 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 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. A common adjustment is the rollers command  on the scale 3 for
steel and 2 for aluminum.
GAS COUPLING
Screw the regulator/flowmeter onto the gas bottle
To avoid gas leaks, use the collars provided in the accessories box.
