SEMI-AUTOMATIC FOR STEEL/STAINLESS STEEL (MAG MODE) (FIG III)
The Trimig 200-4S can weld 0.6/0.8/1.0 steel/stainless wire. (FIG-III-A) The product is supplied ready to weld for Ø1.0 mm steel (contact tip Ø 1.0,
rollers Ø 0.8/1.0). If you need to use wire of an inferior diameter, you will have to change the contact tube. The roller of the moto wire feeder is a
reversible roller. Ensure that the reversible rollers in the wire feeder are posititioned correctly - so that the writing that states the desired diameter
is visible when in place (on the side of the roller). The Trimig 250-4S DV 230-400V can weld Ø0.8/1.0/1.2 steel/stainless steel wire. The product is
supplied ready to weld for Ø1.0 mm steel (rollers Ø 0.8/1.0). The Trimig 300-4S can weld Ø0.8/1 and 1.2 steel and stainless steel wire. The product
is supplied ready to weld with Ø1mm steel wire (roller Ø 1/1.2). For Steel or Stainless Steel, you will need to use a specific welding 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 Trimig 200-4S can weld 0.8/1.0 aluminium wire. (FIG-III-B) The Trimig 250 and 300 can weld Ø1.0/1.2 aluminium wire. (FIG-III-B) To weld alu-
minium, neutral 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 depending on the environment and experience of the welder. Below, find the differences between steel welding and
aluminium welding:
• The rollers pressure on the wire: put a minimum pressure in order not to flatten the wire.
• Capillary tube : remove the capillary tube before connecting the aluminium torch with a teflon torch liner.
• Torch : use an aluminium torch. This torch has a teflon torch liner in order to reduce frictions.
• DO NOT cut the sheath This torch liner guide the wire from the rollers. (FIG-III-B)
• Contact tip : use a SPECIAL aluminium contact tip which matches the wire diameter.
SEMI-AUTOMATIC BRAZING WELDING FOR HIGH-TENSILE STRENGTH STEELS
The Trimig 200-4S can braze-weld high-tensile strength plates with a cuproaluminium CuAl8 wire (Ø 0.8 mm and Ø 1 mm). The welder must use a
neutral gas: pure argon (Ar). For the specific requirements, seek advice from your gas distributor. The gas flow required s between 15 and 25 L / min.
« NO GAS » WELDING
The Trimig 300-4S can weld « No Gas » by performing a polairty reversal (FIG-VIII - maximum tightening torque of 5 Nm).
Welding flux cored wire with a standard nozzle can cause overheating and damage the torch. Prefer a special « No Gas » nozzle (réf. 041868), or
remove the standard nozzle (FIG-VII).
PROCESS OF REELS AND TORCHES ASSEMBLY (FIG IV / 46)
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. In general, do not tighten too much! 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)
- Put the rollers, then tighten the screw retainer (9).
- put the wire guide in place (7) as close as possible to the roller with no contact, then tighten the fixing screw.
• To set the adjusting knob of the pressing rollers (6), proceed as follow: Loosen the knob fully, start the motor by pressing the torch trigger, tighten
the adjustment knob whilst pressing the trigger.
movement. 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 (6) on the scale 3-4 for steel and 2-3 for aluminium.

GAS CONNECTION
Connect the manometer (flowmeter) to the gas bottle if needed, then connect the gos hose to the gas connector. To prevent gas leaks, use the hose
clips supplied in the accessories box. Make sure the gas bottle hold in place respecting chain fastening cf. FIG-IV-1
Maximum gas pressure 0.5MPA (5 bars).
