GYS TRIMIG 200-4S Manuel D'utilisation page 7

DESCRIPTION
Thank you for choosing this product; please read this instruction manual carefully before installing and using the product
and keep in a safe place for future reference.
The Trimig are semi-automatic welding units; they are ventilated for semi-automatic welding (MIG or MAG) and are
capable of welding steel, stainless steel and aluminium. Adjustment is quick and easy with their «synergic wire speed»
function. They work on a 400V three-phase power supply, and /or 230V three-phase for the DV models.
ELECTRICITY SUPPLY
The absorbed current (I1eff) is indicated on the device for use at maximum settings. Check that the power supply and
its protection (fuse and/or circuit breaker) are compatible with the current needed during use. The device must be
placed in such way that the power socket is always accessible. Do not use an extension cable which has a wire section
smaller than 4 mm². These products are supplied with a 16A or 32A plug type EEC RS/015. They should be plugged in
to a 400V (3PH) power socket WITH earth and protected by a 16A circuit breaker and 1 differential 30mA. 230V 3-phase
power supply, for Trimig 250-4S DV. WARNING: This device is pre-built in 400V three-phase. If your electrical installation
is 230V three-phase, you must modify the connection on the terminal board. This modification must be undertaken by
qualified personnel. In order to do so, please refer to the technical diagram inside the product. The plug must be pro-
tected by a 16A circuit breaker and 1 differential 30mA.

SEMI-AUTOMATIC WELDING FOR STEEL / STAINLESS STEEL (MAG MODE) (FIG III)
The Trimig 200-4S can weld 0.6/0.8/1mm steel and stainless steel wires (fig. III-A). The device is capable of working
with Ø 1.0 mm steel wire (roller Ø 0.8/1.0, contact tip of 01.0). If using lower diameter wire, you should use change the
contact tip, and ensure that the reversible rollers in the wire feeder are positioned correctly (so that required diameter
is visible when in place). The Trimig 250-4S DV 230-400V can weld 0.8/1/1.2mm steel and stainless steel wires. The
device is capable of working with Ø 1mm steel wire (roller Ø 0.8/1.0, contact tip of 1). The Trimig 300-4S can weld
0.8/1/1.2mm steel and stainless steel wires. The device is capable of working with Ø 1mm steel wire (roller Ø 1.0/1.2,
contact tip of 1). 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 10 and 20L / min depending on the environment
and experience of the welder.
SEMI-AUTOMATIC WELDING FOR ALUMINIUM (MIG MODE) (FIG III)
The Trimig 200-4S can weld 0.8mm and 1mm aluminium wires. (fig. III-B). The Trimig 250 and 300 can weld 1mm and
1.2mm aluminium wires. (fig. III-B). To weld aluminium, neutral gas "pure Argon" (AR) is required. For specific gas
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. 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 (fig III-B).
• Contact Tip: Use the specific Aluminium contact tip corresponding to the diameter of the wire.
