Translation of the original instructions

SEMI-AUTOMATIC FOR STEEL/STAINLESS STEEL (MAG MODE) (FIG III)

The POWERMIG 200-4 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 ref. 042360). 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 (Ø 0,6/0,8 : ref. 042353).

The POWERMIG 250-4 DV 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

ref. 042360). 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 POWERMIG 200-4 can weld 0.8/1.0 aluminium wire. (FIG-III-B). The POWERMIG 250-4 DV can weld Ø1.0/1.2 aluminium wire. (FIG-III-B) To

weld aluminium, 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.

• Rollers Ø 0,8/1,0 : ref. 042377 and rollers Ø 1,0/1,2 : ref. 040915.

SEMI-AUTOMATIC BRAZING WELDING FOR HIGH-TENSILE STRENGTH STEELS

The POWERMIG 200-4 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.

PROCESS OF REELS AND TORCHES ASSEMBLY (FIG IV / 45)

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. Bend the wire where it comes out of the nozzle. Put a finger on the bended wire to prevent 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.

• A common adjustment is the rollers command (6) on the scale 3-4 for steel and 2-3 for aluminium.
