Make sure that the cooling unit is turned off before disconnecting the inlet and outlet hoses for torch liquid.
The coolant is harmful and irritates the eyes, the mucous membranes and the skin. Hot liquid may cause burns.
REEL INSTALLATION AND WIRE LOADING (III)
• Remove the nozzle (III-F) and the contact tube (III-E) from the torch.
• Open the machine door.
III-A :
• Position the reel on its support:
- Take into account the drive pin of the reel holder To fit a 200 mm (10kg) wire reel, tighten the wire reel support to the maximum.
• Adjust the brake (III-2) to prevent the wire from tangling when the weld stops. Overall, do not excessively tighten the brake, which would cause
the motor to overheat.
III-B :
• Fit the motor drive rolls suitable for the application. The original drive rolls supplied are double steel groove rollers (1.0 and 1.2).
- Check the marking on the drive roll to ensure that they are suitable for the diameter of the wire
and the material of the wire (for a Ø 1.2 wire, use the Ø 1.2 groove).
- Use drive rolls with V-groove for steel and other hard wires.
- Use drive rolls with U-slots for aluminium and other soft alloy wires.
III-C :
To change the thread, proceed as follows:
• Loosen the knobs (III-4) to the maximum and lower it, insert the wire, then close the motorized reel and tighten the knobs as indicated.
• Operate the motor by pressing the torch trigger or the shuttle (I-7) in the wire change position.
• Remove the wire from the torch by about 5 cm, then place the contact tube adapted to the wire used (III-E) and the nozzle (III-F) at the end of
the torch.
Remarks :
• A torch liner that is too narrow may cause wire feeding problems as well as motor overheating.
• The torch connector must also be tight to prevent overheating.
• Check that neither the MIG/MAG wire nor the wire reel are in contact with the machine's mechanical parts, otherwise there si a
danger of short-circuit.
SEMI-AUTOMATIC STEEL / STAINLESS STEEL WELDING (MAG MODE)
PULSEMIG can weld steel wire from Ø 0.6 to 1.2 mm and stainless steel wire from Ø 0.8 to 1.2 mm (II-A).
The device is supplied as standard to operate with Ø 1.0 mm steel wire (Ø 1.0/1.2 roller). The contact tube, the roller groove, the torch sheath are
designed for this application. When welding wire with a diameter of 0.6, use a torch with a length of no more than 3 m. The contact tube (III-E)
and the drive roll (III-B) in the motor should be replaced by equivalent parts with a 0.6 groove (ref. 061859). In this case, position it in such a way
that the inscription 0.6 (III-B) is facing you.
Welding steel requires a specific gas (Ar+CO2). The proportion of CO2 may vary depending on the gas used. For stainless steel, use a mixture with
2% CO2. When welding with pure CO2, it is necessary to connect a gas preheating device to the gas cylinder. For specific gas requirements, please
enquire with your gas distributor. The gas flow rate for steel is between 8 and 15 litres / minute depending on the environment.
SEMI-AUTOMATIC ALUMINIUM WELDING (MIG MODE)
PULSEMIG can weld aluminium wire from Ø 0.8 to 1.2 mm (II-B).
Aluminium use requires a specific pure argon gas (Ar). For specific gas requirements, please enquire with your gas distributor. The aluminium gas
flow rate is between 15 and 25 l/min depending on the environment and the welder's experience.
The differences between using the unit on steel or aluminum are:
- Use specific drive rolls for aluminium welding.
- Apply minimum pressure on the pressure rollers of the motor-driven reel to avoid crushing the wire.
- Use the capillary tube (designed to guide the wire between the drive rolls in the motor and the EURO connector) only for steel/stainless steel
welding (II-B).
- Use a torch designed for aluminium. This aluminium torch is fitted with a teflon torch liner in order to reduce frictions. DO NOT cut the liner at the
edge of the fitting! This liner guides the wire from the drive rolls.
- Contact tube: use a SPECIAL aluminium contact tube corresponding to the diameter of the wire.
When using red or blue liner (aluminium welding), it is recommended to use the part no.91151 (II-C). This
stainless steel liner guide improves the centering of the sheath and facilitates the wire feed.
