This Inverter welder has programs for Steel, Brass, Stainless Steel, Aluminium, TIG and Electrode welding. However it is incredibly easy to use and with very little training, your operators will be getting first class results in no time. Approved for use on Mercedes Benz, Peugeot/Citroen, Ford and others, it also has programs for the CuSi3 and CuAl8 brazing wires.

Maybe there have been many times where you have been MIG welding on a car and you have needed to change wires to do either MIG Brazing or Aluminium. The time spent changing bottles and spools is wasted and probably very inconvenient too.

The new InvertaPuls IP6/2 can be set to weld any combination of Steel, Brazing or Aluminium wire. Once the wire is fitted and the bottles turned on, the use of the welder is simple.

By pressing the trigger on one torch it recognises the job it has to work on. The pre-set parameters means the Amps, Volts and wire speed are automatically set and the rest is down to the operator. It is even possible to store the individual programs for the different jobs. This is invaluable for doing repeat work.

General Information MIG-MAG welding units
MIG/MAG welding is a system where the welding wire is the carrier of the electric arc. Surrounding the contact tip is the gas nozzle which emits the protective gas that protects the welding bead from oxygen contamination.

MIG Metal Inert Gas welding
In this technology inert gas such as argon, helium and mixtures of these components are used. By being inert, the gases do not react with other materials. Mainly used for welding Aluminium, copper, titanium and other non-ferrous metals.

MAG Metal Active Gas welding
For MAG welding, gases like CO2, Argon and mixtures of these gases are used. For special purposes oxygen can also be added. Mainly used for mild steel and stainless steel.

MIG Brazing
Where spot-welding is inappropriate, the new Advanced High Strength Steels (AHSS) should be welded with a MIG brazing machine using either CuSi3 or CuAl9 wire. Other wires may be specified so your welding machine should be able to cope with these as well. Only 100% Argon should also be used as the protective gas.

MIG welding wire melts at about 1500°C, which is too hot for the new AHSS steels. Overheating changes the molecular structure of the steel, making it brittle and susceptible to rusting. MIG Brazing wire on the other hand melts at around 900°C and flows between the gap, leaving a repair that is formable and yet stills retains the correct tensile strength.

When the repair is completed, the brazing wire should have flowed between the gap and there should be no burning or powdering of the protective coating on either surface.

What choice?
The choice of welding equipment is therefore very important indeed. It is not advisable to try and convert equipment designed for steel welding by just changing over the wire and gas.

Because the power setting between each of the stepped adjustments is fixed, it is unlikely that the correct amps or volts will be selected to give suitable results. In essence, the welding power would either be too strong and in which case it will burn the coating, or not strong enough and in this case the weld will be too weak.
