Multiprocess welding systems

Why multiprocess welding systems?

Multiprocess welding systems are systems that can carry out more than one welding process to a high standard. Most welding systems are equipped to perform more than one of the three processes (MIG, STICK OR TIG), but this does not automatically make them multiprocess systems. For example, the technical capabilities of a MIG system also allow for the integration of the SMAW welding process (reduced workload), and SMAW welding can also be easily combined with the TIG welding process.

However, this usually leads to reduced output during one of the processes, affecting arc stability and welding performance. Thus, the devices do not demonstrate “true” multiprocess capability. The term “multiprocess” can only be applied to welding systems that are able to perform all three processes to virtually the same standard. Only then does the user see real added value compared with a welding system that specializes in just one process.

Questions on multiprocess series?

Devices in the multiprocess series can perform all three MIG, TIG and SMAW welding processes to a high standard. Whether on a construction site or in the workshop, the welder always has flexibility and is equipped for a range of applications.

Multiprocess vs standard welding system

Welding systems are predominantly divided into process capability, i.e. MIG, TIG or SMAW. Devices that specialize in only one of these processes boast various functions so that the user can benefit from maximum welding performance and user-friendliness. For example, current TIG welding systems feature a module for high-frequency ignition. For SMAW welding systems, ignition properties and high arc stability are the main focus. MIG systems are distinguished by numerous setting options, which allow the arc and weld seam to be adapted according to conditions. These functions only make the devices special devices for the respective process. In contrast, for multiprocess systems, flexibility of the tool is the primary concern: whatever the welding task, the user is always well equipped. What’s more, the devices are small, versatile and considerably more portable than standard devices. However, in order to combine all these properties in one device, some compromises have to be made: by way of example, additional functions such as high frequency ignition result in a heavier device and reduced mobility.

Solution

What makes a good multiprocess welding system?

In principle, the system should be able to perform all three processes without any specific drawbacks. To do so, the device must meet certain criteria:

Increased open circuit voltage for good SMAW ignition properties
Second gas solenoid valve for TIG mode
TIG socket for direct welding torch connection with internal gas supply
TIG pulse welding – not strictly a must, but forms part of a TIG welding system
TMC (TIG Multi Connector) for using a TIG U/D welding torch- All three processes on one control panel
The control system must be able to regulate all three processes (control of gas solenoid valve, TMC for U/D TIG welding torch, motor control for MIG, FSC for U/D MIG welding torch)
Polarity reverser for using self-shielding flux core wires that must be welded on the negative pole

Advantages of multiprocess systems

Flexibility during the processes
Many materials and material thicknesses covered
Lower investment costs
Less training needed
Welding system can be adapted to the application

Disadvantages of multiprocess systems

Some drawbacks when carrying out processes
Device is larger in size than devices with max. two processes
Operation becomes more complex with each additional process

The different welding processes in detail

The MIG welding process usually forms the basis for a multiprocess system. MIG systems are somewhat larger in size, as the other processes are integrated in the original device. The processes are explained in detail:
