What is Pulse MIG & how does it work
Spool & Wire Feed Set Up for 250MST & 220MP
What is an Inverter Welder?
What is Duty Cycle?
What is the Maximum material thickness the 220MP can MIG weld?
Firstly it is important to understand that;
a. The 'maximum weldable thickness' will be less in pulse modes than it will in non-pulse modes. This is becuase pulse is more complex, with multiple current levels, and typically requires more power than conventional MIG to weld the same material thickness.
b. The same applies to single-pulse and double-pulse: Single-pulse will typically allow welding of slightly heavier materials compared to double-pulse.
c. Maximum thickness capacity will vary depending on the application. One important factor is 'heat sink'. Larger workpieces / components absorb more heat (especially aluminium which is a very good thermal conductor), which means more/higher current is required, which then reduces the maximum weldable thickness.
In NON-Pulse manual mode, the 220MP will weld up to approx. 10mm mild steel or 8mm aluminium.
In Pulse modes, the maximum material thickness is around 5mm. If welding aluminium, Single-Pulse mode will weld up to 6mm, Double-Pulse up to 5mm.
For the above reasons, successful Pulse MIG welding of materials over 5-6mm typically requires 3-phase machines.
What is the Minimum material thickness the 220MP can MIG weld?
Again, this will vary depending on the application. Following is a general guide;
Aluminium: While the 220MP pulse & non-pulse programs have a minimum thickness setting of 0.8mm, welding Aluminium less than 2mm with pulse (or less than 3mm with conventional MIG) can be very challenging. Fortunately the vast majority of aluminium applications involve material thickness of 2-3mm or more.
Stainless-Steel: Pulse mode is highly recommended for thin stainless material, to minimise distortion. Minimum thickness setting in pulse mode is 0.8mm.
Bronze: Minimum thickness setting in pulse mode is 0.8mm.
Mild Steel: The ATC (Advanced Thermal Control) feature allows excellent results when welding thin steel in Synergic Non-Pulse mode. Minimum thickness setting in Synergic mode is 0.6mm, however this setting can also be used for welding down to 0.5mm material.
Can you Pulse MIG weld mild steel with the 220MP?
The 220MP can be used to weld mild-steel wires in non-pulse (Manual, Synergic or Root MIG) modes, however not in pulse modes. There are several reasons for this;
Mild-steel does not present the same "thermal challenges" as other metals like aluminium or stainless, and therefore pulse does not neccessarily offer the same advantages. For this reason, conventional MIG (rather than pulse MIG) is typically still the best process for welding mild steel, especially in the material thickness range that is achievable with single-phase machines.
Pulse MIG can offer some productivity advantages for welding heavy steel, however this requires a high "peak" current which is available only from three-phase pulse machines.
If welding thin mild steel material, the 220MP will offer exceptional thermal control in the non-pulse programs, due to the ATC (Advance Thermal Control) feature. The Root MIG program also allows "gap-fill" welding of mild steel (including thin material) with results that would normally only be achievable with TIG.
Why is the drive system 2-roll & not 4-roll ?
Reliable and consistant wire feeding is certainly essential for successful pulse MIG welding. To achieve this, traditional machines with "100% mechanical" drive controls rely on 4-roll drive systems. The 220MP, however, uses a Swiss-made intelligent 2-roll wire drive system with electronic Tacheometric Control. This means that the machine software monitors wire feed speed against weld parameters, at intervals of more than 100 times per second, and self-calibrates wire feed speed, for exceptionally smooth and consistant wire feeding.
The result is wire feed that is not only as reliable as any 4-roll system, but is also live-syncronised with feedback from the arc parameters, to automatically compensate for any changes in the arc conditions. This helps to makes the 220MP simple and user-friendly to operate, so the operator can "set and forget" rather than spend time continually having to tweak machine settings.
Also, being a portable single-phase machine, weight is obviously an important factor and utlilising an intelligent 2-roll system (rather than a heavier 4-roll system) contributes to the 220MP being one the most compact and lightweight machines in it's class (22kg).
Why is the MIG torch supplied with the 220MP 3m long? Can the 220MP be used with a 4m torch?
The remote-control MIG torch supplied with the 220MP is 3m long. This is the optimum length for successful & consistant wire feeding of aluminium, which is especially critical in pulse applications.
If you need a torch longer than 3m for aluminium welding, we recommend the Platinum PP365 8m Push-Pull MIG Torch
If welding with steel or stainless-steel wires, a standard 4m torch can be used if required. For this we recommend the Promax BZL 25 torch.
Does the 220MP have reverse-polarity / gasless wire capability ?
For good reason, the 220MP does not have gasless wire (reverse MIG polarity) functionality.
For successful and reliable pulse welding, it is absolutely essential that there are no loose connections anywhere along the "current path" - including all cables/leads and connections. Becuase the 220MP has been designed with Pulse MIG function as the #1 priority, the option of reverse polarity - for welding with gasless wire - has been deliberately excluded on this machine; A) because pulse is not applicable for gasless wire, and B) this minimises the number of connections, to prevent any issues caused due to incorrect polarity, loose / worn connections, etc.
**Standard warranty 2 years, with 2 years extension if registered online.

A fantastic welder, some of the best welds I've ever done, and the root gap function is phenomenal for panel welding. It's very easy to use and operate. This is my first time using a pulse MIG, and I have to say I'm extremely impressed. It was a breeze to set up. The welds that followed were a dramatic improvement, and I tried vert up, down, fillet, butt, lap, and overhead positions with great success. Even with minimal setting up, the machine performs beautifully. Welds look good, had great penetration, and passed bend tests. I'm very keen to hone the settings to allow a softer looking weld, but other than that, this machine is incredibly capable. I believe it will completely replace my AC/DC pulse TIG's role in my workshop.

A REVIEW FROM OUR TECHNICAL TEAM:
What are the stand-out features of this machine? Very easy-to-use, intuitive controls that are easy to follow for beginner or experienced pulse MIG welders alike.
Who would benefit most from this machine? Operators needing a single-phase machine that can deliver high-quality welding on a range of materials, especially aluminium.
Any not-so-obvious features we should know about? Remote amp controls on handpiece, intelligent wire drive system, USB interface.
Limitations to be aware of? Not suitable for welding gasless wire (there's very good reasons for this, see FAQs section under "More Info" tab).
Other comments? Compact, lighter than many other machines in it's class, so very portable for a pulse machine. Arguably the most affordable European-made 250A multi-function Pulse MIG readily available in Australia, with 4-year warranty.
