FRONIUS TPS320I COMPACT GAS COOLED IN-LINE PULLMIGTORCH
FRONIUS TPS 320i COMPACT
Inverter Power Source with Built-In Wire Feeder
This package: TPS 320i Compact with Gas Cooled In-line PullMig Torch — PN: 4.075.234
The Fronius TPS 320i Compact packs the full capability of Fronius' TPS/i platform into a compact, all-in-one design with the wire feeder built straight into the power source. With its space-saving footprint and low weight, it's a genuinely portable option for construction sites and workshops, while still delivering the power and process control of a full-size TPS/i system — making it equally at home on repair and maintenance work as it is on daily production welding.
The TPS 320i Compact ships with MIG Pulse Synergic as standard, with MIG Standard Synergic, LSC and PMC available as options — so the machine can be configured to match the exact process mix a workshop needs, rather than paying for capability that won't get used.
This listing is the gas-cooled configuration with an In-line PullMig torch package — a water-cooled version is also available for higher duty-cycle and extended production applications.

Gas-Cooled & Water-Cooled Versions Available
The TPS 320i Compact is available in both gas-cooled and water-cooled configurations. This listing covers the gas-cooled version paired with an In-line PullMig torch package, suited to general fabrication and site work. A water-cooled version is also available for workshops running higher duty cycles or longer continuous welds where torch heat becomes the limiting factor — talk to the QWS team about which cooling configuration suits your application.
What's Included in This Package
This TPS 320i Compact package requires a Weld Process license and drive rollers, which are supplied as separate line items rather than built into the base unit. The complete package includes:
| Part Number | Item |

| 4.066.013 | Weld Process — Pulse Synergic |
| 44.0001.1407.4 | Drive roller FSR Ø1.2mm (4 off rollers) |
| 4.100.803.CK | Pullmig Interface Kit, TPSi Compact |
| 43.0004.0161 | Earth Cable, 50mm² x 4m, with brass clamp |
| 4.051.043 | In-line Pullmig MHP280i GAS/FSC/UD/7.85m/LED |
| 44.0350.3153 | Torch neck MTB 320i G ML/45°/L165/H75 |
| 44.0350.5226 | PM Basic Kit (BK PM Al Ø1.2 / G CuSi G/W/10m) |
Note: the TPS 320i Compact base unit requires a Weld Process license and drive rollers, which are not included and must be ordered as above to have a complete, ready-to-weld package.
Why Choose the TPS 320i Compact?
Full TPS/i capability, compact footprint. All the process control, connectivity and touchscreen interface of the larger TPS/i range, built into a wire-feeder-integrated unit small enough for site work and tight workshop spaces.
Configure it to the job. With Pulse Synergic standard and Standard Synergic, LSC and PMC available as options, the 320i Compact can be specified as a focused pulse-welding machine or built out into a broader multiprocess unit.
Built to stay current. The future-proof, upgradeable design means new software options can be added down the track without replacing the machine, and settings can be backed up via USB or monitored remotely over Ethernet.
PullMig-ready. The In-line PullMig torch package in this listing is suited to longer wire runs and improved feed consistency, particularly useful for softer wire alloys like aluminium.
Frequently Asked Questions
What welding processes does the TPS 320i Compact support? MIG Pulse Synergic and Syncropulse come standard, alongside TIG DC and manual (stick/MMA) electrode. MIG Standard Synergic is available as an option.
Is the TPS 320i Compact available water-cooled? Yes — it's available in both gas-cooled and water-cooled configurations. This listing is the gas-cooled version with an In-line PullMig torch package.
Does the TPS 320i Compact come ready to weld out of the box? The base unit (PN 4.075.234) requires a Weld Process license and drive rollers, which aren't included as standard — see the package components table above for what's needed to complete the setup.
What is Syncropulse? Syncropulse is a Fronius pulse welding function that synchronises the pulse frequency with wire feed motion, improving arc stability and weld appearance on pulse-synergic MIG welding.
What control interface does the TPS 320i Compact use? A 7" colour touchscreen with single-knob control, allowing quick access to parameters without deep menu navigation.
Can settings be backed up or the machine monitored remotely? Yes — settings can be backed up via USB, and the machine supports remote monitoring over an Ethernet connection.
