    Stability means dependability.  

    The TIG version of the TransPocket 3500 is a digitally-controlled MMA power source system with state-of-the-art resonant intelligence its design was built and constructed to ensure stable arcs consistently. This version applies more functions than its alternative, providing much easier and more relaxed work for the user. During the generator-powered operation, stability is the name of the game with a fluctuating mains voltage of 380-460V with 3 phases. The TransPocket 3500 is ideal for those who are always on the move, as it was constructed to be the most robust and powerful small welding power source Fronius has to offer.

    • HotStart – specifically designed to make the electrode easier to ignite
    • SoftStart – developed to ensure a stable arc at the beginning of the welding process
    • TAC – created to ease the process of welding light-gauge sheets without the need for filler metal
    • TIG Comfort Stop – with this feature, the welding current is turned off automatically if a change is made to the arc length

    Fronius AC / DC TIG Welders FAQs

    Straight answers to the questions people ask most when choosing and using AC/DC TIG welders, especially for aluminium.

    What does the AC balance control do?icon-minus-redicon-plus-red

    Each AC cycle has a cleaning half and a penetration half, and the balance control changes the proportion of time spent in each. More cleaning breaks up oxide more strongly but gives shallower penetration and puts more heat into the tungsten. More penetration gives deeper, narrower welds and less tungsten heating.

    Most operators use a modest amount of cleaning, then adjust for dirty material, thickness and joint type. Start from the settings suggested in the manual for your own machine and change one thing at a time on offcuts.

    What does AC frequency change in the arc?icon-minus-redicon-plus-red

    Frequency is how many times per second the current alternates. A lower frequency gives a softer, wider arc that is forgiving and suits thicker material or wide beads. A higher frequency gives a tighter, stiffer, more focused arc that helps with fillet joints, edge welds, thin sheet and precise control around corners.

    There is no single correct figure. Try a few settings on offcuts of the same material and joint type, and choose the one where the puddle is easy to steer and the bead looks even.

    Should I choose a gas-cooled or water-cooled machine?icon-minus-redicon-plus-red

    It depends on the current you use and how long you weld without a break. Gas-cooled torches suit light to medium work and shorter weld times, and are simpler because there is no coolant to look after. Water-cooled setups use a separate cooling unit and a torch with a coolant circuit, which keeps the torch comfortable and protects it during long, high-current welding.

    Aluminium often needs more current than steel of the same thickness, so water cooling is common for heavier aluminium fabrication. Check the duty cycle rating for the current you actually plan to use.

    Single phase, three phase or multi-voltage: which supply do I need?icon-minus-redicon-plus-red

    Start by checking what your premises can supply. Single-phase machines run from a single-phase supply but are limited in maximum output, and larger ones may need a higher-rated socket than a standard one. Three-phase machines suit workshops with a three-phase supply and give more power for thicker material. Multi-voltage machines adapt to different supply voltages.

    Output may differ depending on the supply you connect to, so check the data plate and manual for your own machine, which give the rated output at each voltage. Have a qualified electrician confirm the supply, fuse rating and cable before installation.
