    In the AC TIG mode, the following wave forms are available: square wave, soft square wave, and triangular wave. The Invertig 301 is a single-phase only machine, it runs on 208 to 240V. The Invertig 400 offers the ability to run on single- phase power, from 208 to 240V, or on 3-phase power, from 200 to 575V.

  • Page 5: Safety Suggestions

    3) SAFETY SUGGESTIONS It is forbidden for people with PACEMAKERS to use or come near the machine. When welding near sensitive electronics, for example in hospitals or assisted living homes or around computers or computer control modules in vehicles, we STRONGLY recommend turning off HF (high-frequency arc start). Even an AC arc on a modern inverter can be ignited in lift-arc mode! HF travels long distances, 10 to 20 feet are very common in some instances, and HF can interfere with electronics in neighboring buildings if they are on the same transformer! Unlike regular welding currents, that travel the path of least resistance, HF is unpredictable.
  • Page 6 Noise can damage your hearing. Protect yourself suitably to avoid hearing damage. The welding arc can cause burns. Keep the tip of the welding gun/torch far from your body and from other persons. For more information, refer to the following standards and comply as applicable. ) ANSI Standard Z49.1 SAFETY IN WELDING AND CUTTING, obtainable from the American National Standards Institute, 1430 Broadway, New York, NY 10018.

When using your Invertig to TIG weld, all work will be done in EN. When Stick welding in Direct Current Electrode Negative (DCEN), plug the optional electrode holder into the negative output receptacle.

    Contains the serial number of your Invertig 301/400. The serial number consists of two letters and six numbers. S—On/Off Switch The switch turns your Invertig 301/400 on and off. Set the switch to position 0 for off, and set the switch to position 1 for on.
  • Page 12 Invertig 301 vs. Invertig 400 The Invertig 301 is a 300 amp AC/DC TIG welder with single-phase capacity only. The Invertig 301 runs on 208 to 240 volt input power, and features the same functions as the Invertig 400 but has less maximum output and a slightly lower duty-cycle.
  • Page 13 Soft Square Wave: The soft square wave provides a more sinus like wave form, which allows for a softer arc and a more fluid weld puddle, and it does so while creating significantly less noise. The SOFT symbol on the right-hand side of the LCD above the 3-phase symbol (Fig.
  • Page 14 AC Balance Balance refers to the time the arc spends above or, in the case of HTP machines, below the zero line. What does that mean? Imagine you weld AC and you set your frequency not to 100Hz but to 1Hz (1Hz used for the purpose of easy demonstration;...
  • Page 15 In place of high-speed pulse, we recommend the use of the triangular wave form instead, which achieves similar results. With the Invertig 301/400, you can adjust the pulse frequency from 0.4 to 20.0 PPS, the background amps from 10 to 90%, and the peak time (pulse-on time or duty) from 10 to 90%.
  • Page 16 j) Pulse in Stick (Square Wave Only) Advantages of Pulse Welding Pulse welding includes ALL of the following advantages, but not all at the same time. At a later point in the manual, we cover, in more detail, suggested settings regarding how, when, and where certain situations apply. ...
  • Page 17 Now Let’s Talk Pulse How does pulse work? How do I set up the Invertig 301/400 to pulse weld in Stick mode? For manufacturing or critical code repairs, welding procedures are typically specified. These welding procedures spell out everything including, but not limited to, pre-heat of the part, alloy of the filler rod, amperage setting, travel speed, bead size, multi-pass weld number of passes (if applicable), inter-pass temperature, post-heat, and so on.
  • Page 18 Unlike regular welding currents that travel the path of least resistance, HF is unpredictable. Lift start, not to be mistaken for scratch-start, can be used to ignite a DC or an AC welding arc with the Invertig 301/400. If you use a foot pedal, turn HF off in the menu, and then touch the clean and cold tungsten electrode to the clean material you plan to weld on.
  • Page 19 without HF and by depressing the foot pedal before the tungsten touches the base metal. At this point, whatever you set the machine to (however much the foot pedal is depressed) the arc will strike at that amperage. This is, by far, the least preferable arc starting method with the Invertig.

    q) Smart Water-Cooler Operation and Control The smart water-cooler is controlled by the welder, but the smart water-cooler also controls the welder. The pump and the fan in the cooler are on-demand, meaning they only run if and when necessary. The fan is also variable speed. If the fluid level in the cooler is low, the cooler communicates with the welding machine, turns the welding output off, and displays an error message.

  • Page 29 When you let go of the momentary switch button, the c) TIG 4T machine goes into t1 (slope up), which we set to 1.5 seconds (Fig. 54). TIG 4T is a very popular process in Europe where people typically use a momentary (arc on/off) switch instead of a foot pedal.

  • Page 33 However, these numbers change with the selected welding amperage and the ambient temperature. In reality, very few can keep track of welding time like this, so we equipped the Invertig 301/400 AC/DC with a highly sophisticated over-heat protection. The machine monitors the temperature of several vital internal components. Just before temperatures venture outside of the safe operating range, the machine displays a message to the operator, the cooling fan continues to run, and the welding output is shut down for four (4) minutes.
