This warranty shall not apply to any welding machine which has been repaired or altered by unauthorized service departments in any way so as, in the judgment of HTP America, Inc., to affect its stability and reliability, nor which has been subjected to misuse, negligence, or accident.
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.

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. ...

Alternatively, and to obtain maximum duty-cycle and power output, you can run your Invertig 313 on 230 volt, 3- phase power, or you can run your Invertig 400 on 200 to 575 volt, 3-phase power. With the Invertig 313, the power draw on 230 volt, 3-phase power is 31.8 amps.
6) FRONT PANEL CONNECTIONS Fig. 2 Z—Negative Output Receptacle When TIG welding, connect the TIG torch to the negative output receptacle to weld Electrode Negative (EN; with the torch negative and the work positive). 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.

Invertig 313 vs. Invertig 400 The Invertig 313 is a 300 amp AC/DC TIG welder with single or 3-phase capability. The Invertig 300 runs on 208 to 240 volt input power, and features the same functions as the Invertig 400 but with less maximum output and a slightly lower duty-cycle.

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 13
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;...

The strongest effects and the best results occur when you set the difference between the peak amperage and the background amperage rather high. With the Invertig 313/400, you can adjust the pulse frequency from 0.4 to 999.9 PPS, the background amps from 10 to 90%, and the peak time (pulse-on time or duty) from 10 to 90%.

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 16
Now Let’s Talk Pulse How does pulse work? How do I set up the Invertig 313/400 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.

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 313/400. 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 18
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.

Fig. 40 The Invertig 313/400 allows you to adjust TIG hot-start in both AC and DC. Most other TIG welding machines, and all other high-end, brand name welding machines, feature a hot-start function that delivers a factory pre- set amount of hot-start, for a predetermined amount of Fig.

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.

Once you let go of the momentary switch button, the arc extinguishes and the post-gas flow timer engages (Fig. 57; 12.0 seconds in this instance).

In TIG 2T, when you press the momentary switch button the machine welds and when you let go, the machine stops. In TIG RESET, the process works different. Let’s take a look at the sequencer. Fig. 64 If you want to weld at a lower amperage, a swift flick of the momentary switch button allows you to weld at your lower set amperage (Fig.

Once you let go of the momentary switch button, the arc clears. Wait an additional six (6) seconds, and the extinguishes and the post-gas flow timer engages (Fig. Invertig will be back in the regular welding mode. 67; 12.0 seconds in this instance).

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 313/400 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.

14) Glossary Arc-Force Related to amps and volts when welding. When stick welding, the Pro Pulse 300 power source produc- es a CC, or constant current, output; in other words, the machine holds a constant amperage level, while the voltage varies according to the arc length, or the distance between the rod and the work surface—longer arc lengths increase voltage and shorter arc lengths decrease voltage.
