The TIG welder for ambitious welding jobs

The powerful TIG welder ENTRIX315A convinces with precise welding results that exceed every expectation. With the TIG welding method, you can weld with direct current (DC) or alternating current (AC), meaning you can even effortlessly weld aluminium. You can also use the pulse function or use the device for MMA welding.

Optimal welding results for TIG AC/DC welding

The TIG welding machine's digital control panel is very clearly arranged. Each of the parameters can be simply selected and the desired value for gas post-flow time or end current, for example, set using buttons. Other common operating modes for TIG welding, such as the choice between DC or AC mode or easy switching between 2- and 4-stroke welding, can be easily and directly set on the control panel. The device can also be operated only with air cooling up to a welding current of 150 A. If you want to work with high welding current values, you should attach an external water-cooling system (not included) to the device. When water-cooled, the MMA welder with an impressive 315 A can weld nearly all melting types of metal and their alloys such as aluminium, copper, nickel or steel.

For TIG welding, simply activate the pulse frequency on the control panel which will enable you to precisely weld thin sheets, among other things. You can select various parameters such as pulse frequency, pulse current or base current. You can precisely set the value, which is shown on the large display, using two buttons. Alternatively, you can also control the welding current using a foot pedal. The Easy mode automatically matches all other parameters to the selected current.

For MMA welding, you should first set the strength of the of the welding current on the control panel. For balanced welding results, the device is equipped with the functions Hot Start, Arc Force and Anti-Stick. MMA welding is primarily used for iron or steel, as well as for alloys such as cast iron or copper. The cart is equipped with four wheels to facilitate mobility and has space for gas cylinders needed during TIG welding.

This device does not include a high voltage plug!

MOSFET

The welder is equipped with a MOSFET transistor. This technology represents the highest standards of performance combined with compact and lightweight design. The result is 93% efficiency! The welding current is very stable and thus ensures a perfect weld.

PROTECTIVE GAS

TIG/MIG and MAG welding require a protective gas. Inert gases, such as argon and helium, as well as active gases (for example carbon dioxide) and other mixtures can be used. The solenoid valve regulates the flow of gas. The valve is operated via a button on the torch.

EARTHING SYSTEM

On the back of every welding machine is a screw with an earthing mark. Before use, earth the unit via a cross-section cable, which must be at least 6 mm².

 
GROUND TERMINAL CONNECTOR

 

 
MMA WELDING CABLE CONNECTOR

 

 
TIG TORCH CONNECTOR

 

 
FOOT PEDAL CONNECTOR

This unit can also be operated using a foot pedal.

 
SUPPLY VOLTAGE

This device works with a 3-phase connection (400 V +/- 10 %).

 
COOLING SYSTEM CONNECTIONS

If welding with more than 200 A it is recommend that a cooler is used. The connections of the welding device and the cooler-lines are marked accordingly with colours.

 
NON-CONTACT HF-IGNITION

A non-contact high-frequency ignition in TIG mode ensures a cleaner weld starting point.

 
GAS PRE-FLOW TIME

This is the time taken from the moment of pressing the torch button to that of the electric arc igniting. During this process the solenoid valve opens and the released gas pushes the oxygen from the gas lines and in doing so, forms a protective atmosphere for the arc.

STARTING CURRENT

Value of the arc ignition output current. This current can be adjusted at will. For precision welding, it is recommended to start with reduced power, weld smoothly and eventually adjust the current accordingly.

CURRENT RISE TIME

The time taken by the output power to rise to that of the welding current’s value.

 
WELDING CURRENT

 

 
DOWN SLOPE TIME

The time taken of the output welding current to lower to that of the terminal current.

 
FINAL CURRENT

The output current value before the end of the weld. Welding with the final current helps prevent a crater forming at the end of the weld.

 
GAS POST-FLOW TIME

The time after the weld is finished in which gas continues to flow from the torch; this cools the burner and protects the weld from oxidation.

 
PULSE

This function reduces the heat to the material. It is primarily suitable for welding thin plates. If MIG welding is used, it is perfect for aluminium welding.

 
PULSE FREQUENCY

The frequency of impulses during pulse mode.

 
IMPULSE CURRENT

The maximum value of the electric current while in pulse mode.

 
BASE CURRENT

The current which maintains the arc while in pulse mode.

 
POWER FACTOR CORRECTION

This is the percentage difference of the time between the positive and negative direction of the current during a welding period. This feature allows control of the width of the welding seam and the depth of penetration.

CLEAN SCOPE - AC STROMBALANCE PARAMETER

This is the percentage difference between the positive and negative welding current value during a period.

 
2-STROKE

Start the weld by placing pressure on the torch button. Stop the process by releasing the button.

 
4-STROKE

By pressing the torch button the solenoid valve opens. allowing the gas to flow in. The gas pre-flow ignites the arc at the pre-set current. Releasing the burner button initiates a rise in the current to that of the pre-set welding current. The welding process stops once you press the burner button again.

Show moreShow less
 
HOT START

Through automatically boosting the tension at the ignition of the arc, this function facilitates the electrical arc ignition. After ignition, the unit automatically returns to the pre-set voltage.

Show moreShow less
 
ARC FORCE

The current value increases automatically when the arc is shorter.

 
ANTI-STICK

This function helps to prevent overheating of the electrode by switching off the welding current when the electrode sticks to the material.

 
TIG WELDING

A welding method in which the arc is maintained through an electrical current supplied from a non-consumable electrode. The arc is protected from the access of air by an inert gas.

MMA WELDING

Electrode welding with a coated electrode.

 
POWER SWITCH

 

 
"2T / 4T" SELECTION SWITCH

Choose between the 2T and 4T mode.

 
TIG AC/DC MODE SWITCH

TIG welding is divided into AC (alternating current) and DC (direct current) welding.

 
PULSE FUNCTION SWITCH

Used to switch the pulse function on and off.

 
SWITCH BETWEEN THE WELDING METHODS

By using the SHIFT key the welding mode can be selected.

 
PROG

The welding unit can internally save programs. You can start the desired program by pressing the button PROG.

 
SAVE

The unit can store several welding programs digitally under selected numbers, for example programs specific to the requirements of certain materials.

 
DISPLAY

Shows the welding / cutting parameters.

 
OVERLOAD / FAULT LED

The LED light indicates overheating or a malfunction.

Can I use this device to weld aluminium?
