IGBT TECHNOLOGY<\/p>\n

Modern technology based on bipolar transistors with an insulated gate.\u00a0It combines the ease of control of field effect transistors with the high breakdown voltage and switching speed of bipolar transistors.\u00a0The use of IGBTs significantly extends the reliable operation of welding equipment.<\/p>\n

LEVEL OF SECURITY<\/p>\n

IP defines the degree to which the device is resistant to the penetration of solid and water contaminants.\u00a0IP23 means that the device is suitable for indoor use and is not suitable for use in the rain.<\/p>\n

MMA<\/p>\n

A method that uses a coated electrode, consisting of a metal core covered with a sheath.\u00a0The welder feeds the electrode as it melts into the workpiece so as to maintain a constant arc length.\u00a0The device enables welding with all types of electrodes, e.g. basic, cellulose, rutile or acidic.<\/p>\n

ARC FORCE<\/p>\n

The arc stabilizing function by maintaining the value of the welding arc voltage regardless of its length and facilitating the control of the amount of spatter.<\/p>\n

HOT START<\/p>\n

When the arc is struck, the welding current is temporarily increased in order to heat the material and the electrode at the point of contact and to properly shape the penetration and weld face in the initial phase of welding<\/p>\n

VRD<\/p>\n

The VRD function lowers the no-load voltage.\u00a0The correct voltage value is only restored just before the arc is struck.\u00a0This minimizes the risk of electric shock, but in some cases it may make it difficult to strike the arc.<\/p>\n

TIG AC\/DC<\/p>\n

Enables TIG welding with alternating current.\u00a0It is required for welding aluminum and its alloys.<\/p>\n

HF<\/p>\n

Welding with a tungsten electrode in a protective gas shield with a pilot arc (non-contact)<\/p>\n

WORK CYCLE<\/p>\n

The duty cycle is based on a 10-minute period. A duty cycle of 60% means that after 6 minutes of operation (when welding non-stop on 100% power 200A), a 4-minute break is required . 100% duty cycle means that the device can work continuously without interruption.<\/p>\n

POSITIVE CURRENT<\/p>\n

The current responsible for maintaining the welding process, the lower value of the current pulse.\u00a0It makes it easier to control the amount of heat introduced into the material.<\/p>\n

START CURRENT<\/p>\n

Current appearing in the circuit after pressing the button in the handle of the handle.\u00a0The higher the starting current, the easier it is to strike the arc.<\/p>\n

GAS PRE-FLOW TIME<\/p>\n

The time from pressing the button in the handle of the torch to the moment of arc ignition.\u00a0Normally it should be longer than 0.5 s to deliver the shielding gas to the torch nozzle outlet.\u00a0to cover the welding start point and the tungsten electrode.<\/p>\n

The pre-flow time should be longer in the case of a longer cylinder gas line.<\/p>\n

GAS POST FLOW TIME<\/p>\n

Time from arc extinction to gas valve closing.\u00a0to shield the solidifying weld pool from the air and to cool the tungsten electrode.<\/p>\n

Too short post-flow time may result in oxidation of the weld.<\/p>\n

DOWNDOWN TIME<\/p>\n

The time for the welding current to fall from the set value to zero or the value of the crater current.<\/p>\n

RISE TIME<\/p>\n

Welding current rise time from the initial current to the set welding current value.<\/p>\n

PULSE WIDTH<\/p>\n

The duration of the pulse allows you to adjust the penetration depth.\u00a0Increasing the width increases the depth of penetration, reducing the amount of heat introduced into the material, reducing the risk of burning through thinner sheets or smaller components.<\/p>\n

PULSE FREQUENCY<\/p>\n

The frequency at which the current pulse value changes between the welding current and the base current.<\/p>\n

AC FREQUENCY<\/p>\n

This function is useful when welding aluminum.\u00a0The higher the frequency, the better the quality of the weld and the better the focus of the arc.<\/p>\n

AC CURRENT BALANCE<\/p>\n

The ratio of the duration of the positive phase of the current to the negative one.\u00a0Reducing the balance introduces more heat into the material, resulting in a narrower weld and deeper penetration, while reducing the heat load on the tungsten electrode.<\/p>\n

Increasing the balance introduces less heat into the material, resulting in better cleaning, a wider weld and shallower fusion, but significantly stresses the tungsten electrode.<\/p>\n

PULSE TIG<\/p>\n

The function affects the shape of the weld and the focus of the arc.\u00a0Pulse welding also allows you to reduce the amount of heat supplied to the material and is used when welding thin materials.<\/p>\n

CRATE CURRENT<\/p>\n

Current used in some welding modes where the arc is not extinguished immediately after the downslope phase.\u00a0Allows you to fill the crater at the end of the joint.<\/p>\n

2T \/ 4T WORKING MODE<\/p>\n

2T – pressing the button in the handle of the handle turns on the ionizer and ignites the arc.\u00a0Welding is carried out with the button pressed.<\/p>\n

4T – pressing the button in the handle of the handle will turn on the ionizer and ignite the arc, then release the button and weld with the button released.\u00a0Pressing the button again will end welding.<\/p>\n
