INTIG 250 PULSE DC Pulse Argon Welding Machine
1. Overview :
INTIG 250 PULSE series TIG welding machine adopts the high power IGBT, the invert
frequency reaches 20KHZ. The small mid-frequency transformer replaced the heavy industrial
frequency transformer, which with advantages as: high efficiency, low non-load loss, stable current,
energy saving, material saving and high reliability etc.
INTIG 250 PULSE series TIG arc welding machine has all functions required by welding
technique: high frequency arc striking, gas pre-send (adjustable), initial current (adjustable), current
up-slope (adjustable), current down-slope (adjustable), crater current (adjustable), gas post-off etc.
Except for DC welding mode, the INTIG 250 PULSE series has pulsed welding mode, the advantage
is: welding current high and low interchange working, so it has better arc and stronger weld seam
which is decided by the welding machine parameter.
This series of welding machine can used for almost all metal work pieces except magnesium-
aluminum alloy, such as stainless steel, pipeline, boiler, aerospace equipment etc.
