INTIG 401 PULSE
DC Pulse Argon Welding Machine
1 Overview:
INTIG 401 PULSE series TIG welding machine adopts the high power IGBT and FRD
as the breaker, 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 401 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 401 PULSE
serials 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.
2 Working condition & Environment:
2.1 Input Power
2.1.1 The exact input voltage wave shape should be sine wave, the frequency
fluctuation should be no more than +1% of the rated value
；
2.1.2 The fluctuation of input voltage must be 15% of the rated value;
2.1.3 The unbalance rate of input voltage should be ≦5%.
2.2 Environment
2.2.1 Ambient temperature ranges:Welding temperature range: -10℃~+40℃,
Transportation and Storage temperature range: -25℃~+55℃
2.2.2 Relative humidity: ≤50% @ 40℃
≤90%@20℃
2.2.3 The dust, acid, corrosive gas or material around should not exceed the
normal content, except the one produced during welding;
2.2.4 Operating altitudes: less than 1000m;
2.2.5 Wind speed should be no more than 1m/s;
2.2.6 Keep the machine inside and dry all the times, do not locate where the
machine is exposed to direct sunlight and rain.
