Set up and operation for AC PULSE TIG Welding

1. Select AC Pulse by pushing

selector key to cycle through to

illuminate AC Pulse icon.

2. Select Peak Current by pushing the selector button to

cycle through to illuminate the Peak Current Icon

3. Turn the Adjustment Knob to set the

Peak Current at 150A

(Range is 10-200 Amps)

4. Select the Base Current by pushing the selector key to

cycle through to illuminate the Base Current Icon

5. Turn the Adjustment Knob to set the Base

Current at 60A (Range is 10-200 Amps)

The Razorweld 200ACDC machine has digital pulse frequency control. All the parameters for AC & DC Pulse TIG

welding - Peak Amp, Base Amp, Pulse Frequency and Pulse Width are easy to set via the digital control panel.
EXAMPLE OF PULSE AC TIG WELDING - SETUP PARAMETERS:

Material = Aluminium x 3.0mm / Tungsten Electrode = 2.4mm Zirconiated / Gas = Argon

(1) Prepare the machine for AC TIG welding as per the AC TIG operating guide on page

(2) Set the Peak Current at 150 Amps

(3) Set the Base Current around 40% (Base Current is % of the Peak Current eg 40% of 150 = 60 Amps)

(4) Set the Pulse Frequency around 2Hz (pulses per second)

(5) Set the Pulse Width around 60% (the current will spend 60% at Peak Current & 40% at Base Current)

You can experiment by changing any of the variables to see what effect it has over the welding and what the end

result can be, but it is suggested to change only one variable at a time and then check the welding result.
