OPERATION INSTRUCTION
DC Welding Function Instruction
1. Turn on the power switch on the front panel, the current meter shows normally, and the fan begins
to work.
2. Turn on valve of the argon cylinder; adjust the current meter according to the need.
3.
When the AC/DC alter switch is on the “DC” position, it is AC arc welding and can weld the metal
such as stainless steel, iron and copper.
4.
When the local/remote alter switch is on the position of “OFF”, the current can be adjusted by the
knob on the panel,
while the switch is on the “ON” position, the welding current is adjusted by the
floor push.
5.
Choose the “pulse alter switch” according to the need. When the switch is on the down position, there
is no pulse, while on the up position, there is low frequency pulse. Adjust the
“frequency knob”
according to the need.
6. Adjust the pulse duty according to the need.
7. Adjust the value of the arc initiation and arc stop according to the need.
8. Set the peak value and the lowest value of the current according to the thickness of the work piece
(when the pulse switch is on low position, there is no current).
9. Press the control knob of the torch, the e electromagnetic valve begins to work, and the sound of the
HF arc initiation discharge is heard, and at the same time the argon flow from the nozzle of the
welding torch.
10. When the Tungsten is 2-4mm from the work piece, press the knob of the welding torch, the arc is
initiated and the HF arc initiation sound disappears and the machine is ready to work.
11. When the welding is finished, please adjust the gas sending knob to the suitable place to protect
the welding pipe.
12. During the argon arc welding, choose the 2T/4T switch for long welding or spot welding. When the
switch is on the “2T” position, the arc initiation current and the arc stop current doesn’t work, and
only the welding current can work.
13. When the switch is on the 4T position, press the torch switch and there is the arc initiation current,
while letting go the torch switch, there is arc stop current. Press the switch again, there is arc stop
current, while letting go the torch switch again, tHhe welding machine stop working.
