Operation
(1)
Verify that the input gas supply pressure is set to 5kg /cm2 (5 Bar).
(2)
Pull the regulator cap out, gradually turn regulator cap to adjust gas pressure to 2.5-3.5 kg/cm2
(2.5-3.5 Bar) and push the regulator cap back in.
(3)
Switch on the power source. The power light (red) should illuminate. Adjust the cutting
current and choose desired post gas flow time with the toggle switch.
(4)
Place the tip of the torch at the edge of the work piece, makes sure the tip is vertical to the
work piece. When piercing, the tip should have an angle away from operator. After arc starts,
slowly rotate the torch to upright position. This is to blow the melted metal away and is
particularly important when cutting thicker material. Make sure that the torch is pointed away
from you and the people near you to avoid any danger from sparks and hot metal.
