12.Adjust down slope time according to welding current value;
13.Open gas valve of shielding gas regulator, press torch trigger, adjust flow rate, release torch trigger;
14.Press torch trigger, HF arc starting;
15.Welding: 2 step - press and hold torch trigger; 4step - release torch trigger after arc is established;
16.Stop arc: 2 step - release torch trigger, current down slopes until arc stops; 4 step - press and hold torch
trigger, current down slopes until arc stops, and then release torch trigger;
17.Post gas flow for about 3~5s, close gas valve of shielding gas regulator.
Gouging
1.Switch off the mains switch;
2.Use short circuit copper block to connect two positive output terminals, then connect gouging torch cable with
short circuit copper block;
3.Use short circuit copper block to connect two negative output terminals, connect ground cable with short circuit
copper block, then connect the other end of the ground cable to the work piece;
4.Connect the gas hose to gas outlet of the air compressor or other gas supply tube;
5.Switch on the mains switch;
6.Select “Gouging” by the SMAW/TIG/Gouging switch on front panel;
7.Set the required current value by rotating “welding current” knob;
8.Increase arc force current properly;
9.Adjust arc length “L/S/M” switch on “L” position;
10.Open the gas valve of the compressed air, and regulate the needed shielding gas flow and pressure;
11.Choose proper carbon rod according to current;
12.Open gas valve on gouging torch, make gas flow towards to work piece;
13.Start Gouging.
