6.Adjust arc start current, arc force current, welding current according to wire diameter, welding position;
7.Adjust “L/S/M” switch on control panel according to welding cable length;
8.Welding
Simple TIG welding
1.Screw shielding gas regulator onto the gas cylinder and tighten it; connect gas hose with shielding gas regulator
and gas inlet on welding machine rear panel;
2.Connect torch with output terminal (-), connect work piece with output terminal (+);
3.Place switch on “ON” position, power on;
4.Choose “SMAW/TIG” switch on TIG position;
5.Choose “Panel control” mode on control panel;
6.Choose “Amp/Volt” switch on “Amp” position;
7.Adjust welding current according to plate thickness;
8.Open gas valve of shielding gas regulator, adjust flow rate (if use V type torch (with air valve), need to open the
air valve);
9.Scratch arc starting;
10.Welding;
11.Pull out the electric arc
12.Post gas flow for about 3~5s, close gas valve of shielding gas regulator (if use V type torch (with air valve), may
close the air valve).
HF TIG welding
1.Screw shielding gas regulator onto the gas cylinder and tighten it; connect gas hose with shielding gas regulator
and gas inlet on welding machine rear panel;
2.Connect torch with output terminal (-), connect work piece with output terminal (+);
3.Place switch on “ON” position, power on;
4.Choose “SMAW/TIG” switch on TIG position;
5.Choose “Panel control” mode on control panel;
6.Choose “Amp/Volt” switch on “Amp” position;
7.Select 2 step/4 step;
8.Adjust welding current according to plate thickness;
9.Adjust down slope time according to welding current value;
10.Open gas valve of shielding gas regulator, press torch trigger, adjust flow rate, release torch trigger;
11. Press torch trigger, HF arc starting;
12.Welding: 2 step - press and hold torch trigger; 4step - release torch trigger after arc is established;
13.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;
14.Post gas flow for about 3~5s, close gas valve of shielding gas regulator.
