Operating guide
Warning!
Operating the welding machine incorrectly can cause serious injury and damage. Do not use the
functions described here until you have read and completely understood all the following guides:
-“safety rules”
-“before commissioning”
Warning!
Electric shock is very dangerous. As soon as the power source is switch on, the welding
electrode is power on. Make sure that the electrode does not touch any person or conductor or grounded
parts (e.g. lifting appliance etc.)
SMAW welding with basic electrode: E7016/E7018
1.Connect electrode holder with output terminal (+), connect work piece with output terminal (-);
2.Place switch on “ON” position, power on;
3.Choose “Panel control” mode on control panel;
4.Choose “Amp/Volt” switch on “Amp” position;
5.Adjust arc start current, arc force current, welding current according to electrode diameter, welding position;
6.Welding
Gouging
Note!
“GOUGING” process only is available for the machine which rated current is
≥
500A.
1.Switch off the mains switch;
2.Plug one end of the ground cable to the output terminal (-);
3.Connect the other end of the ground cable to the work piece;
4.Plug the gouging torch cable to output terminal (+);
5.Connect the gas hose to gas outlet of the air compressor or other gas supply tube;
6.Switch on the mains switch;
7.Select “SMAW” by the SMAW/TIG switch on front panel;
8.Set the required current value by rotating “welding current” knob;
9.Increase arc force current properly;
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.
