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
Note!
This is multi-operator welding machine, which integrates 3 units ARC400 machines into one case.
Three outputs allow three operators to work at the same time or work separately.
