Connecting the welding cables
Notes on laying welding current cables
•
Completely unroll welding current cables, welding torches and intermediate hose packages.
•
Avoid loops!
•
In general, the cable must not be longer than necessary.
•
Lay excess cable lengths in a meandering manner.
TIG welding: connection of welding torch, workpiece lead, and shielding gas supply
•
Insert the welding current plug of the welding torch into the connection socket, welding current
"–," and lock by turning to the right.
•
Fasten the shielding gas connection of the welding torch to the quick connection for the gas
lead and lock it.
•
Insert the control cable plug of the welding torch into the connection socket for the control ca-
ble/welding torch, and tighten it.
• Insert the cable plug of the workpiece lead into the connection socket, welding current "+," and
lock by turning to the right.
MMA welding: connection of electrode holder and workpiece lead
The polarity depends on the information provided by the electrode manufacturer on the electrode pack-
aging.
•
Insert the cable plug of the electrode holder either into the connection socket, welding current
"+" or "–," and lock by turning to the right.
• Insert the cable plug of the workpiece lead either into the connection socket, welding current "+"
or "–," and lock by turning to the right.
The welding machines are equipped with quick connectors for connecting the earth cable and the TIG
welding torch. In order to achieve optimal welding results, make sure that all connections of the welding
cables are tight and that the insulation is not damaged.
Make sure that the earth cable is connected to the workpiece as close as possible to the welding loca-
tion. Earth connections made at distant points reduce the efficiency and increase the risk of electric
shock and stray currents.
The electrode is both an arc carrier and an additional material. It consists of an alloyed or unalloyed
core wire and a jacket. The purpose of the jacket is to protect the weld pool from harmful air ingress and
to stabilize the arc. On the other hand, a slag forms that protects and shapes the weldseam. Almost all
metals can be welded with electrode welding.
