4. Preparing for Operation

4.1Placing the machine

A Caution!

Always stand the machine on its feet only.

The machine draws in air at its front and bottom, which is given off through the ventilating slots at the rear. Ensure an unhindered airflow. The distance of the machine to walls or other equipment must be at least

20cm.

5.Operation

A Caution!

Check all connections and supply lines before turning on.

3 Note:

For manual arc welding this machine uses the Hot-start, Arc-force and Anti-stick functions.

Hot-start function

When contacting the weld metal with the electrode, the set welding current is increased for a short period to ensure that the arc will start.

This brief increase of the welding current is limited to the maximum electrode cur- rent.

Arc-force function

During the welding process the machine keeps the energy (heat) brought into the weld metal at a constant level, even if the distance between electrode and weld pool varies.

Anti-stick function

If the machine detects a short-circuit in the welding process, it will switch to min- imum current within 0.5 sec to keep the electrode from burning out.

5.1Manual arc welding

1.Connect the earth cable to the – pole.

2.Connect the welding cable to the + pole.

A Caution!

Note information on polarity shown on the packaging of the elec- trodes used; reverse polarity, if nec- essary.

A Caution!

For manual arc welding the Lift-arc ignition must be disabled. To check, turn the rotary switch counter- clockwise.

3.Attach earth cable at a suitable loca- tion of the workpiece.

4.Turn master switch ON.

5.Set desired welding current.

The welding machine is now opera- tional.

5.2TIG welding

When using a TIG welding torch (optional accessory), both models can also be used for TIG welding.

1.Connect the welding current cable of the TIG torch

(– pole).

2.Check the gas supply to the TIG torch.

3.Attach the earth cable at a suitable location of the workpiece (+ pole).

4.Turn master switch ON.

5.Set desired welding current.

6.Activate Lift-arc ignition.

To check, turn the rotary switch clockwise.

The welding machine is now opera- tional.

TIG welding

The arc can only be started by touching the workpiece with the electrode (Lift-arc ignition).
