that the wire can still be moved and the roller stops automatically after the wire guide has been braked.
6. Operation
6.1 Setting
Since the welding set must be set to suit the specific application, we recommend that the settings be made on the basis of a test weld.
6.1.1 Setting the welding current
The welding current can be set to 6 different levels using the ON/OFF/Welding current switch (Fig. 1/7). The required welding current depends on the material thickness, the required penetration depth and the welding wire diameter.
6.1.2 Setting the wire feed speed
The wire feed speed is automatically adjusted to the current setting. The final wire feed speed setting can be made on the welding wire speed controller (Fig. 1/14). We recommend that you start the setting work at level 5 which is the middle value, and then adjust it from there. The required quantity of wire depends on the material thickness, the penetration depth, the welding wire diameter and also of the size of the gap to be bridged between the workpieces you wish to weld.
6.1.3 Setting the gas delivery rate
The gas delivery rate can be infinitely adjusted on the pressure reducer (Fig. 4/19). It is shown on the pressure gage (Fig. 4/20) in liters per minute (l/min). Recommended gas delivery rate in rooms with no drafts: 5 – 15 l/min.
To set the gas flow rate, first release the clamp lever (Fig. 28/G) on the wire feed unit to prevent unnecessary wire wear (Fig. 5.4.3). Connect to the mains outlet (see point 5.3), set the ON/OFF/Welding current switch (Fig. 1/7) to setting 1 and press the burner switch (Fig. 5/25) to start the gas flow. Now set the required gas delivery rate on the pressure reducer (Fig. 4/19).
Turn the rotary knob (Fig. 4/24) counter-clockwise: Lower gas delivery rate
Turn the rotary knob (Fig. 4/24) clockwise:
Higher gas delivery rate
Secure the clamp lever (Fig. 28/G) to the wire feed unit again.
6.2 Electrical connection
6.2.1 Mains connection
See point 5.3
6.2.2 Connecting the earth terminal (Fig. 1/10) Connect the welding set's earth terminal (10) in the immediate vicinity of the welding position if possible. Ensure that the contact point is bare metal.
6.3 Welding
When all the electrical connections for the power supply and welding current circuit have been made and the shielding gas has also been connected, you can proceed as follows:
The workpieces for welding must be clear of paint, metallic coatings, dirt, rust, grease and moisture in the area where they are to be welded.
Set the welding current, wire feed and gas flow rate (see 6.1.1 - 6.1.3) as required.
Hold the welding screen (Fig. 3/17) in front of your face and move the gas nozzle to the point on the workpiece where you wish to complete the weld. Now press the burner switch (Fig. 5/25).
When the arc is burning, the welding set will feed wire into the weld pool. When the weld nugget is large enough, move the burner slowly along the required edge. Move it to and fro if necessary to enlarge the weld pool a little.
Find the ideal setting of the welding current, wire feed speed and gas delivery rate by carrying out a test weld. Ideally an even welding noise will be audible. The penetration depth should be as deep as possible, but the weld pool must not be allowed to fall through the workpiece.
6.4 Safety equipment
6.4.1 Thermostat
The welding set is fitted with an overheating guard that protects the welding transformer from overheating. If the overheating guard trips, the control lamp (3) on your set will be lit. Allow the welding set to cool for a time.
7. Cleaning, maintenance and ordering of spare parts
Always pull out the mains power plug before starting any cleaning work.
