Operation

Switching the appliance on and oﬀ

♦ Switch the welder on and oﬀ using the main switch .

If you do not intend to use the welder for an extended period, remove the

plug from the power socket. This is the only way to completely de-energise

the appliance.

Setting the welding current

■ Use the switches

on the front of the welder to set the required

welding current.

■ If, for example, the MIN switch

und the switch 1 are set to the

up position, the welding current is 48 A and the duty cycle is at 60%.

■ If the MAX switch und the switch 2 are set to the down position,

the welding current is 90 A and the duty cycle is at 10%.

■ The required welding current is dependent on the diameter of the welding

wire being used, the material thickness and the desired penetration

depth.

MIN MAX

1 48 A 70 A

2 60 A 90 A

Adjusting the wire feed

■ To achieve a consistent weld result, you can make ﬁne adjustments to

the wire feed using the setting wheel for the wire feed

We recommend using a setting in the middle range to start with and

then increasing or reducing the speed as required.

■ The required welding ﬂow is dependent on the diameter of the welding

wire being used, the material thickness and the desired penetration

depth as well as the bridging distance between the two pieces being

welded.

Overload protection

■ The welder is protected against overheating by an automatic protection

appliance (thermostat with automatic restart) metal clad. The protection

appliance interrupts the power supply in the event of an overload and

the yellow overload protection control lamp lights up.

■ If the protection appliance activates, allow the appliance to cool down

(approx. 15 minutes). As soon as the yellow overload protection control

lamp

goes oﬀ, the appliance is again ready for use.

Welding mask

WARNING! HEALTH HAZARD!

► If you do not use the welding mask, the harmful UV radiation and the

heat coming from the electric arc can damage your eyes.

–

Always use the welding mask when you weld.

Welding

WARNING! RISK OF BURNS!

► Welded, hot workpieces are very hot so that you could burn yourself.

–

Always use pliers to move welded, hot workpieces.

After you have connected the welder to the power, proceed as follows:

♦ Connect the earth cable to the workpiece that is to be welded using

the earth clamp

Ensure that there is a good electrical connection.

♦ The workpiece should be free of rust and paint where the weld is to

made.

♦ Select the desired welding current and the wire feed depending on

the welding wire diameter, material thickness and desired penetration

depth.

♦ Switch the appliance on.

♦ Hold the welding mask

in front of your face and guide the torch

nozzle

to the position on the workpiece where you want to weld.

♦ Press the torch button

to generate an electric arc.

Once the electric arc is burning, the appliance feeds wire into the weld

pool.

♦ Once the weld nugget is big enough, guide the torch

slowly along

the desired edge.

The distance between the torch nozzle and the workpiece should be

as small as possible (never more than 10 mm).

♦ If required, oscillate a little to increase the size of the weld pool.

For inexperienced welders, it is often diﬃcult initially to create a decent

electric arc, i.e. in terms of the correct setting of welding current and wire

feed rate.

♦ You can work out the ideal settings for the welding current and the

wire feed rate by carrying out trial welds on a test piece.

A properly set electric arc has a mild, uniform buzzing tone.

The penetration depth should be as deep as possible, the weld pool,

however, should not be able to fall through the workpiece.

If you hear a raw or hard rattle, reduce the wire feed rate and switch

up to a higher load level (increase the welding current).

If the wire feed rate is too high and/or the welding current too low, the

welding wire cannot melt properly and dips repeatedly into the weld

bed as far as the workpiece.

A quiet dull sound with a guttering electric arc indicates that the wire

feed is insuﬃcient.

♦ Increase the wire feed rate or switch to a lower welding current.

If the welding current is too high, the wire will melt before it even

reaches the weld bed. This leads to droplet formation on the welding

wire as well as splash and an irregular electric arc.

♦ The slag may not be removed until the weld has cooled down.

To resume a weld on an interrupted joint:

♦ Start by removing the slag at the starting point.

♦ Ignite the electric arc in the groove, guide it to the continuation point,

melt properly and then continue the weld joint.
