General
In combination with the wire buffer on the hosepack, the integral wire drive motor can quickly reverse the wire electrode. Many different torch body designs facilitate easy access to the weld seam.
The welding torches are particularly robust and reliable, with an ergonomic grip, ball joint and perfect weight distribution for fatigue-free working.
The welding torches are available as gas-cooled and water-cooled versions. In conjunction with the available Multilock torch bodies, the welding torches can be used in an extremely wide range of applications. They are ideal for manual batch and single-piece production as well as for jobs in the workshop.
The hosepack is particularly well-suited to:- General light-gauge sheet applications
- Spatter-free MIG brazing of galvanised light-gauge sheets
- Joining steel to aluminium

Safety
WARNING!
Danger from incorrect operation and work that is not carried out properly.
This can result in serious personal injury and damage to property.
All the work and functions described in this document must only be carried out by technically trained and qualified personnel.
Read and understand this document in full.
Read and understand all safety rules and user documentation for this device and all system components.
WARNING!
Danger from electric current.
This can result in serious personal injury and damage to property.
Before starting work, switch off all the devices and components involved and disconnect them from the grid.
Secure all the devices and components involved to prevent unintentional restarting.
After opening the device, use a suitable measuring instrument to check that electrically charged components (such as capacitors) have been discharged.
WARNING!
Danger from electric current due to defective system components and incorrect operation.
This can result in serious injury and damage to property.
All cables, lines and hosepacks must be properly connected, undamaged, correctly insulated and adequately dimensioned at all times.
CAUTION!
Risk of burns from hot welding torch components and hot coolant.
This can result in scalding.
Before commencing any of the work described in this document, allow all welding torch components and the coolant to cool to room temperature (+25°C, +77°F).
CAUTION!
Danger from operation of water-cooled welding torches without coolant.
This can result in damage to property.
Never operate a water-cooled welding torch without coolant.
During welding, ensure that the coolant is circulating correctly – this will be the case if a regular return flow of coolant can be seen in the coolant container of the cooling unit.
The manufacturer will not be liable for any damages due to non-observance of the above mentioned points, and all claims against the warranty shall be void.
CAUTION!
Risk of coolant escaping.
This can result in injury and damage to property.
Seal the coolant hoses on water-cooled welding torches with the plastic stoppers fitted to them if the hoses are detached from the cooling unit or other system components.
CAUTION!
Risk of injury from moving parts.
This can result in injury and damage to property.
Close the cover over the feed rollers before using the welding torch.

Note regarding the inner liner with gas-cooled welding torches
NOTE!
If a plastic inner liner is used in the torch body of a gas-cooled welding torch, reduce the power figure shown in the technical data by 30%.
To operate gas-cooled welding torches at maximum power, use a steel inner liner in the torch body.
Inserting a steel or CrNi inner liner into the torch body

* Use the welding torch cutting pipe (gas = 40 mm, water = 50 mm)
Checking the clamping nipple
* Check the clamping nipple before commissioning and whenever the inner liner is changed. To do so, carry out a visual inspection:
- Left: brass clamping nipple with seal ring. You cannot see through the seal ring.
- Right: silver clamping nipple with see-through bushing
NOTE!
Incorrect or defective clamping nipple in push applications
Causes gas loss and poor weld properties
use brass clamping nipples to minimise gas loss
check that the seal ring is intact
NOTE!
Incorrect clamping nipple in push-pull applications
Tangled wire and increased abrasion in the inner liner when using a clamping nipple with seal ring
use silver clamping nipple to facilitate wirefeeding

Attaching the torch body
CAUTION!
Risk of damage to the welding torch.
Always tighten the union nut on the torch body as far as it will go.
NOTE!
Before fitting a torch body, ensure that the interface between the torch body and the hosepack is clean and undamaged.
NOTE!
In the case of water-cooled welding torches, increased resistance may arise when tightening the union nut due to the construction of the welding torch.
This is normal. Always tighten the union nut on the torch body as far as it will go.

Threading the wire electrode
CAUTION!
Risk of injury and damage from the welding current and accidental ignition of an arc.
Before starting work, disconnect the ground earth connection between the welding system and the workpiece.
CAUTION!
Risk of damage to the welding torch from sharp end of wire electrode.
Deburr the end of the wire electrode well before threading in.
CAUTION!
Risk of injury due to springiness of spooled wire electrode.
When inserting the wire electrode into the 4-roller drive of the wirefeeder, hold the end of the wire electrode firmly to avoid injuries caused by the wire springing back.
1
2
CAUTION!
Risk of injury and damage from wire electrode emerging.
While working:
Hold the welding torch with the end directed away from the face and body
Wear suitable protective goggles
Do not point the welding torch at people
Make sure that the wire electrode does not touch any conductive or earthed parts (e.g. housing)
The covers of the wire buffer and the grip must be closed.
NOTE!
Before feeding in the wire electrode, lay out the hosepack in a straight line as shown below.
Maximum permitted feeder inching speed = 10 m/s.

Setting the contact pressure
Only set the contact pressure once the wire electrode has been threaded in.
| * | Use the values shown on the inside of the cover as a guide when setting the contact pressure. |
NOTE!
The contact pressure is set as follows:
Turn the screw counter-clockwise = reduce the contact pressure
Turn the screw clockwise = increase the contact pressure

Removing the torch body
CAUTION!
Risk of burns from hot coolant and hot torch body.
Before carrying out any work, allow the coolant and torch body to cool to room temperature (+25 °C, +77 °F).

Care, maintenance and disposal
General
Regular preventive maintenance of the welding torch is essential if trouble-free operation is to be ensured. The welding torch is subjected to high temperatures and heavy soiling. The welding torch therefore requires more frequent maintenance than other components in the welding system.
CAUTION!
Risk of damage from improper handling of the welding torch.
This can result in severe damage to property.
Do not strike the welding torch on hard objects.
Avoid scoring and scratches on the contact tip.
Do not bend the torch body under any circumstances.
