Wire inch
With wire inch, wire feed motor and mechanism can be operated without starting the power source.
The filler wire can be driven into the wire feed unit and gun also by pressing the welding gun switch, but then the
power source will start and the wire becomes live, which can cause a danger of accidental contacts with surrounding
objects!
6.3. KMW TIMER FUNCTIONS
2 / 4-sequence procedure
Welding with the 2-sequence trigger procedure
1. Switch pressed: welding starts
2. Switch open: welding stops
Spot, cycle arc and continuous welding (only in the 2-sequence procedure)
Spot welding
1. Set the spot time with potentiometer.
2. Press the gun switch: welding starts
3. Welding ends automatically after the preset time.
Cycle arc welding
1. Set the welding cycle time with the potentiometer. The pause time is adjusted automatically.
2. Press the gun switch: cycle welding is continued as long as the switch remains pressed.
7. OPERATION DISTURBANCES
The use and working environment of the equipment should be taken into consideration when planning the maintenance
of the wire feed unit. Careful use and preventive maintenance will help to ensure problem-free operation.
The following maintenance operations should be carried out at least every six months:
Check:
– The wear of feed roll grooves. Excessive wear of grooves will cause problems in wire feed.
– The wear of wire guide tubes in wire feed unit. Worn-out feed rolls and wire guide tubes should be
replaced.
– The wire guide tube in the gun should be set as close to the feed rolls as possible, but not in contact with
them. The wire must be in a straight line from the end of the tube to the feed roll groove.
– Reel brake adjustment
– Electric connections
* Oxidised couplings must be cleaned.
* Loose couplings must be tightened.
Clean dust and dirt from the equipment.
In case of problems contact your Kemppi dealer.
When using compressed air, always use proper eye protection.
10 – KEMPOWELD WIRE 200 / 0546
In the instruction labels of filler wires, starting points for adjustment are
given. Fine-adjustment should be carried out case-specific.
1. Aluminium melts much quicker than other materials, so the burn
back time can be shorter.
2. Steel and especially flux cored wires require a longer burn back time
than stainless materials.

3. Thicker filler wires require a longer time. Also, when the wire feed
speed increases the burn back time must be extended.
4. Memory scale for potentiometer.
5. Wire inch
Welding with the 4-sequence trigger procedure
1. Switch pressed: shielding gas flows
2. Switch open: welding starts
3. Switch pressed: welding stops
4. Switch open: gas flow stops after the post gas time
