To set up.
•
Before starting make sure that the end of the welding wire has been dressed and burrs and sharp edges
removed to prevent internal scoring of the torch liner
•
Open the Pull-Mig Handle cover
•
Unscrew the tension knob
•
Open the pressure arm assembly
•
Toggle feed the wire from the machine until it emerges from the liner.
•
Carefully and slowly feed the wire into the neck liner nipple.
•
Close the pressure arm assembly.
•
Tighten the tension knob so it is fully wound down and locked into position
•
Close the handle cover
The pressure arm is factory set to deliver the correct amount of side force to the drive roll.
We do not recommend changing this setting.
Water-cooled Pull – Mig torches.
If you have purchased a Water-Cooled variant, the water connections are industry standard and are marked blue (showing the cold
water inlet) and red (showing the hot water outlet)
We recommend a good quality water coolant additive is added to the cooling fluid, this will enhance cooling through the torch body
and will prolong torch hose life. It will also prevent frost damage to the torch internal components.
When first connecting a water-cooled variant, run the cooler before you weld to remove any trapped air pockets and remember to
check the water levels in the cooler after this startup check. An average 8m torch will hold around 0.5 liters of coolant. After welding,
we recommend that you run the water cooler for at least one minute to cool all the torch’s internal components. When removing a
water-cooled torch from a recirculator and to prevent loss of coolant from the torch, use the red and blue stoppers that are supplied.
We recommend draining the torch of coolant if it is not going to be used for any length of time.
You will require a water cooler ( recirculator ) with the following specification:
•
Minimum water flow : 1.2 l/m
•
Minimum inlet pressure :2.0 bar
•
Minimum cooling capacity :1600W
•
Maximum inlet pressure 5.0 bar
•
Maximum water inlet temperature 50 degrees C
We strongly recommend that a flow switch be fitted to the return side of the recirculator and wired in series with the torch trigger. This
flow switch will shut down the system and give torch protection should the water flow rate drop below 1.2 Litres per minute. (72 Litres
per hour)
Water-Cooled neck assemblies
Water-Cooled Torch necks are supplied with a location pin. The purpose of this pin is to lock the neck in a positive position. The
location pin registers in one of eight equi-spaced holes drilled in the neck seat.
If a different position is required to one of those eight pre-set positions, the pin can be removed but it must be removed with the Torch
coolant drained from the torch. A gentle pull on the pin will remove it.
