mains voltage
Never take welding machine inside a work piece (eg. container or truck).
Do not place welding machine on a wet surface. Always check cables before
operating the machine. Change defect cables without delay.
Defect cables may cause an injury or set out a fire. Connection cable must not
be compressed, it must not touch sharp edges or hot work pieces.
Welding power circuit
Isolate yourself by using proper protective clothing, do not wear wet
clothing. Never work on a wet surface or use defect cables. Do not put MIG
gun or welding cables on welding machine or on other electric equipment.
Do not press MIG gun switch, if the gun is not directed towards a work piece.
Welding fumes
Take care that there is sufficient ventilation during welding. Take special
safety precautions when welding metals which contain lead, cadmium, zinc,
mercury or beryllium.
2. COnneCting the gun
The gun is equipped with spiral liner for welding normal steel wire.
Before connecting the gun, make sure that its wire liner is according to
recommendations for the welding wire in question.
mtp 350 and 500 with euro adapter:
Set the snap connector carefully at its place so that the control connectors
will not get damaged. Tighten the snap connector carefully in order to avoid
voltage losses. Loose connection will heat the gun and the feeder unit.
Control tightness of connection daily.
mtp 350p and 500p with panasonic adapter:
Push the power connector to its place and tighten the Allen screw carefully.
Set 2-pole control connector and gas connector to their places and tighten
them carefully.
• Before driving the wire into gun check that the wire end is straight at a
length of approx. 200 mm and the tip blunt (file if necessary). A sharp
wire tip may damage wire liner and contact tip of gun.
• Watch out for wire sticking out from welding end of gun. Do not direct
the gun towards people or work piece, instead make sure that the wire
comes freely out in the air.
