3.3 Movement and placement
Take care for the welder when moving it, ensure the machine is stood upright and refrain from sloping the machine.
It can also be moved by using the handle on top of the welder. When the machine gets to the destination, it needs to be securely
mounted to avoid sliding.

• The workpiece is connected to the positive electrode of the welding machine, with the welding torch connected to the
negative electrode, called the DC positive connection. Otherwise, it’s called the DC Negative connection. Generally it is usually
operated as a DC positive connection when TIG welding.
• The control cable of the torch switch consists of 2 wires, pedal control of 3 wires and the aero socket has 14 leads.
The MIG160 welding machines’ power supply connects to 220V.
When the power supply voltage is over/under the safe work voltage, the over voltage or under voltage protection inside the
welder will trigger, turning the alarm light on and cutting the current output off.
If the power supply voltage continually goes beyond the safe work voltage range, it will shorten the machines life-span.
The below measures can be used:
•
Change the power supply input net - connect the welder with the stable power supply voltage of the distributor
•
Set the voltage stabilization device in the front of the power cable input
