1.3 Electrical Shock
• Never touch ‘live’ electrical parts
• Earth clamp all work materials
• Never work in wet or damp environments
Avoid electric shock by:
• Wearing dry, insulated boots
• Using dry, leather gloves
• Never changing electrodes with bare hands or wet gloves
• Never cool electrode holders in water
• Work on a dry, insulated floor where possible
• Never hold the electrode or holder under your arm

2.0 Introduction
The MIG160 adopts the latest pulse width modulation
(PWM) technology and insulated gate bipolar transistor
(IGBT) power module, which allows this machine to be light
weight, small and portable with a low consumption.
The MIG160 also adopts ZVS and PFC full bridge inverter
technology.
In order to improve the efficiency of the power supply
，
this
machine uses ZVS technology and phase-shifting to control
the average current control mode, this results in a more
efficient power factor of the power supply for remarkable
improvement. On top of this, this machine is capable of
performing three types of welding: MMA (Stick), MIG & TIG.
The MIG160 is suitable for all positions welding for various
plates made of stainless steel, carbon steel, alloyed steel,
titanium, magnetsium, cuprum, etc, which is also applicable
to pipe installment, mould mend, petrochemical,
architectural decoration, car and bicycle repairs, handicraft
and common manufacture.
• ZVS soft switch technology reduces IGBT switching loss.
• The efficiency of the machine has a lot of improvement, in
the state of MMA, it can reach nearly 84%.
• The MIG160 uses the average current control mode and
has built in general protection including functions for
limiting pulse width, over-voltage, over-current, over-
heating etc. These functions obviously improve the
stability and security of the machine.
• MCU control system - instant response time to changes.
• Reduced weight of the machine improves portability
