The MT200-AC/DC is manufactured and compliant with CAN/CSA E60974-1 & ANS/IEC 60974-1,

guaranteeing you electrical safety and performance.

Please view full Warranty terms and conditions

on page 38 of this manual.

s Do not switch the function modes while the machine is welding. Switching of the function

modes during welding can damage the machine. Damage caused in this manner will not be

covered under warranty.

s Disconnect the electrode-holder cable from the machine before switching on the machine,

to avoid arcing should the electrode be in contact with the work piece.

s Operators should be trained and or qualiﬁed.

ELECTRIC SHOCK: It can kill.Touching live electrical parts can cause fatal shocks or severe

burns. The electrode and work circuit is electrically live whenever the output is on. The input

power circuit and internal machine circuits are also live when power is on. Incorrectly installed

or improperly grounded equipment is dangerous.

SAFETY

Welding and cutting equipment can be dangerous to both the operator and people in or near the surrounding working

area, if the equipment is not correctly operated. Equipment must only be used under the strict and comprehensive

observance of all relevant safety regulations. Read and understand this instruction manual carefully before the

installation and operation of this equipment.

www.CKWORLDWIDE.com

FIRE HAZARD: Welding on closed containers, such as tanks, drums, or pipes, can cause them

to explode. Flying sparks from the welding arc, hot work piece, and hot equipment can cause

ﬁres and burns. Accidental contact of electrode to metal objects can cause sparks, explosion,

overheating, or ﬁre. Check and be sure the area is safe before doing any welding.

NOISE CAN DAMAGE HEARING: Noise from some processes or equipment can damage hearing.

Wear approved ear protection if noise level is high.

HOT PARTS: Items being welded generate and hold high heat and can cause severe burns. Do not

touch hot parts with bare hands. Allow a cooling period before working on the welding gun. Use

insulated welding gloves and clothing to handle hot parts and prevent burns.
