Automatic Submerged Arc Welding Machine , Thyristor SAW Welding Machine

MZ-B and ZX- Series Automatic Submerged Arc Welding Machine (Thyristor Type)

Features:

•  As a kind of submerged arc welding machine power source.. It can weld mild steel, low alloy steel ,stainless steel, heat-resistant steel, composite steel etc.

•  The machine adopts three phases rectifying circuit, which has automatic compensation to electric grid fluctuation, to ensure arc stability, good formation of welding seam, output current adjustment is simple, reliable and convenient.

•  Adopts three phases minimum firing angle protection method, to ensure good control of dynamic characteristic.

•  The welding machine has low down feature, it's constant current source and suitable to variable speed wire-feeding submerged arc welding technology.

•  The rated welding current is homologous to rated duty cycle, when duty cycle increased, the welding current will decrease.

•  Automatic spot welding arc-tracing unit driven with light-duty oil cylinder, without compressed air input, output conveyor and inlet pulling rod system are in segments, length and quantity can be chosen according to workpiece length

•  This machine also can be used as the welding source for H beam welding machine and also welding manipulator for tank welding.

Ambient condition:

1. Surrounding environment temperature:

•  During welding: -10℃～+40℃

•  During transportation and storage: -25℃～+55℃

2. Relative humidity:

•  While 40℃, not exceed 50％

•  While 20℃, not exceed 90％

•  The altitude is less than 1000 m

•  For welding machine, the degree of inclination is less than 15°

•  The welding machine can not work in the rail

•  There is no gas, steam,other chemical dust and explosive ,corrosive media which will seriously affect welding machine working.

•  There is no severe vibration and bumps .
