Mild Steel Welding Wire (HTW-58)

HTW-58 except the normal elements of Si, Mn etc, it also contains Ti, which can produce more stable arc, less spatters and fumes
HTW-58 (MAG)

Conform with

GB/T

ER50-G
Description:
HTW-58 except the normal elements of Si ,Mn etc,it also contains Ti, which can produce more stable arc, less spatters and fumes, and also the welded seam has much higher tensile and yield strength.

Application:
It has excellent function when welding under high electricty current, suitabel for welding thicker steel plate, usually used for ship building, bridge, steel structure and engineering mechinery.

Please be noted:
1. Pay attention to the purity of protective gas and suitable proportion of mixed gases.
2. Gas volume is better to controled between 20 -25L /min .
3. Wire protruded from trip within 15 -20mm .
